Investigators using satellite imagery to document the war in western Sudan’s Darfur region say 72 villages were burned down in April, the most they have seen since the conflict began. Henry Wilkins talks with the people who do this research about how so-called open-source investigations could be crucial in holding those responsible for the violence to account.

washington — China promotes its help to Southeast Asian countries in modernizing their digital landscapes through investments in infrastructure as part of its “Digital Silk Road.” But rights groups say Beijing is also exporting its model of authoritarian governance of the internet through censorship, surveillance and controls.
China’s state media this week announced Chinese electrical appliance manufacturer Midea Group jointly built its first overseas 5G factory in Thailand with Thai mobile operator AIS, Chinese telecom service provider China Unicom and tech giant Huawei.
The 208,000-square-meter smart factory will have its own 5G network, Xinhua news agency reported.
Earlier this month, Beijing reached an agreement with Cambodia to establish a Digital Law Library of the Association of Southeast Asian Nations (ASEAN) Inter-Parliamentary Assembly. Cambodia’s Khmer Times said the objective is to “expand all-round cooperation in line with the strategic partnership and building a common destiny community.”
But parallel to China’s state media-promoted technology investments, rights groups say Beijing is also helping countries in the region to build what they call “digital authoritarian governance.”
Article 19, an international human rights organization dedicated to promoting freedom of expression globally and named after Article 19 of the Universal Declaration of Human Rights, in an April report said the purpose of the Digital Silk Road is not solely to promote China’s technology industry. The report, China: The rise of digital repression in the Indo-Pacific, says Beijing is also using its technology to reshape the region’s standards of digital freedom and governance to increasingly match its own.
VOA contacted the Chinese Embassy in the U.S. for a response but did not receive one by the time of publication.
Model of digital governance
Looking at case studies of Cambodia, Malaysia, Nepal and Thailand, the Article 19 report says Beijing is spreading China’s model of digital governance along with Chinese technology and investments from companies such as Huawei, ZTE and Alibaba.
Michael Caster, Asia digital program manager with Article 19, told VOA, “China has been successful at providing a needed service, in the delivery of digital development toward greater connectivity, but also in making digital development synonymous with the adoption of PRC [People’s Republic of China]-style digital governance, which is at odds with international human rights and internet freedom principles, by instead promoting notions of total state control through censorship and surveillance, and digital sovereignty away from universal norms.”
The group says in Thailand, home to the world’s largest overseas Chinese community, agreements with China bolstered internet controls imposed after Thailand’s 2014 coup, and it notes that Bangkok has since been considering a China-style Great Firewall, the censorship mechanism Beijing uses to control online content.
In Nepal, the report notes security and intelligence-sharing agreements with China and concerns that Chinese security camera technology is being used to surveil exiled Tibetans, the largest such group outside India.
The group says Malaysia’s approach to information infrastructure appears to increasingly resemble China’s model, citing Kuala Lumpur’s cybersecurity law passed in April and its partnering with Chinese companies whose technology has been used for repressing minorities inside China.
Most significantly, Article 19 says China is involved at “all levels” of Cambodia’s digital ecosystem. Huawei, which is facing increasing bans in Western nations over cybersecurity concerns, has a monopoly on cloud services in Cambodia.
While Chinese companies say they would not hand over private data to Beijing, experts doubt they would have any choice because of national security laws.
Internet gateway
Phnom Penh announced a decree in 2021 to build a National Internet Gateway similar to China’s Great Firewall, restricting the Cambodian people’s access to Western media and social networking sites.
“That we have seen the normalization of a China-style Great Firewall in some of the countries where China’s influence is most pronounced or its digital development support strongest, such as with Cambodia, is no coincidence,” Caster said.
The Cambodian government says the portal will strengthen national security and help combat tax fraud and cybercrime. But the Internet Society, a U.S.- and Switzerland-based nonprofit internet freedom group, says it would allow the government to monitor individual internet use and transactions, and to trace identities and locations.
Kian Vesteinsson, a senior researcher for technology and democracy with rights group Freedom House, told VOA, “The Chinese Communist Party and companies that are aligned with the Chinese state have led a charge internationally to push for internet fragmentation. And when I say internet fragmentation, I mean these efforts to carve out domestic internets that are isolated from global internet traffic.”
Despite Chinese support and investment, Vesteinsson notes that Cambodia has not yet implemented the plan for a government-controlled internet.
“Building the Chinese model of digital authoritarianism into a country’s internet infrastructure is extraordinarily difficult. It’s expensive. It requires technical capacity. It requires state capacity, and all signs point to the Cambodian government struggling on those fronts.”
Vesteinsson says while civil society and foreign political pressure play a role, business concerns are also relevant as requirements to censor online speech or spy on users create costs for the private sector.
“These governments that are trying to cultivate e-commerce should keep in mind that a legal environment that is free from these obligations to do censorship and surveillance will be more appealing to companies that are evaluating whether to start up domestic operations,” he said.
Article 19’s Caster says countries concerned about China’s authoritarian internet model spreading should do more to support connectivity and internet development worldwide.
“This support should be based on human rights law and internet freedom principles,” he said, “to prevent China from exploiting internet development needs to position its services – and often by extension its authoritarian model – as the most accessible option.”
China will hold its annual internet conference in Beijing July 9-11. China’s Xinhua news agency reports this year’s conference will discuss artificial intelligence, digital government, information technology application innovation, data security and international cooperation.

DENVER — The first attempts to regulate artificial intelligence programs that play a hidden role in hiring, housing and medical decisions for millions of Americans are facing pressure from all sides and floundering in statehouses nationwide.
Only one of seven bills aimed at preventing AI’s penchant to discriminate when making consequential decisions — including who gets hired, money for a home or medical care — has passed. Colorado Gov. Jared Polis hesitantly signed the bill on Friday.
Colorado’s bill and those that faltered in Washington, Connecticut and elsewhere faced battles on many fronts, including between civil rights groups and the tech industry, and lawmakers wary of wading into a technology few yet understand and governors worried about being the odd-state-out and spooking AI startups.
Polis signed Colorado’s bill “with reservations,” saying in an statement he was wary of regulations dousing AI innovation. The bill has a two-year runway and can be altered before it becomes law.
“I encourage (lawmakers) to significantly improve on this before it takes effect,” Polis wrote.
Colorado’s proposal, along with six sister bills, are complex, but will broadly require companies to assess the risk of discrimination from their AI and inform customers when AI was used to help make a consequential decision for them.
The bills are separate from more than 400 AI-related bills that have been debated this year. Most are aimed at slices of AI, such as the use of deepfakes in elections or to make pornography.
The seven bills are more ambitious, applying across major industries and targeting discrimination, one of the technology’s most perverse and complex problems.
“We actually have no visibility into the algorithms that are used, whether they work or they don’t, or whether we’re discriminated against,” said Rumman Chowdhury, AI envoy for the U.S. Department of State who previously led Twitter’s AI ethics team.
While anti-discrimination laws are already on the books, those who study AI discrimination say it’s a different beast, which the U.S. is already behind in regulating.
“The computers are making biased decisions at scale,” said Christine Webber, a civil rights attorney who has worked on class action lawsuits over discrimination including against Boeing and Tyson Foods. Now, Webber is nearing final approval on one of the first-in-the-nation settlements in a class action over AI discrimination.
“Not, I should say, that the old systems were perfectly free from bias either,” said Webber. But “any one person could only look at so many resumes in the day. So you could only make so many biased decisions in one day and the computer can do it rapidly across large numbers of people.”
When you apply for a job, an apartment or a home loan, there’s a good chance AI is assessing your application: sending it up the line, assigning it a score or filtering it out. It’s estimated as many as 83% of employers use algorithms to help in hiring, according to the Equal Employment Opportunity Commission.
AI itself doesn’t know what to look for in a job application, so it’s taught based on past resumes. The historical data that is used to train algorithms can smuggle in bias.
Amazon, for example, worked on a hiring algorithm that was trained on old resumes: largely male applicants. When assessing new applicants, it downgraded resumes with the word “women’s” or that listed women’s colleges because they were not represented in the historical data — the resumes — it had learned from. The project was scuttled.
Webber’s class action lawsuit alleges that an AI system that scores rental applications disproportionately assigned lower scores to Black or Hispanic applicants. A study found that an AI system built to assess medical needs passed over Black patients for special care.
Studies and lawsuits have allowed a glimpse under the hood of AI systems, but most algorithms remain veiled. Americans are largely unaware that these tools are being used, polling from Pew Research shows. Companies generally aren’t required to explicitly disclose that an AI was used.
“Just pulling back the curtain so that we can see who’s really doing the assessing and what tool is being used is a huge, huge first step,” said Webber. “The existing laws don’t work if we can’t get at least some basic information.”
That’s what Colorado’s bill, along with another surviving bill in California, are trying to change. The bills, including a flagship proposal in Connecticut that was killed under opposition from the governor, are largely similar.
Colorado’s bill will require companies using AI to help make consequential decisions for Americans to annually assess their AI for potential bias; implement an oversight program within the company; tell the state attorney general if discrimination was found; and inform to customers when an AI was used to help make a decision for them, including an option to appeal.
Labor unions and academics fear that a reliance on companies overseeing themselves means it’ll be hard to proactively address discrimination in an AI system before it’s done damage. Companies are fearful that forced transparency could reveal trade secrets, including in potential litigation, in this hyper-competitive new field.
AI companies also pushed for, and generally received, a provision that only allows the attorney general, not citizens, to file lawsuits under the new law. Enforcement details have been left up to the attorney general.
While larger AI companies have more or less been on board with these proposals, a group of smaller Colorado-based AI companies said the requirements might be manageable by behemoth AI companies, but not by budding startups.
“We are in a brand new era of primordial soup,” said Logan Cerkovnik, founder of Thumper.ai, referring to the field of AI. “Having overly restrictive legislation that forces us into definitions and restricts our use of technology while this is forming is just going to be detrimental to innovation.”
All agreed, along with many AI companies, that what’s formally called “algorithmic discrimination” is critical to tackle. But they said the bill as written falls short of that goal. Instead, they proposed beefing up existing anti-discrimination laws.
Chowdhury worries that lawsuits are too costly and time consuming to be an effective enforcement tool, and laws should instead go beyond what even Colorado is proposing. Instead, Chowdhury and academics have proposed accredited, independent organization that can explicitly test for potential bias in an AI algorithm.
“You can understand and deal with a single person who is discriminatory or biased,” said Chowdhury. “What do we do when it’s embedded into the entire institution?”

Washington — With major military setbacks in recent years, supporters of the Islamic State terror group are increasingly relying on artificial intelligence (AI) to generate online propaganda, experts said.
A new form of propaganda developed by IS supporters is broadcasting news bulletins with AI-generated anchors in multiple languages.
The Islamic State Khorasan (ISKP) group, an IS affiliate active in Afghanistan and Pakistan, produced in a video an AI-generated anchorman to appear reading news following an IS-claimed attack in Bamiyan province in Afghanistan on May 17 that killed four people, including three Spanish tourists.
The digital image posing as an anchor spoke the Pashto language and had features resembling local residents in Bamiyan, according to The Khorasan Diary, a website dedicated to news and analysis on the region.
Another AI-generated propaganda video by Islamic State appeared on Tuesday with a different digital male news anchor announcing IS’s responsibility for a car bombing in Kandahar, Afghanistan.
“These extremists are very effective in spreading deepfake propaganda,” said Roland Abi Najem, a cybersecurity expert based in Kuwait.
He told VOA that a group like IS was already effective in producing videos with Hollywood-level quality, and the use of AI has made such production more accessible for them.
“AI now has easy tools to use to create fake content whether it’s text, photo, audio or video,” Abi Najem said, adding that with AI, “you only need data, algorithms and computing power, so anyone can create AI-generated content from their houses or garages.”
IS formally began using the practice of AI-generated news bulletins four days after an attack at a Moscow music hall on March 22 killed some 145 people. The attack was claimed by IS.
In that video, IS used a “fake” AI-generated news anchor talking about the Moscow attack, experts told The Washington Post last week.
Mona Thakkar, a research fellow at the International Center for the Study of Violent Extremism, said pro-IS supporters have been using character-generation techniques and text-to-speech AI tools to produce translated news bulletins of IS’s Amaq news agency.
“These efforts have garnered positive responses from other users, reflecting that, through future collaborative efforts, many supporters could produce high quality and sophisticated AI-powered propaganda videos for IS of longer durations with better graphics and more innovation techniques,” she told VOA.
Thakkar said she recently came across some pro-IS Arabic-speaking supporters on Telegram who were recommending to other supporters “that beginners use AI image generator bots on Telegram to maintain the high quality of images as the bots are very easy and quick to produce such images.”
AI-generated content for recruitment
While IS’s ability to project power largely decreased due to its territorial defeat in Syria and Iraq, experts say supporters of the terror group believe artificial intelligence offers an alternative to promote their extremist ideology.
“Their content has mainly focused on showing that they’re still powerful,” said Abi Najem. “With AI-generated content now, they can choose certain celebrities that have influence, especially on teenagers, by creating deepfake videos.”
“So first they manipulate these people by creating believable content, then they begin recruiting them,” he said.
In a recent article published on the Global Network on Extremism and Technology, researcher Daniel Siegel said generative AI technology has had a profound impact on how extremist organizations engage in influence operations online, including the use of AI-generated Muslim religious songs, known as nasheeds, for recruitment purposes.
“The strategic deployment of extremist audio deepfake nasheeds, featuring animated characters and internet personalities, marks a sophisticated evolution in the tactics used by extremists to broaden the reach of their content,” he wrote.
Siegel said that other radical groups like al-Qaida and Hamas have also begun using AI to generate content for their supporters.
Cybersecurity expert Abi Najem said he believes the cheap technology will increase the availability of AI-generated content by extremist groups on the internet.
“While currently there are no stringent regulations on the use of AI, it will be very challenging for governments to stop extremist groups from exploiting these platforms for their own gain,” he said.

SYDNEY — A device that absorbs water from air to produce drinkable water was officially launched in Australia Wednesday.
Researchers say the so-called Hydro Harvester, capable of producing up to 1,000 liters of drinkable water a day, could be “lifesaving during drought or emergencies.”
The device absorbs water from the atmosphere. Solar energy or heat that is harnessed from, for example, industrial processes are used to generate hot, humid air. That is then allowed to cool, producing water for drinking or irrigation.
The Australian team said that unlike other commercially available atmospheric water generators, their invention works by heating air instead of cooling it.
Laureate Professor Behdad Moghtaderi, a chemical engineer and director of the University of Newcastle’s Centre for Innovative Energy Technologies, told VOA how the technology operates.
“Hydro Harvester uses an absorbing material to absorb and dissolve moisture from air. So essentially, we use renewable energy, let’s say, for instance, solar energy or waste heat. We basically produce super saturated, hot, humid air out of the system,” Moghtaderi said. “When you condense water contained in that air you would have the drinking water at your disposal.”
The researchers say the device can produce enough drinking water each day to sustain a small rural town of up to 400 people. It could also help farmers keep livestock alive during droughts.
Moghtaderi says the technology could be used in parts of the world where water is scarce.
Researchers were motivated by the fact that Australia is an arid and dry country.
“More than 2 billion people around the world, they are in a similar situation where they do not have access to, sort of, high-quality water and they deal with water scarcity,” Moghtaderi said
Trials of the technology will be conducted in several remote Australian communities this year.
The World Economic Forum, an international research organization, says “water scarcity continues to be a pervasive global challenge.”
It believes that atmospheric water generation technology is a “promising emergency solution that can immediately generate drinkable water using moisture in the air.”
However, it cautions that generally the technology is not cheap, and estimates that one mid-sized commercial unit can cost between $30,000 and $50,000.

SYDNEY — Researchers in Australia and the United States say that a new artificial intelligence tool has allowed them to classify brain tumors more quickly and accurately.
The current method for identifying different kinds of brain tumors, while accurate, can take several weeks to produce results. The method, called DNA methylation-based profiling, is not available at many hospitals around the world.
To address these challenges, a research team from the Australian National University, in collaboration with the National Cancer Institute in the United States, has developed a way to predict DNA methylation, which acts like a switch to control gene activity.
This allows them to classify brain tumors into 10 major categories using a deep learning model.
This is a branch of artificial intelligence that teaches computers to process data in a way that is inspired by a human brain.
The joint U.S.-Australian system is called DEPLOY and uses microscopic pictures of a patient’s tissue called histopathology images.
The researchers see the DEPLOY technology as complementary to an initial diagnosis by a pathologist or physician.
Danh-Tai Hoang, a research fellow at the Australian National University, told VOA that AI will enhance current diagnostic methods that can often be slow.
“The technique is very time consuming,” Hoang said. “It is often around two to three weeks to obtain a result from the test, whereas patients with high-grade brain tumors often require treatment as soon as possible because time is the goal for brain tumor(s), so they need to get treatment as soon as possible.”
The research team said its AI model was validated on large datasets of approximately 4,000 patients from across the United States and Europe and an accuracy rate of 95 percent.
Their study has been published in the journal Nature Medicine.

Accra, Ghana — Anita Akpeere prepared fried rice in her kitchen in Ghana’s capital as a flurry of notifications for restaurant orders lit up apps on her phone. “I don’t think I could work without a phone in my line of business,” she said, as requests came in for her signature dish, a traditional fermented dumpling.
Internet-enabled phones have transformed many lives, but they can play a unique role in sub-Saharan Africa, where infrastructure and public services are among the world’s least developed, said Jenny Aker, a professor who studies the issue at Tufts University. At times, technology in Africa has leapfrogged gaps, including providing access to mobile money for people without bank accounts.
Despite growing mobile internet coverage on the continent of 1.3 billion people, just 25% of adults in sub-Saharan Africa have access to it, according to Claire Sibthorpe, head of digital inclusion at the U.K.-based mobile phone lobbying group GSMA. Expense is the main barrier. The cheapest smartphone costs up to 95% of the monthly salary for the poorest 20% of the region’s population, Sibthorpe said.
Literacy rates that are below the global average, and lack of services in many African languages — some 2,000 are spoken across the continent, according to The African Language Program at Harvard University — are other reasons why a smartphone isn’t a compelling investment for some.
“If you buy a car, it’s because you can drive it,” said Alain Capo-Chichi, chief executive of CERCO Group, a company that has developed a smartphone that functions through voice command and is available in 50 African languages such as Yoruba, Swahili and Wolof.
Even in Ghana, where the lingua franca is English, knowing how to use smartphones and apps can be a challenge for newcomers.
One new company in Ghana is trying to close the digital gap. Uniti Networks offers financing to help make smartphones more affordable and coaches users to navigate its platform of apps.
For Cyril Fianyo, a 64-year-old farmer in Ghana’s eastern Volta region, the phone has expanded his activities beyond calls and texts. Using his identity card, he registered with Uniti, putting down a deposit worth 340 Ghanaian Cedis ($25) for a smartphone and will pay the remaining 910 Cedis ($66) in installments.
He was shown how to navigate apps that interested him, including a third-party farming app called Cocoa Link that offers videos of planting techniques, weather information and details about the challenges of climate change that have affected cocoa and other crops.
Fianyo, who previously planted according to his intuition and rarely interacts with farming advisors, was optimistic that the technology would increase his yields.
“I will know the exact time to plant because of the weather forecast,” he said.
Kami Dar, chief executive of Uniti Networks, said the mobile internet could help address other challenges including accessing health care. The company has launched in five communities across Ghana with 650 participants and wants to reach 100,000 users within five years.
Aker, the scholar, noted that the potential impact of mobile phones across Africa is immense but said there is limited evidence that paid health or agriculture apps are benefiting people there. She asserted that the only beneficial impacts are reminders to take medicine or get vaccinated.
Having studied agricultural apps and their impact, she said it doesn’t seem that farmers are getting better prices or improving their income.
Capo-Chichi from CERCO Group said a dearth of useful apps and content is another reason that more people in Africa aren’t buying smartphones.
Dar said Uniti Networks learns from mistakes. In a pilot in northern Ghana designed to help cocoa farmers contribute to their pensions, there was high engagement, but farmers didn’t find the app user-friendly and needed extra coaching. After the feedback, the pension provider changed the interface to improve navigation.
Others are finding benefit with Uniti’s platform. Mawufemor Vitor, a church secretary in Hohoe, said one health app has assisted her to track her menstruation to help prevent pregnancy. And Fianyo, the farmer, has used the platform to find information on herbal medicine.
But mobile phones are no substitute for investment in public services and infrastructure, Aker said.
She also expressed concerns about the privacy of data in the hands of private technology providers and governments. With digital IDs in development in African nations such as Kenya and South Africa, this could pave the way for further abuses, Aker said.
Uniti Networks is a for-profit business, paid for each customer that signs up for paying apps. Dar asserted that he was not targeting vulnerable populations to sell them unnecessary services and said Uniti only features apps that align with its idea of impact, with a focus on health, education, finance and agriculture.
Dar said Uniti has rejected lucrative approaches from many companies including gambling firms. “Tech can be used for awful things,” he said.
He acknowledged that Uniti tracks users on the platform to provide incentives, in the form of free data, and to provide feedback to app developers. He acknowledged that users’ health and financial data could be at threat from outside attack but said Uniti has decentralized data storage in an attempt to lessen the risk.
Still, the potential to provide solutions can outweigh the risks, Aker said, noting two areas where the technology could be transformative: education and insurance.
She said mobile phones could help overcome the illiteracy that still affects 773 million people worldwide according to UNESCO. Increased access to insurance, still not widely used in parts of Africa, could provide protection to millions who face shocks on the front lines of climate change and conflict.
Back in Fianyo’s fields, his new smartphone has attracted curiosity. “This is something I would like to be part of,” said neighboring farmer Godsway Kwamigah.

PROVIDENCE, RHODE ISLAND — The voice Alexis “Lexi” Bogan had before last summer was exuberant.
She loved to belt out Taylor Swift and Zach Bryan ballads in the car. She laughed all the time — even while corralling misbehaving preschoolers or debating politics with friends over a backyard fire pit. In high school, she was a soprano in the chorus.
Then that voice was gone.
Doctors in August removed a life-threatening tumor lodged near the back of her brain. When the breathing tube came out a month later, Bogan had trouble swallowing and strained to say “Hi” to her parents. Months of rehabilitation aided her recovery, but her speech is still impaired. Friends, strangers and her own family members struggle to understand what she is trying to tell them.
In April, the 21-year-old got her old voice back. Not the real one, but a voice clone generated by artificial intelligence that she can summon from a phone app. Trained on a 15-second time capsule of her teenage voice — sourced from a cooking demonstration video she recorded for a high school project — her synthetic but remarkably real-sounding AI voice can now say almost anything she wants.
She types a few words or sentences into her phone and the app instantly reads it aloud.
“Hi, can I please get a grande iced brown sugar oat milk shaken espresso,” said Bogan’s AI voice as she held the phone out her car’s window at a Starbucks drive-thru.
Experts have warned that rapidly improving AI voice-cloning technology can amplify phone scams, disrupt democratic elections and violate the dignity of people — living or dead — who never consented to having their voice recreated to say things they never spoke.
It’s been used to produce deepfake robocalls to New Hampshire voters mimicking President Joe Biden. In Maryland, authorities recently charged a high school athletic director with using AI to generate a fake audio clip of the school’s principal making racist remarks.
But Bogan and a team of doctors at Rhode Island’s Lifespan hospital group believe they’ve found a use that justifies the risks. Bogan is one of the first people — the only one with her condition — who have been able to recreate a lost voice with OpenAI’s new Voice Engine. Some other AI providers, such as the startup ElevenLabs, have tested similar technology for people with speech impediments and loss — including a lawyer who now uses her voice clone in the courtroom.
“We’re hoping Lexi’s a trailblazer as the technology develops,” said Dr. Rohaid Ali, a neurosurgery resident at Brown University’s medical school and Rhode Island Hospital. Millions of people with debilitating strokes, throat cancer or neurogenerative diseases could benefit, he said.
“We should be conscious of the risks, but we can’t forget about the patient and the social good,” said Dr. Fatima Mirza, another resident working on the pilot. “We’re able to help give Lexi back her true voice and she’s able to speak in terms that are the most true to herself.”
Mirza and Ali, who are married, caught the attention of ChatGPT-maker OpenAI because of their previous research project at Lifespan using the AI chatbot to simplify medical consent forms for patients. The San Francisco company reached out while on the hunt earlier this year for promising medical applications for its new AI voice generator.
Bogan was still slowly recovering from surgery. The illness started last summer with headaches, blurry vision and a droopy face, alarming doctors at Hasbro Children’s Hospital in Providence. They discovered a vascular tumor the size of a golf ball pressing on her brain stem and entangled in blood vessels and cranial nerves.
“It was a battle to get control of the bleeding and get the tumor out,” said pediatric neurosurgeon Dr. Konstantina Svokos.
The tumor’s location and severity coupled with the complexity of the 10-hour surgery damaged Bogan’s control of her tongue muscles and vocal cords, impeding her ability to eat and talk, Svokos said.
“It’s almost like a part of my identity was taken when I lost my voice,” Bogan said.
The feeding tube came out this year. Speech therapy continues, enabling her to speak intelligibly in a quiet room but with no sign she will recover the full lucidity of her natural voice.
“At some point, I was starting to forget what I sounded like,” Bogan said. “I’ve been getting so used to how I sound now.”
Whenever the phone rang at the family’s home in the Providence suburb of North Smithfield, she would push it over to her mother to take her calls. She felt she was burdening her friends whenever they went to a noisy restaurant. Her dad, who has hearing loss, struggled to understand her.
Back at the hospital, doctors were looking for a pilot patient to experiment with OpenAI’s technology.
“The first person that came to Dr. Svokos’ mind was Lexi,” Ali said. “We reached out to Lexi to see if she would be interested, not knowing what her response would be. She was game to try it out and see how it would work.”
Bogan had to go back a few years to find a suitable recording of her voice to “train” the AI system on how she spoke. It was a video in which she explained how to make a pasta salad.
Her doctors intentionally fed the AI system just a 15-second clip. Cooking sounds make other parts of the video imperfect. It was also all that OpenAI needed — an improvement over previous technology requiring much lengthier samples.
They also knew that getting something useful out of 15 seconds could be vital for any future patients who have no trace of their voice on the internet. A brief voicemail left for a relative might have to suffice.
When they tested it for the first time, everyone was stunned by the quality of the voice clone. Occasional glitches — a mispronounced word, a missing intonation — were mostly imperceptible. In April, doctors equipped Bogan with a custom-built phone app that only she can use.
“I get so emotional every time I hear her voice,” said her mother, Pamela Bogan, tears in her eyes.
“I think it’s awesome that I can have that sound again,” added Lexi Bogan, saying it helped “boost my confidence to somewhat where it was before all this happened.”
She now uses the app about 40 times a day and sends feedback she hopes will help future patients. One of her first experiments was to speak to the kids at the preschool where she works as a teaching assistant. She typed in “ha ha ha ha” expecting a robotic response. To her surprise, it sounded like her old laugh.
She’s used it at Target and Marshall’s to ask where to find items. It’s helped her reconnect with her dad. And it’s made it easier for her to order fast food.
Bogan’s doctors have started cloning the voices of other willing Rhode Island patients and hope to bring the technology to hospitals around the world. OpenAI said it is treading cautiously in expanding the use of Voice Engine, which is not yet publicly available.
A number of smaller AI startups already sell voice-cloning services to entertainment studios or make them more widely available. Most voice-generation vendors say they prohibit impersonation or abuse, but they vary in how they enforce their terms of use.
“We want to make sure that everyone whose voice is used in the service is consenting on an ongoing basis,” said Jeff Harris, OpenAI’s lead on the product. “We want to make sure that it’s not used in political contexts. So we’ve taken an approach of being very limited in who we’re giving the technology to.”
Harris said OpenAI’s next step involves developing a secure “voice authentication” tool so that users can replicate only their own voice. That might be “limiting for a patient like Lexi, who had sudden loss of her speech capabilities,” he said. “So we do think that we’ll need to have high-trust relationships, especially with medical providers, to give a little bit more unfettered access to the technology.”
Bogan has impressed her doctors with her focus on thinking about how the technology could help others with similar or more severe speech impediments.
“Part of what she has done throughout this entire process is think about ways to tweak and change this,” Mirza said. “She’s been a great inspiration for us.”
While for now she must fiddle with her phone to get the voice engine to talk, Bogan imagines an AI voice engine that improves upon older remedies for speech recovery — such as the robotic-sounding electrolarynx or a voice prosthesis — in melding with the human body or translating words in real time.
She’s less sure about what will happen as she grows older and her AI voice continues to sound like she did as a teenager. Maybe the technology could “age” her AI voice, she said.
For now, “even though I don’t have my voice fully back, I have something that helps me find my voice again,” she said.

new york — Your wallet may soon be getting thinner.
Visa on Wednesday announced major changes to how credit and debit cards will operate in the U.S. in the coming months and years.
The new features could mean Americans will be carrying fewer physical cards in their wallets, and will make the 16-digit credit or debit card number printed on every card increasingly irrelevant.
They will be some of the biggest changes to how payments operate in the U.S. since the U.S. rolled out chip-embedded cards several years ago. They also come as Americans have many more options to pay for purchases beyond “credit or debit,” including buy now, pay later companies, peer-to-peer payment options, paying directly with a bank, or digital payment systems such as Apple Pay.
“I think (with these features) we’re getting past the point where consumers may never need to manually enter an account number ever again,” said Mark Nelsen, Visa’s global head of consumer payments.
The biggest change coming for Americans will be the ability for banks to issue one physical payment card that will be connected to multiple bank accounts. That means no more carrying, for example, a Bank of America or Chase debit card as well as their respective credit cards in a physical wallet. Americans will be able to set criteria with their bank — such as having all purchases below $100 or with a certain merchant applied to the debit card, while other purchases go on the credit card.
The feature, already being used in Asia, will be available this summer. Buy now, pay later company Affirm is the first of Visa’s customers to roll out the feature in the U.S.

Some of Visa’s new features are in response to online-payments fraud, which continues to increase as more countries adopt digital payments. The company based in San Francisco, California, estimates that payment fraud happens roughly seven times more often online than it does in person, and there are now billions of stolen credit and debit card numbers available to criminals.
Other new elements are also in response to features that non-payments companies have rolled out in recent years. The Apple Card, which uses Mastercard as its payment network, does not come with a printed 16-digit account number and Apple Card users can request a fresh credit card number at any time without having to dispose of the physical card.
Visa executives see a future where banks will issue cards where the 16-digit account number, if the new cards come with them, is largely symbolic.
Soon, fingerprints can approve transactions
Among the other updates unveiled by Visa are changes to tap-to-pay features. Americans will be able to tap their credit or debit cards to their smartphones to add the card to mobile wallets, instead of using a smartphone’s camera to scan in a card’s information, or tap the card to their smartphones to approve a transaction online. Visa will also start implementing biometrics to approve transactions, similar to how Apple devices use a fingerprint or face scan to approve transactions.
The features will take time to filter down to the banks, which will decide when or what to implement for their customers. But because the banks and credit card companies are Visa’s customers, and issue cards with the Visa label, these are features that the financial institutions have been asking for.

Washington — Aleksander Dugin, a Russian nationalist ideologue and strong supporter of President Vladimir Putin, has been bombarded with attacks on Chinese social media, where netizens criticized and mocked his Russian expansionist views that had once included the dismembering of China.
Two years after Putin launched an invasion of Ukraine, pro-Russia sentiment has been prevalent on Chinese internet.
But the backlash against Dugin has revealed a less mentioned side of what has so far appeared to be a cozy alliance between Beijing and Moscow — hostility between Chinese nationalists and their Russian counterparts, the result of centuries of territorial disputes and political confrontations that Beijing has been reticent about displaying publicly in recent decades.
On May 6, Dugin opened an account on two of the most popular Chinese social media apps Weibo, China’s X, formerly known as Twitter, and Bilibili, a YouTube-like video site.
In the first video posted on both Weibo and Bilibili, Dugin greeted the Chinese audience and praised Beijing’s economic and political achievements in recent decades.
In the same video, he also criticized an article published in April in The Economist by Feng Yujun, director of Russian and Central Asian studies at Fudan University in Shanghai. Feng said in the article that Russia will inevitably lose the Ukraine war.
Dugin countered that Feng and some Chinese people underestimated Russia’s “tenacity and perseverance.”
The video was quickly condemned by Chinese citizens, who posted comments such as “Russia must lose,” which received thousands of likes.
“This is an extremist who is extremely unfriendly to China and has made plans to dismember China,” another message posted by a Weibo user named “Zhixingbenyiti” said.
Dugin, 62, was born in Moscow. In the 1980s, he became an anti-communist dissident.
After the collapse of the Soviet Union, he began to promote Russian expansionism. He believes that Moscow’s territorial expansion in Eurasia will allow it to counter Western forces led by the United States.
In his 1997 book, Foundations of Geopolitics, Dugin wrote that dismembering China was a necessary step for Russia to become strong. People within Putin’s inner circle have reportedly shown interest in Dugin’s writing, which gave rise to his nickname “Putin’s brain.”
However, Dugin’s attitude toward China has changed significantly in recent years. In 2018, he visited China for the first time. In a speech at Fudan University, he praised China’s economy, culture and leadership in the fight against colonialism.
He also changed his previous support for containing China and said in a speech that China and Russia could work together to “form a very important and non-negligible containment/pull effect” on Western powers.
Dugin is now a senior fellow at Fudan University’s China Institute and one of the columnists for China’s nationalist news organization, Guancha.
Before Russia invaded Ukraine in February 2022, Dugin said in a column that the alliance between China and Russia would “mean the irreversible end of Western hegemony.”
Philipp Ivanov, a senior fellow at the Asia Society Policy Institute, told VOA that “Dugin is an opportunist. As the Ukraine war dramatically accelerated the alignment between China and Russia, his position started to change, resulting in his current attempt to engage with China’s intellectual and broader community.”
Ivanov also thinks Dugin’s influence on the Kremlin has been exaggerated.
Since joining Chinese social media, Dugin has gained more than 100,000 followers on Weibo and 25,000 followers on BiliBili. He has published fewer than five posts on Weibo, but nearly every one of them has more than 1,000 comments, most of which criticized him.
Under a post in which Dugin supported Putin on his fifth presidential term, people responded with comments such as “Russia is about to lose the war” and “The gates of hell are waiting for you.”
Wang Xiaodong, China’s most influential nationalist scholar, shared a Weibo post he made two years ago criticizing Dugin and Chinese pro-Russian groups.
“Introducing Dugin’s ideas is not because I worry that the Kremlin will implement his ideas; He has the intention but not the strength! I just want to tell the Chinese people how some Russians, including elites in the powerful departments, view China. Do we Chinese need to risk our lives for them?” the post read.
Ivanov was not surprised by the attacks on Dugin on the Chinese internet.
“While Chinese netizens may support Putin’s anti-Western/anti-US agenda, they are skeptical or outright negative about Russia’s assault on an independent country’s sovereignty and Russian expansionism, nationalism and chauvinism (which Dugin represents),” he told VOA in an email.
He said the history of China-Russia relations is predominantly about confrontation, competition and mistrust.
Among the attacks on Dugin, many netizens also brought up former Chinese territories that Russia occupied in the past 200 years.
“For the sake of ever-lasting friendship between China and Russia, please return Sakhalin and Vladivostok,” one Weibo comment posted by “lovejxcecil” read.
Although China has not been involved in the war, the Russia-Ukraine war has been a hot topic on the Chinese internet.
According to Eric Liu, a former Weibo censor, Dugin’s joining the platform undoubtedly brought more traffic to Weibo. However, it also means that Weibo needs to invest more resources in censorship to prevent him from making remarks that Beijing considers sensitive.
“He is a foreigner. He has no idea about China’s ‘political correctness’ or where the boundaries are,” Liu said. “This risk will have to be taken care of by Weibo, which brought him in.”
On Thursday, Dugin posted on Weibo that China and Russia could achieve “anything” together. His comment section has been turned off.

WASHINGTON — U.S. prosecutors on Thursday announced the arrests of an American woman and a Ukrainian man they say helped North Korea-linked IT workers posing as Americans to obtain remote-work jobs at hundreds of U.S. companies.
The U.S. Department of Justice (DoJ) said the elaborate scheme, aimed at generating revenue for North Korea in contravention of international sanctions, involved the infiltration of more than 300 U.S. firms, including Fortune 500 companies and banks, and the theft of the identities of more than 60 Americans.
A DoJ statement said the overseas IT workers also attempted to gain employment and access to information at two U.S. government agencies, although these efforts were “generally unsuccessful.”
An earlier State Department statement said the scheme had generated at least $6.8 million for North Korea. It said the North Koreans involved were linked to North Korea’s Munitions Industry Department, which oversees development of the country’s ballistic missiles, weapons production, and research and development programs.
An indictment filed in federal court in Washington last week and unsealed on Thursday said charges had been filed against Christina Marie Chapman, 49, of Litchfield Park, Arizona; Ukrainian Oleksandr Didenko, 27, of Kyiv; and three other foreign nationals.
A Justice Department statement said Chapman was arrested on Wednesday, while Didenko was arrested on May 7 by Polish authorities at the request of the United States, which is seeking his extradition.
The State Department announced a reward of up to $5 million for information related to Chapman’s alleged co-conspirators, who used the aliases Jiho Han, Haoran Xu and Chunji Jin, and another unindicted individual using the aliases Zhonghua and Venechor S.
Court records did not list lawyers for those arrested and it was not immediately clear whether they had legal representation.
The head of the Justice Department’s Criminal Division, Nicole Argentieri, said the alleged crimes “benefited the North Korean government, giving it a revenue stream and, in some instances, proprietary information stolen by the co-conspirators.”
The charges “should be a wakeup call for American companies and government agencies that employ remote IT workers,” she said in the statement.
It said the scheme “defrauded U.S. companies across myriad industries, including multiple well-known Fortune 500 companies, U.S. banks, and other financial service providers.”
The DoJ said Didenko was accused of creating fake accounts at U.S. IT job search platforms, selling them to overseas IT workers, some of whom he believed were North Korean. It said overseas IT workers using Didenko’s services were also working with Chapman.
Didenko’s online domain, upworksell.com, was seized Thursday by the Justice Department, the statement said.
The DOJ statement said the FBI executed search warrants for U.S.-based “laptop farms” – residences that hosted multiple laptops for overseas IT workers.
It said that through these farms, including one Chapman hosted from her home, U.S.-based facilitators logged onto U.S. company computer networks and allowed the overseas IT workers to remotely access the laptops, using U.S. IP addresses to make it appear they were in the United States.
The statement said search warrants for four U.S. residences associated with laptop farms controlled by Didenko were issued in the Southern District of California, the Eastern District of Tennessee, and Eastern District of Virginia, and executed between May 8 and May 10.
North Korea is under U.N. sanctions aimed at cutting funding for its missile and nuclear weapons programs and experts say it has sought to generate income illicitly, including through IT workers.
Confidential research by a now-disbanded U.N. sanctions monitoring panel seen by Reuters on Tuesday showed they had been investigating 97 suspected North Korean cyberattacks on cryptocurrency companies between 2017 and 2024, valued at some $3.6 billion.
The U.N. sanctions monitors were disbanded at the end of April after Russia vetoed renewal of their mandate.
A research report from a Washington think tank in April said North Korean animators may have helped create popular television cartoons for big Western firms despite international sanctions.

TAIPAI, TAIWAN — Taiwanese chipmaker TSMC said Thursday there was no damage to its facilities after an incident at its Arizona factory construction site where
a waste disposal truck driver was transported to a hospital.
Firefighters responded to a reported explosion Wednesday afternoon at the Taiwan Semiconductor Manufacturing Company plant in Phoenix, the Arizona Republic reported, citing the local fire department.
TSMC, the world’s largest contract chipmaker whose clients include Apple and Nvidia, said in a statement none of its employees or onsite construction workers had reported any related injuries.
“This is an active investigation with no additional details that can be shared at this time,” it added.
TSMC’s Taipei-listed shares pared earlier gains after the news and were last up around 0.8% on Thursday morning. TSMC last month agreed to expand its planned investment by $25 billion to $65 billion and to add a third Arizona plant by 2030.
The company will produce the world’s most advanced 2 nanometer technology at its second Arizona facility expected to begin production in 2028.
