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.

Fraud prompts changes

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.
