Lots of people are concerned about the ability that artificial intelligence (AI) has to copy their voices. When AI is used to make false recordings2 of things that a person never said, it is called a "deepfake."
However, more and more stories are coming out about how AI is helping3 people who can no longer speak, regain4 a version of their voice.
For example, country music singer Randy Travis recently released his first new song in over 10 years with the help of AI technology. Travis suffered a stroke and can no longer sing.
The technology is also able to help people like 21-year-old Alexis "Lexi" Bogan from the eastern state of Rhode Island.
Bogan used to love singing along with songs by her favorite musicians like Taylor Swift and Zach Bryan. She was a singer in her school music group as a teenager. If she was spending time with friends, she would be the loudest during a discussion about politics over a large fire in the back yard.
But a surprise diagnosis5 changed all that. Last August, doctors removed a tumor6 from the back of her brain. The surgery was a success. But after doctors removed a tube used to help her breathe during the operation, Bogan had trouble speaking.
Bogan is working with therapists and has regained7 some ability to speak, but there is no sign that she will ever be able to speak like she used to.
Last month, Bogan got her voice back in a way. Experts created a tool for her using AI. She uses a text-to-voice app on her phone so she can now do things like order her favorite coffee at Starbucks. She uses it by writing words in her phone and holding it up at the coffee shop so servers can hear her.
The app uses OpenAI's voice tool. Programmers trained the app using a 15-second sound recording1 from a cooking video Bogan made as a teenager. Most of the video had cooking sounds, so that is all they could use. But it was enough.
Bogan's doctors say Lexi's case shows why AI can be helpful.
Dr. Rohaid Ali is training in neuroscience at Brown University's medical school. He called Bogan "a trailblazer." He said the technology can help millions of people with brain injuries, throat cancer or other diseases that prevent a person from speaking.
Fatima Mirza is another doctor working on the project. She said there is a risk that AI technology can be used by bad people, "but we can't forget about the patient and the social good." She said the technology permits Bogan to have something close to her true voice.
The doctors had already worked with OpenAI on an earlier project. When they found out the company wanted to test their voice generator8 to help patients, they thought of Bogan.
Bogan said "it's almost like a part of my identity was taken when I lost my voice."
She said she was starting to forget what her real voice sounded like before she started using the app.
The app makes mistakes, but people who know Bogan do not seem worried. They are just happy to hear Lexi's voice.
"I get so emotional every time I hear her voice," said her mother, Pamela, with tears in her eyes.
Bogan said it helped "boost my confidence to somewhat where it was before all this happened." She said she uses the app about 40 times per day.
The doctors are working with other patients to gather voice samples and they hope to bring the app to other hospitals around the world. But right now, the app, called Voice Engine, is not publicly available. Other AI companies, however, are making their voice-cloning services available to entertainment companies or other organizations.
Jeff Harris is OpenAI's project leader for Voice Engine. He said the company is "very limited in who we're giving the technology to" because they want to be sure everyone whose voice is being used has given permission.
Bogan believes the technology will progress over time so that when she is older, she does not have to depend on the voice she had as a teenager. She is excited that she is contributing to a change that will help people who are currently using robotic-sounding voices.
For now, "even though I don't have my voice fully9 back, I have something that helps me find my voice again," she said.
