A man who lost his voice to ALS is back at a full-time job, speaking through a brain implant
UC Davis researchers fitted a man with ALS with a brain implant whose AI turns his attempted speech into words with about 99% accuracy. He has used it for more than 3,800 hours since 2023 and now works full time as an environmental advocate.
Why it matters
Losing the ability to speak is one of the cruelest parts of ALS. This system runs at home, about five hours a day, with no researcher in the room. That's the difference between a lab demo and a life.
Back to work, in his own words.
