How a Brain Implant and AI Gave a Woman with Paralysis Her Voice Back
Meet Ann, a stroke survivor paralyzed since 2005, who has found a voice again.
Through an AI brain implant developed by @ucsfneurosurgery and Chang Lab, she can express some words and sentences using synthesized speech and a digital avatar.
Tiny electrodes implanted on the brain's surface decode signals linked to Ann's speech attempts. Using custom-built algorithms, the system recognizes phonemes, the building blocks of speech, enabling Ann to form words and sentences.
Ann hopes that the system will one day help paralyzed people work again. "They'll be able to rejoin the world and make their own contributions to society," says Ann.
