Brain-Computer Interface and AI Let Speechless ALS Patient Speak and Work Full-Time
A UC Davis brain-computer interface has enabled Casey Harrell, a paralyzed ALS patient, to communicate independently for over 3,800 hours across two years with 99% accuracy in controlled tests. Using AI-driven speech synthesis, the BCI implant translates neural activity into speech, allowing him to work full-time as an environmental advocate and have conversations with his daughter who's never heard his voice.
