AI and Brain-Computer Interface Allow Speechless ALS Patient To Work a Full-Time Job

UC Davis researchers say an implanted brain-computer interface has allowed Casey Harrell, an ALS patient who cannot speak, to synthesize sentences from brain activity with 99% accuracy in controlled tests and about 92% accuracy in everyday use. The Register reports that the system has remained usable at home since 2023, helping Harrell communicate naturally, control a computer, and return to full-time work without researchers needing to supervise each session.
