ALS Patient Casey Harrell Speaks Again with 97% Accurate Brain-Computer Interface

Aug 15, 2024, 02:19 PM

A groundbreaking brain-computer interface has enabled an ALS patient, Casey Harrell, to speak clearly again. The system, which involves 256 electrodes implanted in the brain, works by decoding the patient’s intended speech with over 97% accuracy and reproducing it in his natural voice. This technology was developed by researchers at the University of California and documented in the New England Journal of Medicine. It utilizes a combination of brain implants and artificial intelligence to recognize words the patient attempts to speak, allowing him to communicate with family and friends. The successful implementation of this speech neuroprosthesis marks a significant advancement in assistive technology for individuals with neurological conditions. The patient, a 45 year-old, had lost his ability to speak due to ALS.
