Casey Harrell, a man with ALS, has become the first "power user" of a brain-computer interface (BCI) designed to restore speech. After nearly three years and thousands of hours of use, Harrell can now communicate independently, surf the web, and even perform his job using the implanted electrodes. The system decodes neural activity from the speech motor cortex to generate phonemes, which are then converted into words with high accuracy, enabling him to speak sentences and expand his vocabulary significantly.
