A novel brain-computer interface developed by neuroscientists allows individuals with severe speech impairments to communicate by decoding inner speech directly from motor cortex neural signals. Unlike prior systems requiring attempted speech, this technology interprets imagined sentences in near real-time, encompassing a vocabulary of 125,000 words. Trials with patients suffering from ALS and brain stem strokes demonstrate its promise for restoring fluid communication in locked-in individuals, marking a significant leap for neural prosthetics and assistive devices.
