Researchers have engineered a brain-computer interface (BCI) system that allows users to communicate by decoding neural signals associated with inner speech, rather than attempted speech. Utilizing sensors implanted in the motor cortex, this novel device translates thought into real-time written communication, drawing from a substantial vocabulary of 125,000 words. Tested on individuals with paralysis from ALS and brainstem stroke, this technology greatly enhances communication speed and ease, promising transformative applications for patients with severe speech impairments.
