Cutting-edge neural prosthetics have advanced to decode inner speech, enabling individuals with severe speech impairments to communicate by thinking their intended sentences. This system builds upon technology that interprets motor cortex activity linked to vocal tract movements but uniquely captures imagined speech. Demonstrated on patients with ALS and brainstem stroke, the device translates neural signals into real-time text with a vocabulary exceeding 125,000 words. Published in Cell, this breakthrough may transform communication options for paralyzed patients beyond existing methods reliant on physical attempts to speak.
