UCSF Researchers Synthesize Speech From Brain Waves

Researchers led by speech neuroscientist Edward Chang at the University of California San Francisco have achieved success at decoding speech attempts in real time by reading the activity in the speech centers of test subjects' brains. Three persons capable of normal speech, who were being treated for epilepsy, participated in the study. They permitted the researchers to make use of tiny recording electrodes that previously were placed on the surface of their brains to map the origins of their seizures in preparation for neurosurgery.
