A brain implant that uses artificial intelligence (AI) can almost instantaneously decode a person’s thoughts and stream them through a speaker, new research shows. This is the first time researchers have achieved near-synchronous brain-to-voice streaming.
The experimental mind-reading technology is designed to give a synthetic voice to people with severe paralysis who cannot speak. It works by putting electrodes onto the brain’s surface as part of an implant called a neuroprosthesis, which allows scientists to identify and interpret speech signals.
The brain-computer interface (BCI) uses AI to decode neural signals and can stream intended speech from the brain in close to real time, according to a statement released by the University of California (UC), Berkeley. The team previously unveiled an earlier version of the technology in 2023, but the new version is quicker and less robotic.
