Breakthrough implant reads your thoughts and converts them to speech

A new thought-reading brain implant is giving people who can’t speak a chance to communicate again. Developed by researchers at UC Berkeley, this experimental technology can convert neural activity into spoken words with a delay of just a few seconds. It’s one of the closest breakthroughs yet toward real-time thought-to-voice communication.

The system works by placing 253 electrodes on the surface of the brain, specifically targeting the motor cortex. This is the region of the brain responsible for coordinating speech.
