Mind-reading technology uses AI to give voice to people unable to speak

New technology that can read minds and turn thoughts into complete sentences with the help of AI is giving hope to people who can't speak. Researchers from the University of California say their technology is able to translate brain activity into English word by word with the help of machine learning. The technology could revolutionise the way people who can't speak or move are able to communicate, as it is more natural than existing tools, the team say. It has an accuracy rate of 97 per cent - more than twice as high as other brain-signal decoding devices and works by mapping activity of neurons to words. Translating neurons to words enables it to type word sequences on a computer interface in real time - which can then be read out by a synthetic voice.
