Neuroscientists are striving to give a voice to people unable to speak in a fast-advancing quest to harness brainwaves to restore or enhance physical abilities.
Researchers at universities across California and companies, such as New York-based Precision Neuroscience, are among those making headway towards generating naturalistic speech through a combination of brain implants and artificial intelligence.
Investment and attention have long been focused on implants that enable severely disabled people to operate computer keyboards, control robotic arms or regain some use of their own paralysed limbs. But some labs are making strides by concentrating on technology that converts thought patterns into speech.
