‘Exhilarating’ implant turns thoughts to speech

Scientists have developed a brain implant that can read people’s minds and turn their thoughts to speech.

The team at the University of California, San Francisco says the technology is “exhilarating”.

They add that their findings, published in the journal Nature, could help people when disease robs them of their ability to talk.

Experts said the findings were compelling and offered hope of restoring speech.

How does it work?

The mind-reading technology works in two stages.

First an electrode is implanted in the brain to pick up the electrical signals that manoeuvre the lips, tongue, voice box and jaw.

Then powerful computing is used to simulate how the movements in the mouth and throat would form different sounds.

This results in synthesised speech coming out of a “virtual vocal tract”.
