Researchers have been able to translate brain signals into speech using sensors attached to the surface of the brain for the first time.

The breakthrough, which is up to 90 per cent accurate, offers a way to communicate for paralysed patients who cannot speak and could eventually lead to being able to read anyone thoughts.

"We were beside ourselves with excitement when it started working," said Professor Bradley Greger, a bioengineer at Utah University who led the team of researchers.

"It was just one of the moments when everything came together.

"We have been able to decode spoken words using only signals from the brain with a device that has promise for long-term use in paralysed patients who cannot now speak.

"I would call it brain reading and we hope that in two or three years it will be available for use for paralysed patients."
