Neuroscientists decode brain speech signals into written text


Study funded by Facebook aims to improve communication with paralysed patients

The study recording brain signals sent to trigger organ movement is considered a breakthrough.

When Stephen Hawking wanted to speak, he chose letters and words from a synthesiser screen controlled by twitches of a muscle in his cheek.

But the painstaking process the cosmologist used might soon be bound for the dustbin. With a radical new approach, doctors have found a way to extract a person’s speech directly from their brain.

The breakthrough is the first to demonstrate how a person’s intention to say specific words can be gleaned from brain signals and turned into text fast enough to keep pace with natural conversation.
