AI can decode speech from brain activity with surprising accuracy
An artificial intelligence can decode words and sentences from brain activity with surprising accuracy.
Using only a few seconds of brain activity data, the AI guesses what a person has heard.
It lists the correct answer in its top 10 possibilities up to 73 percent of the time.
The magnetic or electrical component of brain signals was measured.
Then the team tried to decode what participants had heard using just three seconds of brain activity data.
It then made predictions about what the person might have been hearing during that short time.
Using magnetoencephalography, the correct answer was in the AI’s top 10 guesses up to 73 percent of the time.
