NASA develops 'thought-reading' software
NASA has developed a computer program that comes close to reading thoughts not yet spoken, by analyzing nerve commands to the throat.
It says the breakthrough holds promise for astronauts and the handicapped.
"A person using the subvocal system thinks of phrases and talks to himself so quietly it cannot be heard, but the tongue and vocal cords do receive speech signals from the brain," said developer Chuck Jorgensen, of NASA's Ames Research Center, Moffett Field, California.
Jorgensen's team found that sensors under the chin and one each
side of the Adam's apple pick up the brain's commands to the speech organs, allowing the subauditory, or "silent speech" to be captured.
The team concluded that the method could be
use
ful on space missions or other difficult working conditions, such as air tra
ffic control towers and even to make current voice-recognition software more active.
"What is analyzed is silent, or subauditory, speech, such as when a person silently reads or talks to himself," Jorgensen said.
