Speak Soundlessly To Your Computer


Researchers at the MIT Media Lab developed a device named AlterEgo that attaches round the lips and enables users to communicate with computers with no audible voice or discernible movements.

The gadget works on the principle that a person’s inaudible internal speech is echoed by neuromuscular signals. AlterEgo system captures the signals to reconstruct one’s words.

Studies demonstrate 92% word accuracy levels but the device is not yet ready for mass production.

Earlier speechless devices rely on brain-signal-detecting devices implanted in the head.
