New Sensors Detect Speech Without Sound

Tech May Yield Clearer Cell Calls in Noisy Places phone

Cell phone fanatics take note: New, non-acoustic sensor technology means that one day, you won't have to shout into your phone to be heard over nearby noise. Annoyed by cell phone users who believe they need to yell into their mobiles in order to be heard? Such loud and obnoxious talkers may become extinct, thanks in part to the military's need for sure — and sometimes silent — communications.

For years, scientists at the U.S. military's Defense Advanced Research Projects Agency, have been investigating ways to improve radio communications among troopers in noisy environments such as inside a rumbling tank or clattering helicopter.

Under its Advanced Speech Encoding project, DARPA hopes the answer may lie in refinement of so-called "non-acoustic sensors," experimental devices that can pick up a person's voice without a single syllable shouted, spoken or otherwise uttered.

One such device, the Tuned Electromagnetic Resonance Collar or TERC, being developed by a team of researchers at Worcester Polytechnic Institute in Massachusetts uses a unique approach to creating speech from an unspoken voice.
