Speech detection sans microphones


New Scientist is reporting that a number of research organizations are working on methods for detecting speech without the use of microphones.  Very interesting technology and worth a read if you’re interested in speech recognition like me.

One system, being developed for DARPA by Rick Brown of Worcester Polytechnic Institute in Massachusetts, relies on a sensor worn around the neck called a tuned electromagnetic resonator collar (TERC). Using sensing techniques developed for magnetic resonance imaging, the collar detects changes in capacitance caused by movement of the vocal cords, and is designed to allow speech to be heard above loud background noise.
