In the June 2004 issue of Scientific American, there was a small article about an experimental system for interpreting unspoken "speech":

It seems that this could even be of benefit to divers with typical regulators not just full-face masks. Since the SEARCH function didn't turn up any discussion about this, I was wondering how well this might be received (when it's practical and reasonably priced, of course).Scientific American:If noise, injury or a thin atmosphere ever gets in the way of conversations between future astronauts, a NASA technology that recognizes unspoken words may come in handy. The tongue and vocal cords may not move when speaking silently, but they still receive speech signals. To pick up those signals, Chuck Jorgensen of the NASA Ames Research Center placed button-size sensors under the chin and on the neck of three subjects. A computer program recorded electrical activity whenever it rose above background noise and learned to associate the signals from an individual speaker with one of about 20 different words nearly 90 percent successfully, Jorgensen claims. By silently mouthing numbers, subjects browsed the Web without a keyboard. Hazmat crews, divers and the handicapped may benefit from subvocal speech recognition, says Jorgensen, whose findings were announced by NASA in March.
