NASA scientists are developing a speech recognition system that is amazingly capable of understanding and relaying words that haven"t been said out aloud. That means now you can speak your mind out "literally" with the help of an amazing technologyThe technology could one day be used for communication in high-noise environments or in "silent" cell phone calls or in areas where one cannot speak out loud (Hospital theater, movie theater, meetings, etc..) or could be used by firefighters where communication is hindered/disturbed due to background noise.
In the new system, electrodes are attached to the throat for detecting biological signals, similar to what occur for a person reading or talking to him or herself. The signals, thus received, can then be converted into text or synthesized speech.
