This article explains about the voice recognition software that interprets what we are going to say even before we say it. NASA scientists have had an early success in developing a prototype technology that recognizes and processes silent speech for use with a PC. Instead of grabbing words from spoken sounds, the technology grabs words from nerve signals the human brain sends to the throat and tongue. Stick-on sensors are used to intercept the brain signals. The signals are amplified, and differentially measured.
