NASA’s research on subvocalization technology is moving forward. Their system intercepts nerve signals to the vocal cords before the speaker makes a sound and then figures out what words they signify. This technology will enable people to speak silently on the phone or to their computers, without moving their lips or making a sound. It’s almost telepathy. I blogged about this last year when it first came out. It’s actually a technology I dreamed about a while back — "silent speech" is one of those things that has to happen in order to truly free humans from keyboards (although I must confess, I love to type).
