talk without talking
Invented by Michael Callahan: Three pill-size electrodes on the throat pick up electrical signals generated between the brain and the vocal cords. A processor in the device then filters and amplifies the signals and sends them to an adjacent PC, where software decodes them and turns them into words spoken through the PC’s speakers. By placing the electrodes on the neck and “speaking” silently through vocal-cord movements (but without moving the mouth), the wearer generates enough neural activity to trigger this chain of events.
Audeo is capable of more than just giving a voice to those physically impaired though. It could be used to speak on the phone without ever actually vocalizing anything, opening up the possibilities to fantastical spy or military applications. That and it could one day get rid of that is-he-talking-to-me-or-someone-on-the-phone confusion around people wearing BlueTooth headsets.
