Although some people claim their mouths operate independently of their brains, that's not usually the case. The brain sends neurological signals to the larynx, which converts them into sound. Now, what if we could use those larynx nerve signals to control things?
That's exactly what a company called Ambient is doing. Its Audeo technology basically converts "unspoken speech" (neurological signals flowing through larynx nerves when a person thinks about speaking) into control commands that can be used to guide a motorized wheelchair (video above) or synthesize speech. Pretty amazing!
