Artificial throat could someday help mute people 'speak'. Most people take speech for granted, but it's actually a complex process that involves both motions of the mouth and vibrations of folded tissues, called vocal cords, within the throat. If the vocal cords sustain injuries or other lesions, a person can lose the ability to speak. Now, researchers have developed a wearable artificial throat that, when attached to the neck like a temporary tattoo, can transform throat movements into sounds. Source 8z.
A guy at my work had something like this. It was very interesting and unique.
