VOCAL ASSISTANCE: Artificial throat could someday help mute people’speak’

摘要

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 reporting in ACS Nano have developed a wearable artificial throat that,when attached to the neck like a temporary tattoo,can transform throat movements into sounds.
