Vocal cord

The vocal cords are one group of the features of the human larynx responsible for the production of sound, including speech. They work like a reed instrument, vibrating and modulating the flow of air being expelled from the lungs.

Structurally, the vocal cords are a pair of flaps, resembling the valves of the heart, on either side of the larynx. Their tension and shape can be adjusted by muscles.
