ANATOMY

Detailed explanation-1: -Vocal cords are stretchy flaps of skin in your throat that vibrate to make a sound. In order to speak, we move air past our vocal cords, which makes them vibrate. The vocal cords must be in good shape for speech to sound clear and loud.

Detailed explanation-2: -When we speak muscles in the larynx bring the vocal cords together. As the air rushes from our lungs out through the larynx, the from portion of the vocal cords vibrate, producing a sound. The upper portion of our throat then modifies this sound to produce speech.

Detailed explanation-3: -When you breathe, the vocal folds are open to allow air to flow from your upper airway into your trachea and lungs. When you want to speak, you close your vocal folds and begin to exhale, causing an increase in pressure that starts them vibrating (cyclic opening and closing).

Detailed explanation-4: -Overview. Vocal cords open when you breathe and close when you swallow and talk.

Detailed explanation-5: -The vocal cord exhibits a reciprocating respiratory motion, abducting in inspiration and returning to the intermediate position in expiration. It is generally agreed that this motion is the result of respiratory activity of the internal laryngeal muscles.
