The âfalseâ vocal folds or cords are placed above the real vocal cords and prevent the substances like food from entering inside trachea while we are swallowing it. They are not in any way related to the function of singing or speech.
The Vibrator: The larynx (or voice box) sits on top of the windpipe. It contains two vocal folds (also known as vocal cords) that open during breathing and close during swallowing and voice production. When we produce voice, the airstream passes between the two vocal folds that have come together.
