Voice and Voice Disorders
How the Voice works
The larynx, or “voicebox,” is an organ with two important functions. Part of the respiratory (breathing) system, the larynx closes off during swallowing to prevent entry of foreign material (i.e. food or liquid) into the airway, or aspiration. The larynx also serves to produce voice through complex interactions with the muscles of the abdomen, back and rib cage, lungs, throat, mouth, and nose. During voice production, the vocal folds (or vocal cords) open and close rapidly. Changes in vocal pitch and loudness are accomplished through shortening and lengthening of the vocal folds along with fluctuations in airflow. On average, the vocal folds come together approximately 100 times per second in men; and nearly double that number to women to 220 times per second.
