The scientific term for the human voice box is "larynx." It is an important structure located in the neck, situated between the pharynx and the trachea. The larynx is responsible for sound production (phonation), protecting the trachea against food aspiration, and facilitating breathing. It contains vocal cords that vibrate when air passes through them, producing sound. The larynx also plays a role in regulating airflow during breathing and acts as a filtering mechanism for inhaled air, making it essential not just for speech but also for overall respiratory health.
