When air pushes out of the lungs and through the larynx, it travels through the vocal cords, which are located within the larynx. As the air passes through, it causes the vocal cords to vibrate, producing sound. The pitch and quality of the sound can be modified by adjusting the tension and position of the vocal cords, as well as by shaping the mouth and tongue during speech. This process is essential for vocalization and communication.
