What part of the respiratory system produce vocal sounds?

The part of the respiratory system that produces vocal sounds is the larynx, commonly known as the voice box. It contains the vocal cords, which vibrate when air is expelled from the lungs, creating sound. The pitch and volume of the sound can be modified by adjusting the tension and length of the vocal cords. Additionally, the resonating chambers of the throat, mouth, and nasal cavity also contribute to the quality of the voice.
