Yes, humans have a voice box, also known as the larynx.
The larynx is a vital organ located in the neck with several critical functions, including breathing, swallowing, and most notably, voice production. The voice production function occurs because of the vocal cords located within the larynx. Air passing through the vocal cords causes them to vibrate, which creates sound waves. These sound waves then resonate in the pharynx, nose, and mouth, resulting in the production of speech and other vocalizations.
