What does the larynx primarily function as?

The primary function of the larynx is to produce speech, which involves the creation of sound through the vibration of the vocal cords located within it. The larynx serves as a key component in the phonation process: when air is exhaled from the lungs, it passes through the vocal cords, causing them to vibrate and produce sound. This sound can then be articulated into speech with the help of other parts of the vocal tract, such as the tongue and lips.

In addition to its role in speech production, the larynx also has important protective functions, such as preventing food and liquids from entering the airway during swallowing, but its primary identification in terms of function is for producing voice. This distinguishes it from other respiratory structures that have more direct roles in air conduction, filtration, and gas exchange.
