What is the function of the larynx in speech?

• A. To enhance the volume of the voice
• B. To house the vocal cords and facilitate phonation
• C. To modify pitch during speech production
• D. To act as a filter for sound produced

Answer: (B)

The larynx plays a pivotal role in speech production primarily by housing the vocal cords (also known as vocal folds). It is situated in the throat and acts as a gateway between the trachea and the esophagus. The primary function of the larynx during phonation is to allow the vocal cords to vibrate when air from the lungs is pushed through them. This vibration generates sound, which is then shaped into speech by the articulators (such as the tongue, lips, and palate).

While the larynx does play a role in modifying pitch and can affect volume, its fundamental purpose in speech is centered on the production of sound through the vocal cords. The shape and tension of the vocal cords can be adjusted, which alters the pitch of the sound produced, but this is a secondary aspect of its overall function. The larynx does not function as a filter for sound; rather, that role is performed by other structures in the vocal tract, such as the throat, mouth, and nasal cavities, which modify or filter sounds into discernible speech.
