Which component corresponds to the vibrator in voice production?

• A. Air supply
• B. Vibrator
• C. Resonator
• D. Diaphragm

Answer: (B)

Sound in voice production starts with a vibrating source—the vocal folds in the larynx. When you exhale, air from the lungs passes through partially closed vocal folds, causing them to stretch, come together, and then blow apart in rapid cycles. This glottal vibration creates the basic sound waves that become voice. The term vibrator here points to that vibrating element, which is the vocal folds themselves. The other components have different roles: the air supply provides the energy for phonation; the resonator (throat, mouth, nasal cavities) shapes and colorizes the sound; and the diaphragm is a muscle that helps control breath. So the vibrating element responsible for producing the sound is the vocal folds.
