In voice production, which component serves as the resonator?

• A. Head and chest cavities
• B. Vocal folds
• C. Exhalation mechanism
• D. Ossicles

Answer: (A)

The main idea here is resonance in voice production. After the vocal folds vibrate to create a sound source, the surrounding air spaces—especially those in the head and neck—act as resonators. The cavities in the head and chest shape and amplify specific frequencies, giving the voice its tone and character. In other words, the sound produced by the vocal folds is filtered and enhanced by these resonant spaces, producing the recognizable qualities of voice.

The other options describe parts that either generate the sound (the vibrating vocal folds) or supply the air (breath mechanism) or belong to a different system (ossicles in the ear), so they don’t function as the resonators in voice production.
