What are the three main vocal parts involved in creating sound?

• A. Air supply; Vibrator; Resonator
• B. Air supply; Vocal folds; Resonator
• C. Diaphragm; Larynx; Tongue
• D. Airflow; Glottis; Pharynx

Answer: (A)

Sound production relies on a flow of air, a vibrating source, and a shaping resonator. The air supply from the lungs provides the energy that drives sound. The vibrating source, the vocal folds, turns that stream of air into sound waves by rapidly coming together and moving apart. The resonator, the vocal tract (throat, mouth, and nasal cavities), then shapes and amplifies those waves into recognizable voice sounds. That combination—air supply, the vibrating source, and the resonator—is why the option with air supply, a vibrator, and a resonator is the best match. The other choices mix components that aren’t the primary sound-producing parts (for example, articulation like the tongue or diaphragm functions and glottal control that isn’t the sound source itself).
