Question

Vocal cords vibrate in the production of voiceless sounds.

Answer 1

When air moves up from the lungs through the vocal tract, it first must move through the larynx, which is sometimes referred to as the voice box. ... When the folds are closed and vibrating, we say the sound produced is a voiced sound. When they are open and stationary, we say the sound is unvoiced or voiceless.
