Accepted Answer

Sound is normally produced by air moving up through the vocal cords. As air passes through the vocal cords from the lungs, it causes the vocal cords to vibrate, producing sound. The epiglottis does not vibrate to produce sound; it acts as a flap that prevents food from entering the windpipe.
