Swallowing SwallowingYour larynx will, particularly in classical singing, rise during performance. When you stop singing your larynx will not immediately return to its lower resting position: the optimum height for speaking. Speaking whilst the larynx is in the wrong position/height can cause vocal fatigue. It is similar to trying to pull off in a car in second gear. A quick swallow will pull your larynx back to speech position. Swallowing also promotes a sensation of hydration as the vocal folds secrete mucus.Hydration
Slack folds (also known as glottal fry/creak)
There are loads of examples of this on YouTube if you don’t know what slack folds/fry/creak is. The benefits of performing the creak regularly is that is it relaxes and loosens your vocal folds and, for me, provides a sense of the voice being refreshed. Similar to the swallow, slack folds will help reset your larynx to speech position and calm your voice down after performance. On an Estill course that I attended some years ago, the presenter likened the creak to gently shaking the creases out of a duvet cover (the duvet being your vocal folds of course).
