Inspiratory Phonation occurs when voice is produced using inhaled air. By contrast, normal voice production uses exhaled air. Voice production with inhaled air is often involuntary or unintentional—for example, a gasp of surprise, or with a person whose vocal cords are scarred or paralyzed in a nearly closed position. Inspiratory phonation is also more limited with respect to pitch range and loudness than is normal, expiratory phonation.
Reinke’s (smoking-related) edema and how to see it

Smoker’s Polyps (aka Polypoid Degeneration or Reinke’s Edema)
This video illustrates how smoker’s polyps can be seen more easily when the patient makes voice while breathing in. During inspiratory phonation, the polyps are drawn inward and become easier to identify.
