Bernoulli principle

In the phonetics, Bernouilli principle refers to an aerodynamic principle involved in vibration of the vocal folds.

Comments

Air pressure from the lungs opens the glottis during each vibration. The folds come together again during each vibration because of their inherent elasticity and the sudden pressure drop between the folds as the air streams through the open glottis.
