aerodynamic theory

generally accepted theory that the vibration of the vocal folds in phonation is produced by the flow of exhaled air past lightly approximated vocal folds; opposed to the now untenable concept that vocal fold motion in phonation results from contraction of the intrinsic muscles of the larynx at the frequency of the vocal fold vibration.
