Phonation
Quick Definition
The production of voiced sound through vibration of the vocal folds, the fundamental acoustic source for speech and singing.
Factual Definition
The quasi-periodic vibration of the vocal folds driven by the interaction of subglottal air pressure, vocal fold tissue properties, and supraglottal acoustic loading. Described by the myoelastic-aerodynamic theory (van den Berg, 1958) and refined by Titze's body-cover model and considerations of vocal tract inertance (Titze, 1988, 2006).
