Phonation - Wikipedia
WebThe term phonation has slightly different meanings depending on the subfield of phonetics. Among some phoneticians, phonation is the process by which the vocal folds produce certain sounds through quasi-periodic vibration. This is the definition used among those who study laryngeal anatomy and physiology and speech production in general.

WebJun 5, 2012 · The production of a speech sound may be divided into four separate but interrelated processes: the initiation of the air stream, normally in the lungs; its phonation in the larynx through the operation of the vocal folds; its direction by the velum into either the oral cavity or the nasal cavity (the oro-nasal process); and finally its articulat...
Speech - Voice Production, Acoustics, Physiology | Britannica
WebThe physical production of voice has been explained for a long time by the myoelastic or aerodynamic theory, as follows: when the vocal cords are brought into the closed position of phonation by the adducting muscles, a coordinated expiratory effort sets in. Air in the lungs, compressed by the expiratory effort, is driven upward through the trac...
