It regulates the inhalation-exhalation cycle for passive breathing: serves as the power source for producing speech. Phonatory system: regulates the production of voice and the prosodic, or intonational, aspects of speech. Resonatory system: related to vibration of the air as it flows from the pharynx into the oral or nasal cavities, velopharyngeal port the opening between the velum and the back of the pharynx wall. Articulatory system: regulates the control of the articulators within the oral cavities to manipulate the outgoing airflow in different ways, usually at very high speeds. Articulatory/resonating system: also called the vocal tract, begins at the vocal folds and includes the oral, nasal, and pharyngeal cavity.
