Document Summary
Respiratory system as power supply, develops relatively constant pressures that are used to create vocal fold vibration as well as momentary changes in pressure required for linguistic stress. Pressure developed by the respiratory system is the primary determiner of overall speech loudness. Larynx as sound generator, or source of sound, produced by vocal fold vibration; phonation is the term referring to the act of producing speech sounds with the periodic vibration of the vocal folds. The vocal folds vibrate at different rates for men, women, and children, and their rate of vibration determines the pitch of the voice. Vocal fold vibration also important for conveying linguistic stress and emotional states: know the higher the vibration the higher the pitch in the vocal chords. Vocal tract as the shaper of the sounds produced by the vocal folds; the vocal tract shapes this sound into the individual elements we call the sounds of speech.
