Normal Voice Production
Voice production is dependent on the interrelationship of many different physiologic components. These voicing components include respiration (your breath or power generator), phonation (your larynx or sound source), and resonance (your throat, tongue, teeth, jaw, or the filter above the vocal folds), as well as the psychophysical components of pitch, loudness, and rate.
It is expected that if something interferes with the appropriate balance of these systems, the other components would be modified. Also, if you consistently misuse any component or combination of components of voice production it may cause a laryngeal pathology.
