Document Summary

The following terms and concepts were taken from assigned chapters in the owens, Test questions will also be taken from class lectures. Chapter 3: overview of the anatomy and physiology of the speech production. Inspiration: contraction of the diaphragm -> expansion of the rib cage -> expansion of the lungs -> increase in lung volume = lower alveolar pressure than atmospheric pressure, thus drawing in air. Expiration: decrease in size of rib cage (recoil pressure) -> compresses the lungs. > increases alveolar pressure -> air rushes out of lungs to achieve equilibrium. *does not require muscular contraction, is achieved by gravity and recoil pressure (muscles returning to relaxed state: describe the respiratory processes for quiet breathing and speech breathing. Parts: cheeks, tongue, jaw, velum, lips, nasal and oral cavity. Purpose: change the shape of vocal tract, affects resonance generating different sounds. Cycles approach: have multiple error sounds, go through different cycles to address each one.
