How is the respiratory system used for speech and voice production? A complete discussion of this topic would require much more space than this short segment can provide. However, the respiratory system comprises the pulmonary apparatus and the chest wall apparatus. The pulmonary apparatus is made up of the lungs and airways. The chest wall apparatus is made up of the diaphragm, abdomen, and the rib cage. The diaphragm is the primary muscle of inspiration. The abdomen not only produces the volume displacement in the expiratory direction— thereby generating expiratory pressure—it also serves to optimize the function of the rib cage and diaphragm. It does this by favorably positioning the muscles of the rib cage and diaphragm so that they are on a more favorable portion of their lengthtension characteristic. The abdomen also serves as a platform for the rib cage and diaphragm to push against.
