Title: Anatomy and Physiology of Voice Production: The Phenomenal Voice
Abstract: This chapter discusses the anatomy and physiology of voice production. The original nature of the larynx is entirely at variance with the faculty of speech. The primary function of the larynx is that of a valve of the pulmonary air tract by virtue of the sphincteric action of its muscular folds. The larynx is composed of a number of cartilages, connected by ligaments, and moved by muscles. The muscles can move the larynx as a whole in relation to its adjacent structures, extrinsic muscles, and the cartilages themselves in relation to each other, intrinsic muscles. The pitch of the tone is determined by the length and tension of the vibrating segments of the cords, the configuration of the contact areas of the cord edges, and the air pressure. The length and tension of the cords are controlled by the thyroarytenoid muscles and indirectly by the cricothyroid muscles. It is found that the latter are involved in production of high pitched tones, above 650 Hz.
