Anatomy and Physiology of Speech Speech production is the result of the manipulation of airflow by the muscles of respiration, the larynx and the muscles of the oral cavity such as the tongue, the lips and the soft palate as they are compressed against the fixed structures within the oral cavity. Production of words in the human being involves multiple organs including the lungs, the respiratory muscles, the larynx, the mouth, the tongue and the pharynx. Based on findings from research done in the early 20th century, Guthrie (1938) described the vocal mechanism as being composed of respiration, phonation and articulation which is associated with resonance. According to Guthrie (1938) two resonators of phonation are the mouth and the...The end:
.....s. Respiration forces airflow through the larynx which vibrates under the Bernoulli principle modifying the sound and resulting in phonation. Articulation of this speech sound occurs in the oral cavity with the muscles of the tongue, lips and palate. To pronounce the different conconants and the vowels in a two syllable word such as ‘mono’ all the three separate processes have to occur to result in the production of the sound that is recognized as the word ‘mono’.
