Encyclopedia entry (1928–1936)
SPEECH ARTICULATION, the combination of movements in the sound-conducting speech apparatus during speech; the sound-conducting apparatus includes the mouth, nose, nasopharynx, and the larynx up to the vocal cords. For each speech sound, there is a specific combination of movements, i.e., a specific articulation. As a motor act, articulation is regulated by the nervous system through the direct action of bulbar nerves as well as higher speech motor centers. Articulation develops gradually, beginning in childhood, and improves over the years; in old age, articulation begins to gradually deteriorate.
