Document Summary

3 anatomy and physiology of the speech mechanism: primary purpose: breathing, secondary purpose: supporting speech production, preparatory breath: breath taken in before producing speech, more air volume than when at rest. For speech inhalation only takes up approximately 10% of the inhalation-exhalation cycle, while 90% is devoted to exhalation which supports the airstream for speech. For resting breathing inhalation and exhalation each comprise about 50% of one cycle. The lips: open and close in the production of several speech sounds: maxilla: upper jaw, supports the upper lip, mandible: lower jaw, supports the lower lip, bilabial phoneme: sounds produced with both lips (i. e. p, b, m, w) In english, the lower lip is more mobile. Labial: the sounds associated with the lips (i. e. p, b, m, w, f, v) Labiodental: phonemes that involve the articulation of the lower lip and the teeth (i. e. f, v) Ows into the nasal cavity during production (i. e. m, n, ng)
