Document Summary

The vocal tract and the production of speech. The production of speech begins in the lungs, which provide the airstream for vocalization. Vocal tract is the region where speech sounds are produced. Has 3 open cavities: nasal cavity, oral cavity, and throat (or pharynx) We change the shape of the vocal tract in various ways to create different sounds. Pair of membranes stretched across opening of glottis (voice box) Place of of articulation is the location in oral cavity where air flow is obstructed to produce consonants. Bilabial (bi means two and labial means lips) -> m, b, p. Labiodental (labio means lip and dental means teeth) -> f, v. Interdental (inter means between and dental means teeth) -> th. Manner of articulation is the degree to which airflow is obstructed in production of consonants. Voice onset time (vot) -> voiced (early vot) and voiceless (late vot) Jaw: continuum from high (open) to low (closed)
