Document Summary

Articulation- the process of joining two elements together: articulation for speech. The process of bringing two or more moveable speech structures together to form the sounds of speech. In the oral cavity, the undifferentiated buzz produced by the vocal folds is shaped into phonemes: source filter theory of vowel production. Describes how the oral cavity shapes speech. States that a voicing source is generated by vocal folds, routed through vocal tract, and then shaped into sounds of speech. Vocal tract consists of the oral cavity, pharynx, and the nasal cavity. This linkage provides the variable resonating cavity that produces sound: articulators. Structures used to produce sounds of speech. Tongue, mandible (lower jaw), velum (soft palate), lips, cheeks, pharynx, larynx, and hyoid bone. Teeth, hard palate, alveolar ridge of the maxillae (upper jaw: facial bones. Involved in clefting of the lip and hard palate. Make up most of the roof of the mouth.
