Document Summary

Articulation: process of joining two elements together, articulation for speech. 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. 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 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. Teeth, hard palate, alveolar ridge of the maxilla. Lower jaw of face: paired maxillae. Make up most of the root of the mouth. Involved in clefting of the lip and hard palate: nasal bones. Form upper margin of the nasal cavity: palatine bones.
