Anat of Articulation - Bone ID's Flashcards
vocal tract composed of these three
mouth, pharynx, nasal cavity
what is the source-filter theory?
Output of sound = acoustic source (VF) + a filter (vocal tract)
what is the difference between mobile and immobile articulators?
mobile can move around (ie tongue) and immobile can’t (ie teeth)
Jaw bone
mandible
according to source-filter theory, the ____ the volume of the resonator, the lower the frequency

inf. nasal conchae
Articulate with maxilla, palatine, ethmoid
