Document Summary

Articulation: process of joining two elements together. Adjustments of the shape and coupling of cavities along the vocal tract. Resonant characteristics contingent on strength, shape, length, density of vibrating material absorbing, reflecting, refracting. Vocal tract: fundamental f and harmonics (vibratory rat of folds) race through tract and encounter a series of valves changing volume/shape of resonating cavities. The amount of space and configuration of that space anterior to the point of constriction are variables that shape the acoustic signal: vocal tract lengthened, formant frequencies decrease, vocal tract shortened, format frequencies increase. Structures: used to produce sounds of speech points of constriction. May be mobile: tongue, lips, pharynx, mandible, velum. May be immobile: teeth, hard palate, alveolar ridge, maxillae. Sinus: a recess of channel: ethmoid- between the eyes, frontal- front (above the eyebrows, maxillary- behind the cheekbones, sphenoid- behind the eyes (bat)
