Document Summary

A vocal sound produced by relatively free passage of the air stream through the larynx and oral cavity. One or more areas of vocal tract narrowing by some degree of constriction. Can happen with jaw, tongue, lips, and/or teeth. Contributes to the movements of the tongue and lower lip. Gets support from the mandible and hyoid bone. Moves food into position to be crushed by teeth. Moves incredibly fast in order to produce speech sounds. Divided into four regions based on the relationship of the tongue to the roof of the mouth. Tip - nearest to the front teeth. Blade/dorsum - below the alveolar ridge behind the tip. Base - starts beneath the soft palate and goes all the way to the roof. Upper and lower lips contribute to speech articulation. The part of the word that is emphasized by: Minimal contrasts are contrasts between two morphemes that differ in only one sound segment.
