Psychology 2134A/B Chapter Notes - Chapter 4: Alveolar Consonant, Vocal Folds, Vocal Tract
Section 4. 1: the vocal tract and the production of speech. The production of speech begins in the lungs: provide airstream. This airstream flows up the trachea through the glottis aka voice box. Alveolar ridge the fleshy region of the mouth covering the bone where the upper teeth are anchored. Hard palate the bony region along the roof of the mouth. Soft palate or velum the fleshy region behind the hard palate. Consonants are produced by restricting the airflow through the mouth and this can be done at a number of locations. Glottis: a consonant sound produced by constricting the vocal folds is called the glottal stop. The degree to which airflow is obstructed in the production of consonants. Plosive stop briefly pressing your thumb against a garden hose": momentarily stopping and releasing the airflow, voiced plosives b, d, g, voiceless plosives p, t, k, nasal stops m, n, ng. Two manners of articulation create sound through friction.
