Document Summary
Exam 2, next thursday (3/29), in test center. The study of how sounds are produced. Consonantal sounds: constriction of airflow in vocal tract. Vowel sounds: little to no obstruction of airflow in vocal tract. Manner of articulation: how sound is constricted. Every vowel is a combination of these 4 features. [i] as in meet is high front tense unrounded vowel. [ ] as in pat is low front lax unrounded. [ ] as in pot is low back lax unrounded. [u] as in buzz is high back lax rounded. These systems are at work before the actual sound is produced; they help to plan out the motor movements. The primary motor cortex is located in the rear portion of the frontal lobe. The primary motor cortex works together with the premotor cortex, the supplementary motor area, posterior parietal cortex, and subcortical brain regions, to plan and carry out motor movements.
