Document Summary
A branch of linguistics that studies sounds of human speech. Most sounds are produced when air moves out of lungs. There are sounds produced with breathing in which is ingressive airstream mechanism. In english and most languages, egressive airstream mechanisms are air moving out of lungs. The muscles responsible for forcing air out of the lungs are: The air travels from the lungs up the trachea. The voice box consists of muscle and bones. Vocal folds are muscles within the larynx. They can be relaxed, vibrating, or closed. Subglottal pressure must be sufficient to sustain vocal fold vibration. The back part moves, but the front one doesn"t. Air travels through the vocal folds/voice box. Vocal folds vibrate at a fundamental frequency of 10-250 hz. Lips can be rounded during the articulation of some sounds. These articulators allow for a diverse set of speech sounds (or phones). Speech involves a sequence of (sometimes concurring) articulatory events.
