Chapter 3 Exam 1 Flashcards
systems of speech
Respiratpry, phonatory, resonatory, articulatory, nervous system, auditory
Egressive
sounds are produced with a flow of air that moves outward from the lungs (exhalation)
Ingressive
Sounds produced by the flow of air moving inward
Consonant production
mobile and immobile articulators serve as valving points
vowel production
open vocal tract with llingual adjustments
respiratory adjustments influence?
pauses, variations in pitch, and inflection
breath group
sequence of syllables or words produced on a single exhalation
what happens during inhalation?
diaphragm contracts and its lowered, thoracic cavity expands to allow lungs room to expand, external intercoastals work during inhalation,
what triggers the process of inhalation and exhalation?
pressure differences
what happens during exhalation
Diaphragm relaxes and rises, lungs deflate thoracic cavity space decreases,
Air moves from the lungs into the trachea and up to the level of the larynx which causes the VFs to vibrate.
Speech cycle while we speak
10%inhalation
90% exhalation
What connects the lungs to the larynx?
trachea
what happens during adduction?
vocal folds come together to produce voiced sounds
What happens during ABduction
Vocal folds open and produced voiceless sounds
subglottal pressure
air pressure below the vocal folds
Bernoulli effect
causes adduction of vocal folds
increased airflow through vocal folds causes a decrease in air pressure between vocal folds which causes them to ADDUCT.
The pharynx directs airflow to the oral and nasal cavities from where?
larynx
Fundamental Frequency
basic rate of vibration of vocal folds
Habitual pitch
pitch at which a person typically speaks determined by fundamental frequency
Pharynx is divided into three major sections
larynopharynx, oropharynx, and nasopharynx
supralaryngeal
structures above the level of the larynx
