lecture 26 Flashcards
glottis
space between vocal folds
subglottal region
area below vocal folds
voiceless phonemes or speech sounds
produced without use of vocal folds
voiced sounds produced how
action of vocal folds
phonation
voicing or product of vibrating vocal folds
respiration role in communication
energy source that permits phonation to occur
what two muscles are apart of thyroarytenoid muscle
thyrovocalis and thyromuscularis
thyrovocalis origin and insertion
originates from inner surface of thyroid cartilage and inserts into vocal process of arytenoid
thyrovocalis function
glottal tensor which means it tenses the vocal folds
thyromuscularis muscle origin and insertion
originates on inner surface of thyroid cartilage near notch and inserts into muscular process of arytenoid
thyromuscularis muscle function
laryngeal relaxer; relaxes vocal folds
three properties of vocal folds
elasticity, stiffness, inertia
elasticity
able to return to original state
stiffness
strength of the forces that restore it to original state
inertia
body in motion tends to stay in motion
cycle
moving from one point in a pattern to same point again
period
time it takes to pass through one cycle
periodic
repeats itself in predictable fashion
frequency
how often a cycle of vibration repeats itself
hertz
cycles per second
fundamental frequency
the frequency of vibration of sustained phonation or conversational speech
use what to accurately reflect fundamental frequency
conversational speech or reading tasks
fundamental frequency for males and females
males 80-150 Hz & females 190-235 Hz
elements for changing pitch
mass, tension, length
