Module 8 Flashcards
Phonation 2/26 Part 2
-Focus of vibration of our vocal folds
-Through a contraction , the velocity of the flow increases , causing a decrease in pressure
Bernoulli Effect
The Translaryngeal Pressure allows airflow going through the _____
Larynx
The Laryngeal Opposing Pressure brings the v.f ______
together
List the Vocal Fold Vibration
First the V.F , Start closed because of Laryngeal Opposing Pressure
- Column of air pressure moves upwards towards V.F. in closed position
2/3. Column of air pressure opens at the bottom vibrating layers of V.F. Body of the V.F. stay in place
4/5. Column of air (Translaryngeal Pressure) continuous to move upwards, now towards the top of V.F. and opens the top
6-9. The low pressure created behind the fast-moving air column produces a “ bernoulli effect “ which cause the bottom to close , followed by the top
- CLosure of the V.F. cuts off the air column and release a pulse of air
Attack
—the process of bringing vocal folds _________ to begin phonation (adduction)
together
simultaneous vocal attack
-________ adduction and onset of respiration
coordinate
breathy vocal attack
—starting significant airflow ______ adducting the vocal folds
before
glottal attack
-adduction of the vocal folds occurs ________ to the airflow
prior
What is abducting the vocal folds out of the airstream ( bring them apart )
Termination
What is maintaining the V.F. in place ?
Sustained Phonation
vertical mode of phonation—the vocal folds open and close from ________ to ________
infeior to supeior
horizontal mode of phonation—vocal folds also tend to open ____________ to ____________
posterior to anterior
The minimum driving pressure of the vocal folds in modal phonation is about ______________ cm H20 subglottal pressure.
3-5
Optimal Pitch- the pitch of vocal fold vibration that is ______ for an individual
Optimal
Habitual Pitch- the frequency of vibration of vocal folds that is ______________ used during speech (normal)
habitually
