Lecture 7 Flashcards
What differentiates a strained voice from a strained/strangled voice?
The strained-strangled voice has much more tension
What is the difference between aphonic breaks and aphonia?
Aphonic breaks last only the duration of a phoneme or syllable and only occure occasionally in speech. Aphonia is complete loss of voice/whispering
What are some possible causees of aphonia?
bilateral vocal fold paralysis in an open position; badly swollen vocal folds; psychogenic factors
Tremor is alomost always due to ________
neurological disorders involving teh basal ganglia or cerebellum
Tremor can be differentiated from a singer’s vibrato because
it is more irregular and less well-controlled and has greater amplitude
Sometimes tremor can deteriorate into_________ toward the endo of phonation
rythmic voice stoppages
Diplophonia is caracterized by ______ it is primarily due to _____ but also might be due to ________
two frequencies produced simulataneously
unilateral vocal fold paralysis
a large laryngeal lesion (polyp, granuloma) that vibrates independently
Diplophonia is easieast to hear in (connected speech, prolonged vowels)
prolonged vowels
A strained/strangled voice is characterized by __________ it is amost always due to ________
extreme tension and voice stoppages
spasmodic dysphonia, a neurological disorder
or a smooth voice, ____, ________ and ________ must all be in balance
laryngeal resistance
subglottic pressure
airflow
resonant voice is characterized by ___ as well as smoothness
a full quality
In an unforced voice, there is no apparent _______
rension or strain
Consistent hypernasality is characterized by ________ It is due physiologically to _______
excessive nasal resonance on non-nasal speech sounds
a consistently open velopharyngeal port
A denasal vice, on the other hand is characterized by _______ which can be mainly heard in a phonemic context of ______. Its physiological basis is _______
insufficient nasal resonanance
/m/, /n/, /nj/
an occlusion of the velopharyngeal part due to such factors as swollen adnoids, deviated septum, swollen nasal membranes, tumors or other lesions, ect.
The preceding 3 questions dealt with resonance in terms of ______ functioning. However, sometimes resonance characteristics can be related to _____. Specifically, ______ is due to _____, while ______ is due to _____
velopharyngeal
tongue carriage
cul-de-sac or pharyngeal resonance
posterior tongue carriage
juvenile resonance
anterior tongue carriage
What is diplophonisa?
tow pitches produced at one time, indicating two vibrating masses
What is the physiological explanation of diplophonia?
unilateral vocal folds paralysis, iwt the paralyzed fold vibrating more slowly or due to a unilateral mass on one vocal fold that vibrates independently
** easier to hear in a volwel than connected speech**
What is the physiological basis of aphonia?
due to a variety of factors, including bilateral vocal fold paralysis or badly swollen vocal folds that cannot be set into vibration due to their heavy weight
Also psychogenic factors
What is oral resonance?
appropriate resonance, where speech is resonated in the oral cavity
What is pharyngeal resonance, or cul-de-sac resonance?
usually created by posterior tongue carriage adn limited mouth movement. Speech sounds are resonated in the pharyngeal (supralaryngeal) cavity
How is juvenile resonanace or asthenic voice created?
created by excessibely anterior tongue carriage. Speech sounds are resonated in teh anterior part of teh oral cavity
Goofy’s voice is an example of what?
cul-de-sac resononance
