Quiz 8

Question 1

What is the greatest influence on formant frequencies?

Answer 1

vocal tract configuration

Question 2

source

Answer 2

harmonics

Question 3

filter

Answer 3

vocal tract configuration

Question 4

narrowband filter

Answer 4

slow sampling rate - blurred over time - clear harmonics

Question 5

wideband filter

Answer 5

fast sampling rate - filter - clear time- blur harmonics- clear formants

Question 6

Phonation Threshold Pressure(PTP)

Answer 6

the minimum amount of subglottal pressure needed to set vocal folds into vibration(MEAD)

Question 7

external feedback

Answer 7

slowest
visual- tactile- auditory

Question 8

internal feedback

Answer 8

fastest

Question 9

proprioceptive feedback

Answer 9

real time muscular tendon feedback

Question 10

inflamed vocal folds

Answer 10

mass increases - Psub decreases fundamental frequency

Question 11

Greatest influence of harmonic spacing

Answer 11

source (F0)

Question 12

Constricted non-phonated laryngeal sound source

Answer 12

fricative (h)

Question 13

non phonated

Answer 13

Voiceless

Question 14

obstructed supra-laryngeal

Answer 14

voiceless stop

Question 15

obstructive

Answer 15

transient, stop , plosive

Question 16

phonated laryngeal sound source with open velopharyngeal port

Answer 16

nasal

Question 17

sonorant

Answer 17

periodic
harmonics
formants
change of 12dB

Question 18

supralaryngeal sound source

Answer 18

obstruent

Question 19

constricted supra laryngeal phonated laryngeal

Answer 19

voiced fricative

Question 20

phonated

Answer 20

voiced

Question 21

constricted supralaryngeal

Answer 21

fricative

Question 22

Transillumination

Answer 22

measures valving integrity
- light will not pass if valve is completely shut

Question 23

Video Strobscopy

Answer 23

measures mucosal wave with strobe light

Question 24

mucosal wave

Answer 24

vertical phase of MEAD
bottom up

Question 25

palatography

Answer 25

measures contact between tongue and palate

Question 26

laryngoscopy

Answer 26

visual examination of the larynx uses natural light to view structure (tumors/cancer)
views function (adduct/abduct)

Question 27

closed loop

Answer 27

monitoring is built into process

Question 28

open loop

Answer 28

independently producing and monitoring

Question 29

velopharyngeal port insufficiency

Answer 29

impacts obstruent’s (stops, fricatives, affricates)

doesn’t impact nasals

vowels are hyper-nasal

Question 30

VPI can result in unintelligible speech because of…

Answer 30

lack of intra-oral pressure on obstruent’s

Question 31

electromyography

Answer 31

putting an electro-signal over muscle group to measure activation (stimulation) of muscles

surface, hook-wire

Question 32

Electroglottalgraphy (EGG)

Answer 32

measures glottal contact

“electric fence with vocal folds”

Question 33

Electroencephalography (EEG)

Answer 33

recording the electrical activity of the brain via electrodes on the scalp (cap, whole head)

Question 34

Magnetoencephalography (MEG)

Answer 34

mapping brain activity by measuring magnetic fields produced by brain’s electrical currents

Question 35

MRI (magnetic resonance imaging)

Answer 35

is a brain imaging technique that detects magnetic changes in the brain’s blood flow patterns.
measures structure

Question 36

fMRI (functional MRI)

Answer 36

is a functional neuroimaging procedure using MRI technology that measures brain activity by detecting changes associated with blood flow.

Question 37

PTP

Answer 37

infers VF health and change in VF health
ipipipipi
can’t replicate results well

Question 38

harmonic spectrum

Answer 38

whole number multiples of Fo
