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

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.
