Csd 315 Quiz 4

Front 1

Vocal tract develops most growth when?

Back 1

between birth and 4 years of age

Front 2

articulators role

Back 2

(1) alter shape of vocal tract, (2) create source of vibrational energy at some point in the tract above the vocal folds

Front 3

Lips biomechanical properties

Back 3

mass- small relative to force available, viscosity- measurable but relatively small, elasticity- very large, muscle- fast twitch

Front 4

mandible biomechanical properties

Back 4

mass- large, lots of inertia, muscle- large & fast

Front 5

tongue biomechanical properties

Back 5

mass-negligible in relation to muscle forces available, viscosity- " "

Front 6

most important articulator

Back 6

tongue

Front 7

hydostat

Back 7

means that displacement in one area results in displacement in another without change in volume, composed mainly of muscles with no skeletal support

Front 8

muscles that depresses mandible

Back 8

digastricus, mylohyoid, genioghyoid, lateral pteroygoid

Front 9

muscles that elevate mandible

Back 9

temporalis, masseter, medial pterygoid

Front 10

what's unique about the elevator muscles of mandible

Back 10

only muscle of the mandible that have muscle spindles, providing feedback to the neuromotor system

Front 11

extrinsic muscles of tongue

Back 11

provide major movements

Front 12

intrinsic muscle of tongue

Back 12

involve shaping of the tongue

Front 13

Elevates tongue tip

Back 13

superior longitudinal

Front 14

depresses the tongue

Back 14

genioglossus (medial) hyoglossus & chonodroglossus (side)

Front 15

deviates the tongue

Back 15

left to right (superior & inferior longitudinal)

Front 16

protrudes the tongue

Back 16

posterior genioglossus

Front 17

retract the tongue

Back 17

genioglossus for retraction into the oral cavity

Front 18

antagonist muscle

Back 18

palatoglossus

Front 19

compare velocity of movement of the tongue and the velum

Back 19

velum- velocity movement strongly affected by phonetic context.

tongue- lingual movement velocity related to distance to be traveled

Front 20

tensor veli palatini

Back 20

muscle of the velum that is not as active during speech, is more for swallowing & opening the eustachian tube

Front 21

purpose of articulator movement of speech

Back 21

to control airflow simultaneously with changing vocal tract shape so that sound stream is created

Front 22

airflow control

Back 22

aerodynamic phenomenon

Front 23

shape control

Back 23

acoustic phenomenon

Front 24

direction & velocity of air movement controlled in vocal tract

Back 24

controlled by changes in airway size

Front 25

sound productions of lips

Back 25

b, p, m, w

Front 26

sound production of teeth

Back 26

f, v

Front 27

sound production of alveolar ridge

Back 27

t, d, s, z

Front 28

sound production of hard palate

Back 28

r, j

Front 29

sound production of velum

Back 29

k, g, n

Front 30

plosive sounds

Back 30

p, t, k

Front 31

resonator

Back 31

anything that vibrates will do so at a natural resonant frequency

Front 32

formant

Back 32

band of frequencies at which vibration will occur with the greatest amplitude

Front 33

what is the vocal tract function in terms of filter

Back 33

vocal tract will function as an acoustic filter because humans have the capacity to modulate which frequencies will be passed through and which frequencies will be attenuated by changing vocal tract

Front 34

high front vowels

Back 34

i

Front 35

low back vowel

Back 35

ae

Front 36

mid front vowel

Back 36

e

Front 37

back vowel

Back 37

u

Front 38

what happens during production of the vowel in terms of tongue movement

Back 38

As the tongue moves up, frequency of F1 goes downand as the tongue moves forward, frequency of F2 goes up.As the tongue moves down, frequency of F1 goes up,and as the tongue moves back frequency of F2 goes down.
