Q

what is the source-filter theory

A

Source–> The basic source of power for speech is the respiratory system pushing air out of the lungs.
Filter–> The larynx, pharynx, nasal cavity, and oral cavity (= supralaryngeal vocal tract)

Q

what is coarticulation

A

Movements related to sequentially occurring sounds overlap and interact.

Features of adjacent sounds (tongue advancement, etc) affect the production of their “neighbors”

Q

what is the difference between apraxia and dysarthria

A

Apraxia: motor planning disorder which the brain can’t coordinate speech movements

dysarthria: motor speech disorder caused by weak muscles which affects phonation

Q

articulatory characteristics of cleft palate

A

glottal stops _vf don’t get pushed together

nasal fricatives; talking through nose bc air way is abnormal

16
Q

which types of consonants are the most difficult to pronounce with cleft palate

A

dentals, labials, and palatals

17
Q

four valves of vocal tract

A

labial valve, lingual valve, velopharyngeal valve, and laryngeal valve

18
Q

what is the overlapping effect of one articulatory movement on another

A

coarticulation

19
Q

how are /m/ and /b/ sounds different

A

/m/ - open velum
/b/ - closed velum

20
Q

articulation of stuttering

A
  • longer vocal durations
  • larger jaw, lip and tongue movements
21
Q

what are the factors that may affect a speaker’s intelligibility

A

rate, voice, and precise articulation

22
Q

what are the ways we categorize consonants

A

place, manner, and voicing

23
Q

how do coarticulation and segmental features contribute to spoken language

A

connected speech is smooth, and able to produce clear segments of speech

24
Q

what is velopharyngeal speech

A

disorder, excessive resonance in speech disfunction

25
Q

what is another name for velopharyngeal inadequacy

A

velopharyngeal dysfunction

26
Q

what are the four important features of the vocal tract resonator

A

pharynx, nasal cav., oral cav., and epilaryx

27
Q

explain the difference between hyper nasality and hypo nasality.

A

hyper- occurs when too much sound resonates in nasal cav during speech

hypo- reduced nasal resonance with blockage or obstruction

hyper example- found in different consonants
hypo example- talking with stuffy nose

28
Q

explain f1 and f2 plots

A

F1 on the horizontal axis cor-responding to tongue height

F2 on the vertical axis relating to tongue advancement.

which means that the higher the vowel (like /i/ and /u/) the lower the F1 value. For F2, the typical pattern is that front vowels (like /i/ and /ae/) have higher values than back vowels.

29
Q

what is the difference between resonance and articulation

A

resonance- throat, mouth, nasal passage
articulation- sound changed by tongue, soft palate, and lips

30
Q

ultrasound

A

non invasive
provides image of structures

31
Q

Electropalatography

A

visual feedback of position of tonguge, real time information

32
Q

glossometry

A

calc the distance between tongue and sensors every 10ms

33
Q

optopalatography

A

updated form of glossometry

measures light reflected from tongue, pressure and location of contact

34
Q

cleft palate resonance

A

hyper nasality

35
Q

hearing impairment resonance

A

hypernasality
