LECTURE #9 - pediatric speech sound disorders Flashcards

1
Q

how are consonant/vowel sounds classified ?

A

Consonant and vowel sounds are classified based on how and where they’re made in the mouth and throat:

Consonants: Classified by the amount of airflow restriction (like blocking with the lips or tongue) and whether the vocal cords vibrate (voiced or voiceless).

Vowels: Classified by the shape and position of the mouth and tongue, with an open vocal tract and always using vocal cord vibration.

Q

what does “vocing” mean ?

A

Voicing is the process of making a sound by vibrating your vocal cords.

When you produce a voiced sound, like z in “zebra,” your vocal cords are close together and vibrate as air passes through. In contrast, for a voiceless sound like s in “snake,” your vocal cords stay apart, so they don’t vibrate as air flows through.

85
Q

do we usually know or not know the cause ?

A

we usually do not know the cause / functional cause

86
Q

how many theories of pediatric SSD ?

A

3

87
Q

what are the three theories of pediatric SSD ?

A

1) behaviourist
2) distinctive features & natural phonology
3) optimality

88
Q

define the behaviourist theory ?

A
  • acquisition of sounds is rooted in pre-linguisted behaviours (e.g., babbling) and vocal interactions
  • early vocal interactions promote later development
89
Q

define the distinctive features and natural phonology :

A
  • development affected by phonological patterns
  • patterns suppressed as the child learns speech and language
90
Q

define optimality :

A
  • children learn constraints for possible word pronounciations
  • e.g. words don’t begin with /mr/
91
Q

when diagnosing pediatric SSFs, what is significant ?

A

1) is child’s speech different from their peers ?
2) does their speech interfere with communication ?
3) does the child avoid speaking situations ?
