CAS and ISSD Flashcards
what does ISSD stand for?
inconsistent speech sound disorder
what is ISSD believed to be?
not a phonetic planning or implementation problem BUT a problem w/ phonological assembly/planning
what are the key characteristics of ISSD?
inconsistent errors in the absence of CAS
increasing errors w/ increasing length
wrong choice of phoneme rather than order errors
better imitation, worse spontaneous speech
oral motor WNL
no groping or silent posturing
normal speech and DDK’s
what is CAS?
childhood apraxia of speech
motor speech disorder; difficulty planning to move parts needed for speech
children with CAS have problems with —- , —–, and —–
sounds
syllables
words
what are the key characteristics of CAS?
inconsistent errors
difficulty making smooth transitions
inc errors, inc length
better spontaneous speech, worse imitation
poor sequencing of sounds
groping and silent posturing
slow speech and DDK rates
what characteristics do ISSD and CAS have in common?
inconsistent errors
inc errors and inc length
what are some key cautions with diagnosing CAS?
CAS is rare
there is frequent over identification
need some speech for diagnosis
controversial so can say “consistent with CAS”
CAS may potentially have —- ——- characteristics and ——– suprasegmentals
non-speech
atypical
what are some examples of atypical suprasegmentals that may be present in CAS?
atypical prosody
pauses between phonemes, syllables, and words
irregular pitch and resonance
what are examples of non-speech characteristics that may be present in CAS?
oromotor difficulties such as feeding and drooling
fine motor difficulties
what are the 3 key features of CAS?
articulatory accuracy
syllable transition
lexical stress
