Assessment Speech Sound Production Flashcards
assessment of SS production consists of
- case history
- standard/NR assessments
- oral mech
- intelligibility
- severity rating
assessment of speech production includes
- consonant, consonant clusters, vowels and diphthongs, polysyllables, prosody, inconsistency
- stimulability, phonetic inventory
assessment of intelligibility
- determines presence of SSD, need for intervention, whether intervention is effective
- not the same as accuracy
- cannot be adequately measured with an articulation test
- ideal: samples with multiple listeners, settings, and contexts
intelligibility is not the same as accuracy
4 y/o is fully intelligible, but still makes some speech sound errors
single-word intelligibility measure
- low contrast = everything sounds the same
- listener: transcription or multiple-choice
- preschool speech intelligibility measure (PSIM)
preschool speech intelligibility measure (PSIM)
- SLP provides stimuli item and child repeats
- listener guesses word from list of phonological similar words
- quantifies intelligibility at the single word level
intelligibility at the word and syllable level
- syllables perceived as understood (SPU) aka: percent of intelligible correct syllables (PICS)
- calculate the percent syllables understood
- a good choice for, “…those tricky, unintelligible kids where you can’t tell where their words begin and end, this can be a useful way to get an accurate, valid measure of their intelligibility.”
intelligibility at the level of connected speech
- collecting an informal (aka: spontaneous) speech sample
- can also analyze SODA, phonological processes, PMV patterns, and generate phonetic inventory
collecting an informal speech sample
- play-based
- multiple
- narrative
- record, transcribe, generate percentage of intelligibility
play-based
- open-ended questions
- narrative the characters
multiple informal
settings/days/listeners
narrative informal
past personal events
measures of intelligibility at the level of connected speech: context scale
- rating scale for parents
- intelligibility in range of contexts outside of clinical setting
- free in 60 languages
severity rating, percent consonants correct (PCC)
- aides in dx of children with suspected phonological disorders (including Spanish-English bilingual children)
- list > conversation: ideally 75 words
- also can be used to measure progress in kids with phonological disorders and cleft
- PCC = (# of consonants correct/total # of consonants) x 100
elements of assessment of speech production
- consonants
- consonant clusters
- vowels
- diphthongs
- polysyllables
- prosody
methods of assessment of speech production
- connected speech
- single word
- stimulability
- phonetic inventory
connected speech method of assessment of speech production
- spontaneous speech samples
- measure of inconsistency
single word method of assessment of speech production
- isolated consonants
- clusters
- vowels and diphthongs
- polysyllables
spontaneous speech sample
- preferably includes 100 different words, picture naming, and 50 words of spontaneous speech
- consider suprasegmentals
- SODA
- phonological processes and PMV patterns
assessing inconsistency in school-aged children: Buy Bobby a Puppy
- “If at least one production of BBP is different, the child is considered inconsistent on this task, which can contribute to their differential diagnosis…”
- “Our friend Bobby is walking through the park with his parents. He sees an animal shelter selling puppies and he really wants one. We should tell his parents to buy Bobby a puppy! We are going to hear the man at the shelter tell Bobby’s mom to buy Bobby a puppy and then it is your turn to say it 5 times in a row! Just repeat what the man says 5 times!”
- “Aw man! Bobby’s moms are still not sure about it! Let’s take turns telling them to buy Bobby a puppy. After the man at the shelter says buy Bobby a puppy, it is your turn to repeat what he says! He will say it 5 times and you repeat it each time your hear it.”
- (Holding up fingers to count or saying “again” are good ways to get the child to keep going.)
assessment of consonant clusters
- most commercially-available assessments do not comprehensively sample all consonant clusters
- Powell (1995): screening for consonant cluster production
most commercially-available assessments do not comprehensively sample all consonant clusters
GFTA: 11 word-initial consonant clusters, 0 word-final clusters
Powell (1995): screening for consonant cluster production
- 34 word-initial clusters
- 30 word-initial clusters
assessment of vowels and diphthongs
- vowel errors usually secondary to severe SSD, CAS, dysarthria, (undetected) HL
- single-word assessments that specifically target vowels
- comprehensive assessment of vowels and vowel inventories can’t be obtained when using a single-word speech assessment
