Phono Final Flashcards
What questions do we want to ask when doing an appraisal?
Why are we conducting the assessment?
What information should we collect?
How should we collect the information
What are the two parts of an assessment?
appraisal, diagnosis
What are screenings?
brief observation of speech sound production
what are formal screenings?
standardized, valid, reliable
What are informal screenings?
ask children to state name, age, address, etc; ask older children and adults to read a passage
what are the components of an assessment?
case history single-word speech sample stimulability testing spontaneous speech sample oral mech hearing screening language screening specific auditory perceptual testing cognitive appraisal
What are the ways to score a single-word speech sample?
two way - production is correct or incorrect
five way - determine whether Substitution, Omission, Distortion, or Addition
phonetic transcription - describe actual speech sound
How long does a spontaneous speech sample have to be?
3 minutes, or 200-250 words
When would you use specific auditory perceptual testing?
client demonstrates collapse of two or more phonemic contrasts into a single sound
How do we need to organize data for diagnosis?
document inventory and distribution of speech sounds
How do we know when a disorder is ARTICULATION
phoneme contrasts maintained, peripheral, motor-based problems
How do we know when a disorder is PHONOLOGY
loss of phonemic contrasts
What are the types of analysis of phonological error patterns?
place-manner-voice analysis (feature system)
phonological process analysis
assessing productive phonological knowledge
What are the general guidelines for intelligibility?
50% intelligible by 2 years
75% intelligible by 3 years
90% intelligible by 4 years
what are factors that influence intelligibility
loss of phonological contrasts
loss of contrasts in specific environments
degree of homonymy
differences between target and speaker’s production of target
frequency of error sound
consistency of error production
familiarity of listener with speaker’s speech
context in which communication occurs
what is the severity measure people use?
Percept of consonants correct (PCC)
Consistent errors are more indicative of _____
articulation disorders
What should you look at during a phonological assessment?
inventory of speech sounds
distribution of speech sounds
syllable shapes and constraints
What is a central goal of assessment?
understanding the child’s phonological system
What constitutes a severe phonological disorder?
6 (i’m guessing consistent) sound errors over 3 manner classes
What are the characteristics of a child with emerging phonology?
demonstrates small expressive vocabulary
reduced repetoire of consonants and syllable shapes
unintelligible
may have other language difficulties
may show specific delay/disorder in communication skills
may have been born with a devleopmental disorder
may exhibit an early acquired disorder secondary to disease or trauma
may belong to group of late talkers whose expressive language emerges slowly
What are some modifications to the case history you can use?
questionnaires
What are some modifications to single-word speech sound sampling you can use?
use toys and objects, ask caregivers to keep a log of words, encourage sound play and sound imitation
What are some modifications for spontaneous speech sound sampling?
ask caregiver to play with child
modifications for oral mech?
pretend to make fish or clown faces, have child look in your mouth first with flashlight
modifications for language screening?
use language sample
modifications for cognitive appraisal?
play behavior
We usually consider a child’s sound system to be:
unique self contained system; independent of adult sound system
how do you usually determine severity?
clinical judgement scales or percentages
What are frequent errors that lead to unintelligibility?
difficulty with liquids, stridents, clusters,
sometimes: deletion of entire sound classes
ERRORS OFTEN NOT CONSISTENT
How might you get a speech sample from a highly unintelligible child?
use scripts and structured activities (trip to mcdonald’s, telephone conversation), gloss utterances that may be difficult to understand later
