Perceptual Speech Evaluation Goal:
To determine
the impact, on artculatory performance and resonance, of velopharyngeal function problems, fistulas, dental and occlusal deviations and other structural deviations such as large tonsils, large adenoid, nasal obstruction...
-
To accomplish perceptual eval goal we mus
Obtain?
Carefully ?
_____ perceptual speech data with orofacial exam findings?
____ the clinical data?
- an adeqquate speech sample
- analyze that speech sample
- Correlate
- Interpret
-
Protocol for assessment of CLeft Palate Speech Errors:
Obtain an adequate speech sample need: (4)?
- Connected speech
- published sound inventories
- special sampling contexts
- stimulability
-
Connected speech is?
conversation, oral reading of sentences or paragraphs, picture description, automatic speech, word sentence repetition
-
Published sound inventories are?
articulation tests
-
Special sampling contexts are:?
sensitive to cleft type speech errors
-
Special Sampling Context single words?
high pressure consonants
-
Special Sampling Context sentences looking for?
- high pressure consonants (1 target/sentence)
- nasal consonants (loaded)
- low pressure consonants /r,l,j,w/
-
Special Sampling Context "zoo passage" looking for?
- no nasal consonants
- assess for hypernasality
-
High pressure consonants in UPS?
/p/ /f/ "sh" /g/
-
Low pressure consonants in UPS?
/w,l,r,h/
-
Special Sampling Context also checks?
- CV syllables
- serial counting (60-66, 50-56)
- high vowels (isolation and words with HPCs for hypernaslity)
- Words with nasal consonants (for hyponasality)
-
4 types of cleft palate speech deviations?
- Resonance-hypernasality
- airflow-nasal air emission
- air pressure-weak or absent oral pressures
- articulation-maladaptive compensatory misarticulations
-
Airlfow and Air pressure assessment- nasal air emission:
distinguish between potential sources of NAE:
constant/pervasive: most likely___?
due to fistuala: relates ___?
phoneme specific: ___?
- true VP closure problem
- to place of production; place of production will be at or anterior to the fistula
- learned; affects only selected phonemes
-
Sources of nasal air emission (NAE)?
fistula and/or VP port
-
Sources of nasal air emission (NAE):
Fistula can be located?
- anterior
- posterior
- nasolabial
-
Sources of nasal air emission (NAE):
VP port
is due to?
- true VP problem
- PSNE
- persisting post-op
