Study Guide Flashcards
What anatomical structures and features affect the acquisition and production of speech sounds?
moveable and immoveable articulators
What are the moveable articulators?
- jaw
- lips
- tongue
- velum
- uvula
What does the Jaw help facilitate?
resonance and articulation
What are the immoveable articulators?
- hard palate
- alveolar ridge
- teeth
What are lips important for the production of?
bilabials
What is the most vital articulator for the production of the majority of English sounds?
tongue
What is the progression of speech sound acquisition?
- reflexive to purposeful
- undifferentiated to differentiated
How does speech develop from undifferentiated to differentiated?
- open to CV word structures
- variegated CV combination
- Closed CVC word structures
- connected speech
Why are infants early productions restricted to phonemes produced primarily by the jaw?
because they rely on jaw movement due to limited control of lips and tongue
what does the production of full range of English sounds (consonants & vowels) require?
lower lip and tongue movements independent of the underlying jaw
What are the implications of structural deficits and poor oral motor control?
- constrained speech sound acquisition (infants and children)
- articulatory errors
- reduced intelligibility
- restricted verbal communication skills
What type of speech errors would you expect with malocclusions?
- the implications vary per case
- some can develop compensatory strategies
- articulation disorders
What type of speech errors would you expect with cleft lip and/or palate?
-surgery completed within first two years to close fissure without permanent effects on articulation
What type of speech errors would you expect with ankyloglossia?
-limits tongue tip mobility so it compromises speech sound production
What type of speech errors would you expect with a submucosa cleft?
?? can’t find this in my notes, but it’s on the study guide.. ?
What type of speech errors would you expect with velopharyngeal insufficiency?
- nasal emission: air escapes through nasal cavity & unable to build intraoral pressure for the production of oral sounds
- glottal stop: stopping & sudden release of air within glottis for /p,b,t,d/
- pharyngeal stop: pharyngeal contact using base on tongue for /k/ and /g/
- velar fricatives: distorted /k,g/ for sibilants /s, z,ʃ, ʒ/
- mid dorsum palatal stop: /j/ for /t,d,k,g/
What are the possible causes of poor oral motor and speech deficits?

What are the etiological factors for Apraxia of speech?
- acquired: stroke or brain injury to the motor cortex
- developmental: without evidence of neurological damage
What are the speech and neural characteristics of apraxia of speech?
- limited verbal output
- difficulty with volitional oral & speech movements
- automatic speech preserved
- inconsistent sound errors:omissions, deletions, substitutions, distortions
- self corrections
- groping and effortful speech productions
What is the purpose of an oral motor exam?
- it’s a critical component to speech assessments
- measure structural and functional integrity of speech mechanism
What do you assess in terms of FUNCTION during an oral motor exam?
- adequacy of system to produce non-speech and speech related movement

- face, nose, mouth
During an OME what do you observe in terms of structure of the lips?
- drooping
- drooling
- resting position
- scarring
During an OME what do you observe in terms of function of the lips?
- range of motion (ROM): smile vs. pucker
- pressurizing without losing air from nose
- DDk rate for /p^/
During an OME what do you observe in terms of structure of the tongue?
- size
- atrophy
- abnormal movements
- mobility: protrusion, elevation, lateralization, rotation*
During an OME what do you observe in terms of function of the tongue?
- strength
- mobility: ROM, Ankyloglossia, DDK rate for /t^t^t^/
During an OME what do you observe in terms of structure of the hard palate?
- height and width
- color
- check for clefts, fistulas, fissures, or appliances
During an OME what do you observe in terms of function of the hard palate?
immobile structure: nothing to test here
When checking the structure of the hard palate, what can the palate being too high mean?
-too high may signify structural issues
Why do we check the color of the hard palate?
-blue tint at midline may indicate a submucosa cleft
During an OME what do you observe in terms of structure of the soft palate?
- condition of the uvula
- symmetry and length
- repaired cleft
During an OME what do you observe in terms of function of the soft palate?
- movement of velum during production of /ɑ/ either sustained or repeated
- listen for hypernasal or hyponasal speech during production of stop consonants
During an OME what do you observe in terms of structure of the teeth?
- overall condition
- missing/extra teeth
- occlusion pattern
In terms of feeding skills, what should a 6-9 month old be doing?
assist with feeding
In terms of feeding skills, what should a 9-12 month old be doing?
finger feeds
In terms of feeding skills, what should a 12-15 month old be doing?
holds cup and starts using spoon
In terms of feeding skills, what should a 15-18 month old be doing?
uses straw and uses spoon independently

YES!
What are the natural consequences of connected speech processes?
- adaptive changes to phonetic and phonological forms
- complex articulatory demands
What are connected speech processes governed by?
- increased rate of speech
- acoustic perception, learned cognitive or phonological rules
What is co-articulation?
- overlapping movements or dynamic coordination of articulators within vocal tract
- depends on the phonetic context
- the results are two articulators “co-produce” or share features
What is assimilation?
- adaptive articulatory changes
- changes in manner, place, and voicing properties
What is progressive/perseverative assimilation? GIVE AN EXAMPLE!
- phoneme 1 → phoneme 2
- sound segment influences a FOLLOWING sound
-EX: /dʒʌmpɪn/ vs. /dʒʌmbɪn/

“would you?”
“in case you need it”
“has your letter come?”
What is Elision Assimilation? GIVE AN EXAMPLE!
-omission of one or more sounds in a word or phrase

- regressive
How do we Segment Speech?
-spontaneous speech must be “broken down” into smaller components
