Final- Older Info Flashcards
(52 cards)
Articulation
motor movement of speech
Phoneme
Smallest unit of sound
Articulation disorder
Motor-based disorder. Secondary to child’s inability to motorically produce sounds.
Phonological disorder
collapse in Phonemic contrast
Rule-based disorders.
Lack of knowledge of where to appropriately use sounds that they can produce. Neutralization/collapse in phonetic contrast.
Morphemes
smallest unit of meaning and made up of a combination of phonemes
- Free- can stand alone
- Bound- prefixes and suffixes that are added to words to change meaning
Phoneme classification
Onset- Phoneme or cluster that initiates a syllable
Nucleus- the vowel at the syllable level
Coda- Phoneme or cluster that closes a syllable. Follow the nucleus
Rhyme- Nucleus and the coda
Subsystems of speech
- Respiration- lungs. Air that’s pushed up through VFs. Driving force
- Phonation- Voice production that occurs when VFs are adducted. Can have hyperadduction or hypoadduction
- Articulation-How resonating sound is shaped. Teeth tongue, palate, etc.
- Resonance- Modification of voice as it travels through the pharynx and oral/nasal cavities. Based on modifications in the size and shape of resonating cavities. Cleft palate.
Also needed for speech:
Adequate hearing sensitivity- for both input and monitoring output
Need intact neurological system for control and integration of all subsystems.
Round
Tense
Producing sounds with lips rounded or protruded (r, w)
Sounds made with a relatively greater degree of muscle tension or contraction at the root of the tongue (mostly voiceless-p, t, k, ch, j, f, th, s, sh, l)
Continuant
Nasal
Strident
Sonorant
Sounds made with an incomplete constriction. Glides, fricatives and liquids.
Sounds that resonated in the nasal cavity.
Sounds that force the air stream through a small constriction. Fricatives and Affricates.
Produced by passing of the air stream relatively unimpeded. Nasals and glides
Interrupted
Lateral
Voice
Obstruent s
Sibilants
Approximants
Rhotic
Syllabics
- Interrupted- complete closure/blockage of air (stops and affricates)
- Lateral- /l/ tongue is placed on alveolar ridge and the air flows laterally.
- Voice- VFs are vibrating
- Obstruents- Stops, fricatives and affricates. Consonants produced by complete closure or narrow constriction.
- Sibilants- Produced with high frequency. Have a more strident quality and a longer duration. (s, z, sh, zh, ch, j)
- Approximants- Sound is produced with approximating nature. Doesn’t completely make contact between two articulators (glides and liquids)
- Rhotic- /r/ Sound with r coloring.
- Syllabics-Any sound that can stand as the nucleus of a syllable (all vowels and l, n, m, r)
Suprasegmentals of speech:
o Rate o Rhythm o Stress o Juncture o Pitch-cycles per second o Loudness o Intonation o Prosody
3 primary levels of valving
o Vocal folds
o Velopharyngeal mechanism
o Articulators of oral cavity
Prelinguistic stages of infant vocalization
Phonation stage- reflexive and nonreflexive. R= Crying, burping, hiccupping (natural sounds) N=laughing, raspberries, giggling. (Birth- 1 month)
o Cooing and Gooing Stage- primarily producing back sounds an quasi resonant vowels (2-3 months)
o Expansion/exploration- vocal play – start testing what they can do (4-6 months)
o Canonical/reduplicated Babbling- duh duh duh (7-9 months)
o Variegated babbling- more adult-like intonation without true words play with CV words (10-12 months)
- Protowords (hold meaning and used consistently with a gesture) Meaningful but don’t have a recognizable adult model. Babi for pacifier.
- Jargon
Regressive idioms
hold on to simplified version even after they are able to say it correctly – TAY TAY for Katie.
(frozen forms): Despite what they can produce Childs static or unchanging pronunciation of words despite his or her more advanced phonological skills. Nick names (boo boo)
Sound acquisition
o By age 3-0: Consistent production of H, W, M, N, B ,P, F
o By age 4-0: Consistently produce p k, g, y, nj, d, t
o By age 6-0: L. CH, J, SH, V. may still have errors with r, th (voiced/voiceless), s, z, zh
o By age 8-0 to 9-0: Should have everything.
Phonological processes
describes a persons speech errors. Simplifications that the person produces to a whole class of sounds. Occurs in normal children and children with a disorder.
Syllable structure processes
sound changes that modify the syllabic structure of words as the child attempts the adult target.
WSD
Reduplication
o Unstressed Syllable Deletion- AKA weak syllable deletion. Where child omits one or more syllable in a multisyllabic word.
o Reduplication- aka Doubling. Totally or partially repeats a syllable of the word in a multisyllabic word. Baba=Bottle Bada=bottle (partial)
Diminutization
Epenthesis
FCD
ICD
o Diminutization- Where they add an ‘e’ at the end of a word. Ex. “Cuppy”
o Epenthesis- Where they insert the schwa between two phonemes of a cluster. Supoon for spoon
o Final Consonant Deletion- Deletes the final consonant or cluster at the end of the word.
o Initial Consonant Deletion- Deletes initial consonant or cluster of a word. Op for cop. Very rare for normal developing children.
Cluster reduction
Reducing one or more sounds or phonemes of a cluster. Partial or total. Top for stop. Op for stop. Can be confused with other processes. Can have multiple things at once. Cluster simplification-substitution of one or all phonemes of a cluster. Deet for street. Bwue for blue.
More processes:
o Stopping o Deaffrication o Velar fronting o Depalatalization o Backing o Liquid gliding o Vocalization o Labial assimilation o Velar assimilation o Nasal assimilation o Alveolar assimilation o Prevocalic voicing o Postvocalic devoicing
o Processes disappearing by age 3-
final consonant deletion, weak syllable deletion, velar fronting, reduplication, prevocalic voicing, and consonant assimilation.
o *Processes persisting after age 3-
cluster reduction, epenthesis, gliding, vowelization, stopping, depalatalization, final devoicing - notes
