Speech Sound Disorders Flashcards
(42 cards)
allophone
a nondistinctive phonetic variant for a phoneme (ex/ the /k/ is produced differently in ski, key, and caw, but is still /k/)
coarticulation
the influence of phonetic context on speech production
cognate
one of a pair of sounds that are different by just one phonetic feature (voicing in english) - ex/ s & z
flap
a modified stop, in which a rapid flapping motion of the tongue tip contacts the alveolar ridge (used for the /t/ and /d/ in words like city and ladder)
homorganic
sounds that have the same place of articulation (m and b)
eggressive sounds
formed from outflow airstream
ingressive sounds
formed from inflow airstream
obstruent
stops, fricative, and affricates b/c they have a complete, or narrow, constriction of the vocal tract
rhotacization
a sound that has /r/ coloring
sibilant
speech sound w/ intense, high-pitched noise (ex/ s and sh)
strident
a speech sound w/ intense frication noise like sibilants but also /f/ and /v/
Model - Behavioral Theory
the consequences of the infants’ vocalizations (i.e., reinforcement) is what’s necessary for them to learn language
criticism of behavioral theory
lack of data to support role of caretakers’ use of selective reinforcement of speech sounds for development
Model - Distinctive Features Theory
phonological development is realized as the development of feature contrasts, beginning w/ maximal contrasts (e.g., consonants vs. vowels, nasal consonants vs. oral consonants) and working up a hierarchy
- babbling not related to meaningful speech
Model - Generative Phonology
proposes 2 levels of language - surface level (what is spoken) and deep level (abstract representation of language) - underlying representations is used to talk about what children know about language and what they don’t know on a scale of 1-6, and how that affects their productions
- complex marking system
- clinically: describe errors in terms of phon rules often
Model - Natural Phonology
children are born with a set of “natural phonological processes” that reflect their developing speech motor systems - processes simplify production of speech sounds
- 3 broad categories of processes: syllable structure processes, substitution processes, assimilatory processes
- processes are reduced as kids develop
Model - Prosodic Theory
emphasizes the perception of whole words - early word productions are highly variable across children d/t differences of input
- development occurs as perception increases
Model - Interactionist-Discovery (Cognitive) Theory
- children create and apply their own strategies in an attempt to discover the rules and patterns of language - rules aren’t innate
- individual learning strategies account for differences
Model - Examples of Nonlinear Theories
- metrical phonology
- feature geometry
- optimality theory
- gestural phonology

list the 5 stages of babbling w/ ages
- Phonation stage (birth-1 month) - vegetative sounds like coughing, burping, grunting
- coo and goo stage (2-3 mo) - vowel-like, similar to back consonants & vowels
- exploration/expansion (4-6 mo)-vocal play, vowels, pitch/loudness variety, CV and VC sequences
- canonical babbling (7-9 mo) - reduplicated strings of CV, nonreduplicated CV, stops/nasals/glides/vowels
- jargon (10+) - variegated babbling, adult like intonations
most frequently occurring sound classess in first words
stops, nasals, glides
first vowels typically
/a/, /i/, /u/
early, mid, and late 8
early: m, b, j, n, w, d, p, h
mid: t, ng, k, g, f, v, ch, dj
late: sh, zsh, th-, th+, s, z, l, r
phonological patterns expected to be suppressed by age 3
- FCD
- (velar) fronting
- reduplication
- weak syllable deletion
- doubling
- diminuization
- consonant assimilation
- prevocalic voicing
