Exam 2 Flashcards
Assessment
to distinguish normal from disordered speech for diagnostic purposes
treatment
to appropriately select target phonemes for therapy
appropriate use of norms in clinical decision making
individual differences may exist
norms based on 75-90% master of a normed group
age of mastery may vary across studies
some approaches address LATER developing sounds before targeting EARLIER developing sounds
norms should just be used as one “piece of the puzzle”
newborns prefer their ____________ voice over other voices
mother’s
newborns prefer their ____________ languages over foreign languages
ambient
sensitivity to ambient language _________
prosodic patterns
language-universal
infants discriminate phonetic contrasts of all languages
prelinguistic stage-speech perception
BIRTH: language- universal
language-specific perception for vowels
detection of typical stress patterns in words
decline in foreign-language consonant perception
12 MONTHS: increase in native-language consonant perception
speech perception within the first year of life
infants appear to learn how to selectively perceive only the contrasts in their language and lose the ability to perceive other contrasts
by the time they are only a year old. infants perceive only the categories that are
contrastive in the language they’ve grown up with
babbling is
NOT random
consonant-like sounds that are babbled are restricted to a
small set of segments
transition from babbling to 1st words is
CONTINUOUS
Stark’s Classification for Prelinguistic Development
five levels
stages are not distinct; they overlap
ages for each level should be considered approximate
birth - 2 months
STAGE 1
Reflexive crying and vegetative sounds
STAGE 1
reflexive vocalization: cries, coughs, grunts, and burps
STAGE 1
vegetative sounds: grunts, tongue clicks, and other noise associated with feeding
STAGE 1
speech-like sounds are rare
STAGE 1
cooing and laughter or controlled phonation
STAGE 2
1-4 months
STAGE 2
vowel-like sounds with some consonantal elements (back of the mouth)
STAGE 2
Quasi-resonant nuclei: syllabic nasal consonant or nasalized vowel sound like
STAGE 2
most primitive vegetative sounds start to disappear
STAGE 2
at 4 months: laughter emerges
STAGE 2
Vocal play
STAGE 3
3-8 months
STAGE 3
longer segments of prolonged vowel or consonant-like steady states
STAGE 3
pitch and loudness variation
STAGE 3
raspberries
STAGE 3
variations in tongue position, a greater variety of vowels will be noted during vocal play
STAGE 3
basic canonical babbling
STAGE 4
5-10 months
STAGE 4
reduplicated babbling
similar strings of consonant vowel productions (baba, tata, dada)
variegated babbling
variation of consonants and vowels from syllable to syllable (madaga, tikitoo)
reduplicated and variegated babbling
STAGE 4
a self-stimulatory manner ->
ritual imitation games with adults
STAGE 4
imitation of speech behaviors
STAGE 4
Jargon (advanced forms)
STAGE 5
9-18 months
STAGE 5
what is jargon?
strings of babbled utterances that are modulated primarily by intonation, rhythm and pausing
sounds like real sentences without actual words
STAGE 5
eye contact, gestures, and intonation patterns that are similar to the actual language intonation
STAGE 5
more complex syllable structures: CCV, CCVC
STAGE 5
5 prelinguistic stages
vegetative sounds
cooing
vocal play
canonical babbling
jargon
in prelinguistic stage, speech sounds do not
carry linguistic function
speech sounds are considered to be
nonphonemic in nature
vocoids
nonphonemic vowel-like productions
contoids
nonphonemic consonant-like productions
syllable structures
open syllable shapes are most frequently observed: V, CV, VCV, CVCV
Quantity
amount of prelinguistic vo alization is positively related to later language development
diversity
greater language growth seen in children with more contoid babble compared to more vocoid babble
greater language growth is related to
babble complexity
greater language growth related to increased diversity of
“consonant” productions (contoid)
prosodic features
stress, intonation, pausing, and duration leading to rhythmical effects
during canonical babbling stage (~6 months)
developing intonation patterns
falling pitch is the most common intonation contours in the first year of life
the string of babbles sound like native English intonation patterns
jargon stage
link between babbling and adult-like speech
proto-words
Proto-words
do not match adult word production
produced consistently under specific conditions
AKA: vocables, phonetically consistent forms, invented words, quasi-words
Babbling vs. Protowords
babbling:
does not resemble adult production
inconsistent
mostly no word meaning
car: baba, data, bobi
protowords:
does not resemble adult production
consistent
car: bubu
recognizable sounds and syllable structure
the first words
the first words
produced the same each time
ball - ba
help - hep
more - mo
related to the actual word from that language
protoword vs true word
protoword:
does not resemble adult production
“lala” for car
true word:
phonetically similar to adult production
“ka” for car
first 50-word stage: age range
12 months to 18-24 months
first 50-word stage: production
protowords
1 word utterances
first 50-word stage: comprehension
200 words
first 50-word stage: phonetic variability
unstable productions of words
first 50-word stage: limitation of syllable structures
CV, VC, CVC, CVCV
single or reduplicated syllables
first 50-word stage: limitation of phonemes
consonants: / p B M t D N k g h sh w/
vowels: / a u i/
a larger inventory of sounds was found in the word ____________ position than the word _________ position
initial
final
________________ inventories contained voiced stops prior to voiceless ones (prevocalic voicing)
word initial
__________ inventories contained voiceless stops prior to voiced ones
word final/syllable final
most common consonant inventories by 50 words productions from two children in US
coronal & labial
prosodic feature development
falling pitch still predominant
more prosodic variation to indicate difference in meaning and communicative intent
naming, labeling
10-12 months; falling contour
requesting, attention getting, curiosity, surprise, recognition, insistence, greeting
13-15 months; rising contour, from high pitch and drops to lower one; e.g., all gone
playful anticipation, emphatic stress
<18 months; high rising
warnings, playfulness
~18 months; falling-rising, rising-falling
language development from 18-30 months: production
150-300 words
2 word utterances
language development from 18-30 months: comprehension
1200 words
language development from 18-30 months: 2 word utterances
semantic relationship
syntactical development
language development by 5 years old: production
2200 words
questions, negation, clauses, compound sentences
effective use of language
language development by 5 years old: comprehension
9600 words
90% criterion
90% of the participants produced the consonant correctly
stops, nasals, glides are earlier developed compared to
fricatives, affricates, liquids
T/F: using the 90% criteria, the age range of the acquisition of /g/ is 3;00-3;11. That indicates a child can produce /g/ with 90% accuracy at this age range.
FALSE
atypical phonological processes
syllable structure: Initial Consonant Deletion
substitution: affrication, palatalization, backing
Velar harmony
guck for duck; Assimilation
labial harmony
/bebu/ for table; Assimilation
voicing assimilation persist up to
5-6 years
if velar/labial harmony persist beyond age 3, it can be a sign for
a disordered phonological system
