SSD Flashcards
dentalization
tongue approaches upper incisors
often occurs d/t coarticulation
d̪
palatalization
occurs when a sound is produced as a palatal, rather than a nonpalatal
j
velarization
occurs when tongue placement moves in the direction of the velum for palatal sounds
ɣ
lateralization
occurs when air is released laterally on any consonant production other than l
devoicing
not voicing a voiced consonant
total devoicing is marked by its voiceless counterpart
nd
voicing
voicing an unvoiced consonant
total voicing is marked by its voiced counterpart
⌄
aspiration
pʰ
unaspirated
p⁼
unreleased stop plosive
result when closure is maintained, not released
d̚
consonantal
[+/- cons]
distinguish true consonants from vowels & glides
block, redirect, or narrow airflow
consonantal
sonorants [+/-son]
distinguish sounds that allow unimpeded airflow from sounds that block or constrict the airflow
obstruent
[-son]
stops, fricatives, affricates
approximant
[+/-approx]
distinguish sounds that have a constriction in the vocal tract while allowing the frictionless escape of air (eg vowels & non nasal sonorants
major class features
consonantal
sonorant
approximant
nasals, liquids, glides
sonorant
stops, fricatives, affricates
obstruent
vowels and non-nasal sonorants
approximant
true consonants
consonant
phoneme
speech sound that serves to contrast meaning between words in a language (mat vs bat)
allophone
phonetic realizations of a phoneme; sounds that do not change linguistic meaning of morphemes
T/F: fricatives imply stops
TRUE
naturalness
easier to articulate, more common within and/or across languages
markedness
phonetically more complex, less common across languages
phonological impairment
cognitive linguistic difficulty with learning the phonological system of a language
characterized by pattern based errors
most common type of SSD
phonological impairment
inconsistent speech disorder
characterized by inconsistent productions of the same word
problem with phonological assembly without accompanying oral motor difficulties
articulation impairment
characterized by sound errors typically involving sibilants (s, z) and/or rhotics (r)
speech perception difficulties may underlie an articulation impairment
childhood apraxia of speech
motor speech disorder associated with planning and programming movement sequences, resulting in dysprosody and error in speech sound production
childhood dysarthria
motor speech disorder involving difficulty with the sensorimotor control processes involved in speech production, typically programming and execution
neurological condition or TBI
problem with mental representation
phonological impairment
motor execution issues (place, manner, and voicing issues)
articulation impairment
impact of SSD
negative social relationship and academic achievement
low self-esteem
average age of referral of SSD
4;3
ratio of SSD of boys to girls
2:1
more children with SSD have a:
family history
what is phonological impairment?
cognitive-linguistic difficulty, pattern-based speech errors
what is articulation disorder?
specific speech sounds due to motor speech difficulty
intelligibility by age
100% by 4 years to family and 5 years to strangers
most manner classes present, 90% of consonants produced correctly by this age:
5 years
phonological processes that disappear by age 3:
reduplication
place and manner assimilation
weak syllable deletion
prevocalic voicing
FCD
velar fronting
reduplication disappears/persists by age 3

purpose of assessment
describe child’s abilities and difficulties
diagnosing the presence of SSD, intervention planning
measuring the outcome of intervention
consistent test materials, administration procedure, and scoring rules
standardized test
“serve as gateways to services” can be norm-referenced or criterion-referenced
standardized test
predictive validity
standardized test
typically do not have a standardized processes for administration, analysing, scoring
non standardized (informal) test
not accompanied with normative data
non standardized (informal) test
developed by SLP and researchers for an intended purpose and population
non standardized (informal) test
norm referenced test
comparing a child’s performance against normative samples, the presence of SSD, eligibility for service
criterion referenced tests
used to measure skills in terms of absolute levels of mastery
does not tell whether a child differs from the norm, but is useful for baseline and progress measures
criterion referenced tests
can be either standardized or informal
criterion referenced tests
correct fails; more important
sensitivity
correct passes
specificity
identify disordered as disordered
sensitivity
identify normal as normal
specificity
static assessment
assess a child’s performance at a particular time
dynamic assessment
consider children’s performance and capacity to learn with cues and feedback
ZPD
speech sample analysis
type of informal assessment used to identify speech pattern errors
useful for goal setting and planning Tx approaches
SODA
traditional
useful for articulation disorders
substitution, omission, distortion, addition
independent analysis
analyze speech independent of the adult phonological system
