how does a delay apply to speech sound disorders?
speech production patterns that typically occur in younger children (2-9 years)
typical speech errors of their age
most develop typical speech development by age 6 with treatment
how does a disorder apply to speech sound disorders?
child’s speech is not what is seen in typically developing children at any age
atypical phonological pattern
how does a difference apply to speech sound disorders?
differences in speech attributed to cultural/linguistic/regional backgrounds
accent/dialect
gender affirming voice
what is the difference between a phonetic and phonemic inventory?
phonetic: assesses articulation- if you can say the sound
phonemic: assess meaning and convey meaning- if you can use the sound correctly
what is an articulation disorder?
impaired motor production of speech
mostly distortions, less often impacts speech intelligibility, relative to child’s age, how the person uses the sound
functional: related to development or learning
what is a phonological disorder?
phonemic errors at phonological level that impacts language
know how to use phonemes but don’t know when or where to use them
omissions and substitutions, more often impacts speech intelligibility, error patterns that are not age appropriate, consistency in errors
what is a speech sound disorder?
umbrella term that is for errors in producing speech sounds
applies to both phonological and articulation issues
define intelligibility
subjective/perceptual estimate of how much a person is understood
reported as percentage of words understood in speech sample
useful to document needs for therapy and progress in therapy
the first concern of parents for speech therapy usually is…
poor intelligibility
what influences intelligibility?
context, rate, fluency, language difficulties, prosody, volume, proximity, familiarity, phonological patterns, dialect, listener’s hearing ability, background noise
a person with a phonological disorder is usually ____ intelligible than a person with an articulation disorder.
less

reported as percentage of words understood in speech sample
count words understood and divide by total number of words
what is severity?
qualitative judgment made by clinician that focuses most on speech production and takes into account how the client is impacted in terms of quality of life
not always related to intelligibility
how is severity associated with age and sound errors?
child may be compared to other kids their age and sex to determine a severity rating
7 year old with 4 SSD errors vs 4 year old with 4 SSD errors

client perspective
quality of life
number of sound errors
number of error patterns
accuracy of productions
what percentage is an error consistent?

how is severity related to articulation and phonological disorders?
both include a severity rating
