Speech Sound Disorders Terminology Flashcards
minimal contrast
2 words or phonemes that are 1 feature different
maximal contrast
2 words or phonemes that are more than 1 feature different
phonetics
how phonemes are produced by articulators
phonemic
the way phonemes carry meaning
phonetic inventory
a list of all the sounds the client is able to produce even if used in the wrong context
phonemic inventory
a list of all the sounds a client can produce when they’re used to convey meaning
articulation
The totality of motor processes involved in the planning and execution of speech.
Surface level speech representation.
Can be described using accuracy and placement of articulators, tension and force, duration and speed, and air pressure
phonology
Patterns of phonemes that occur in a language.
Underlying language representation.
Describes inventory and arrangement of sound units.
articulation disorder
Impaired motor production of speech sounds resulting in distortions.
A movement error at the phonetic level with speech impacts.
Less often impacts intelligibility because there is still sound contrast.
phonological disorder
Impaired comprehension and or use of the sound system of a language resulting in omissions or substitutions.
Described as non-age-appropriate error patterns.
More often impacts intelligibility.
omission/deletion
Speech sound omitted.
Common in phonological disorders.
substitution
Standard speech sound substituted for another standard speech sound.
Common in phonological disorders.
distortion
Nonstandard speech sound substituted for a standard speech sound.
Common in articulation disorders.
phonological awareness
Awareness of the phonolgical units in a language.
How words are made of sounds and how sounds make up words.
Can children identify and manipulate sounds of their language.
Very important for reading and literacy.
coarticulation
Movement involved in producing one sound influences the sounds around it to produce the allophonic variation of the phoneme.
Because of the speed articulators move with.
assimilation
Target sound becomes more like the sounds around it.
Not allophonic variation.
speech delay
Typical speech production errors for younger children that occur in older children.
2-10 yrs.
Intervention can lead to typical speech development by 6 yrs.
speech disorder
Atypical speech production error pattern not seen in any typical development.
speech difference
Speech sound production differences attributed to linguistic or cultural factors such as accents or dialects.
intelligibility
Subjective judgement made by a listener about how much can be understood.
Can be quantified as number of words understood and written as %.
Artic disorders more intelligible than phon disorders.
GIFTA
Common test to measure intelligibility in connected speech.
severity
Qualitative judgement of the number of sound errors and error patterns compared to normative data to determine impact.
Ranges from mild to severe.
Age dependent.
consistent pattern
A specific error occurs more than 40% of the time.
mild severity
Not very many speech errors.
Less concern, might not refer child.
