Speech Sound Development and Disorders Flashcards
What is the difference between an articulation approach and a phonological approach to treating SSD?
Articulation approach: looks at how a child learns individual phonemes and focuses on speech-motor control
Phonological approach: looks at how a child learns sound patterns and focuses on the rules of a sound system in a given language
What does naturalness refer to?
How often a sound occurs in a given language; the more often a sound occurs, the more natural it is
What is the difference between unmarked sounds and marked sounds?
unmarked sounds are natural sounds, that are learned earlier. Marked sounds are unnatural sounds that are learned later.
What are allophones?
variations of a phoneme
What is the difference between phonemic representation and phonetic representation?
phonemic: socially accepted representation of speech sounds and words
phonetic: speaker’s production of speech sounds and words
What paradigms or models are used to distinguish phonemes?
distinctive feature paradigm and place-voice-manner paradigm
What is the distinctive feature paradigm?
paradigm used to classify vowels and consonants as having particular distinctive features
What is the place, voice, and manner paradigm?
paradigm used to classify vowels and consonants based on their place (where the constriction of the vocal tract happens), voice (whether the vocal folds are opened or not), and manner (the degree and type of constriction of the vocal tract).
How is a stop consonant produced?
by completely stopping the flow of air
How is a fricative produced compared to an affricate?
Fricatives are produced by narrowing certain parts of the oral cavity, but an affricate is produced by narrowing certain parts of the oral cavity while completely stopping the flow of air.
How is a glide produced compared to a liquid?
Glides are produced by changing the shape of articulators, whereas liquids are produced with the least restriction of the oral cavity
Regarding speech sound development, what is the difference between natural phonology theory and generative phonology theory?
Natural phonology theory: it is normal for children to use phonological processes because it helps to simplify the adult target word
Generative phonology theory: phonology is generated from phonological rules
Regarding speech sound development, what is the difference between linear phonology theory and nonlinear phonology theory?
Linear phonology theory: speech sounds are acquired sequentially
Nonlinear phonology theory: speech sounds are not totally acquired sequentially and are influenced by other factors
When assessing a child’s speech sound development, an SLP should conduct the following:
Case history —-> screening —> oral mechanism exam —> hearing screening —> language sampling —-> evaluate child’s speech at the single word level and conversational level -> identify any phonological processes—> compare their performance to developmental norms—> see if they are stimulable for misartculated sounds —> identify treatment targets
Related assessment procedures for assessing a child’s speech sound development are the following:
co-occuring language difficulties; assesing hearing, behavior, and intellectual ability; the presence of physical and neurological disabilities; possible influence of another language or dialect
When targeted a phoneme for therapy, an SLP is encouraged to target the
earliest developing sound
What are the stages of infant development for speech sound production?
Stage 1 (Phonation stage): vocalizations; Stage 2 (2-4 months): cooing; Stage 3 (4-6 months or the expansion stage): vowel like sounds, CV combinations, and growls; Stage 4 (6-8 months): reduplicated babbling (e.g., ba, ba, ba); Stage 5 (8 - 12 months): variegated babbling (E.g., ba, da, ka, ma); Stage 6 (1 year old): first word
Which sounds do children develop first?
vowels
Which type of consonants do children develop from first to last?
Nasals—>stops and glides—> liquids->fricatives—>affricates—>consonant clusters
At 2 years old, a child is likely ______ intelligible.
60-70%
At 3 years old, a child is likely ______ intelligible.
75-80%
At 4 years old, a child is likely ______ intelligible.
90-100%
What is a phonological process?
patterns of sound errors that typically developing children use to simplify their speech when they are learning to talk
What is vocalization?
A phonological process in which a vowel is substituted for a consonant (e.g., noodoo for noodle)
