Chapter 8: Transcription of Speech Sound Disorders Flashcards
Speech Sound Disorders
Umbrella term for disorders involving speech sound production
Articulation Disorder
Problem in producing a limited number of phonemes or errors tied to motoric aspects of speech production
Phonological Disorder
Difficulty with sound system of a language and utilizing rules that govern combination and order of phonemes
Allophonic Variations
-not speech sound disorder
-using a tap, glottal stop, or unaspirated stop in certain contexts is perfectly normal
What is the age at which children typically develop and master speech sounds?
-The answer may vary depending on socioeconomic status, number of children examined, and how speech sample is obtained
-The answer may also vary depending on definition of mastery
Mastery
Age at which a phoneme is produced with certain degree of accuracy
Customary Production
Age at which a phoneme is produced with greater than 50% accuracy
Phonological Process
-simplifications of adult speech
-as children mature, suppression of processes
-occur as the result of a substitution, omission, or assimilation
General Findings on Typical Phonological Development
90% mastery of several phonemes occurs by age 3 years. Mastery of all phonemes may not be complete until age 7–9
`
General Findings on Typical Phonological Development: Manner of Articulation
Nasals and stops are acquired earlier than glides, fricatives, liquids, and affricates
General Findings on Typical Phonological Development: Place of Articulation
Sounds produced in the front of mouth (labial, alveolar) are acquired earlier than velar and palatal sounds
Phonological Processes Include
-Syllable structure processes
-Substitution processes
-Assimilatory processes
Weak syllable deletion
-Deletion of an unstressed syllable
-telephone: /tɛfon/
Final consonant deletion
Reduction of a syllable to a consonant-vowel pattern
-bake: /beɪ/
Reduplication
-repetition of a syllable
-daddy: /dædæ/ or /dɑdɑ/
Cluster Reduction
-Deletion of a consonant from a consonant cluster
-stripe: /tɹaɪp/, /taɪp/, or /ɹaɪp/
Substitution Processes
-Stopping
-Fronting
-Deaffrication
-Gliding
-Vocalization
Syllable Structure processes
-weak syllable deletion
-final consonant deletion
-reduplication
-cluster reduction
Stopping
-Substituting a stop for a fricative/affricate
-sake: /teɪk/
Fronting
-Substituting an alveolar for a velar/palatal sound
-Cat: /tæt/
Deaffrication
-Substituting a fricative for an affricate
-chip: /ʃɪp/
Gliding
-Substituting a glide for a liquid
-red: /wɛd/
Vocalization
-substituting a vowel for a postvocalic liquid
-help: /hɛʊp/
Assimilatory Processes
-labial assimilation
-alveolar assimilation
-velar assimilation
-voicing assimilation
