4. I. DEVELOPMENT IN INFANTS A. Introduction
In our profession, there is more emphasis on the birth-3 yrs. Population
More preemies with feeding problems—these are the artic/phono/oral motor kids we see later
When we gather case histories, ALWAYS ask about feeding/sucking/swallowing problems
5. II. INFANT SPEECH PRODUCTION Stage 1—Phonation Stage—Birth-1 mo.
6. Owens, Metz, & Farinella 2011:
7. Owens, Metz, & Farinella, 2011: (continued)
9. Stage 2—Cooing and Gooing—2-3 mos.
Stage 3—Exploration and Expansion-4-6 mos.
10.
Stage 4—Canonical/Reduplicated Babbling—7-9 mos.
Stage 5—Variegated Babbling—10-12 mos.
11. III. TRANSITION PERIOD Prelinguistic?linguistic phonological development
Protowords/vocables:
12. IV. FIRST REAL WORDS: MEANINGFUL SPEECH True word:
1. Stable—consistently used
2. Used in a particular context
3. Must resemble the adult form
Advanced forms/progressive idioms
Frozen forms/regressive idioms
13. V. SOUND SYSTEM DEVELOPMENT A. Single Phonemes
1. Cross-sectional studies
Age of development: 50% of children produce sound accurately
Age of mastery: 75-90% of children produce sound accurately
By 3:0 years:
By 4:0 years:
By 6:0 years
By 8:0 years:
2. Longitudinal studies
14. B. Consonant Clusters Very little information
Earliest:
Latest:
15. C. Vowels Very little information on development
Most vowels developed early (1-2 years of age)
Exceptions: /r/ vowels—between 4-6 yrs. or even later
Hearing impaired children have difficulty
16. VI. COMMON ERRORS A. Liquids
w/l w/r
Deletion in word-final position
B. Nasals
m/n n/ng (word-final position)
17. C. Alveolar and Palatal Fricatives and Affricates Stopping of /s/-initial toap/soap tee/see
Stopping of other fricatives and affricates, esp. in word-initial position dow/show
Dental distortions of /s/ thing/sing
Deaffrication of /ch/ shoe/chew
Deletion of word-final fricatives /s, z, sh/
18. D. Glides Deletion of /j/, /w/
Substitutions: w/j, d/j, h/j, l/j
Examples: lello/yellow hes/yes
Wung/young
19. E. Labial and Dental Fricatives F/th fumb/thumb
S/th sing/thing sick/thick
B/v balentine/valentine dub/dove
D/th dis/this broder/brother
20. F. Stops Deletions of word-final stops, especially labial and alveolar stops
Fronting of velars (especially in word-initial position)
Tat/cat done/gun
21. G. Consonant Clusters Obstruents: stops, fricatives, affricates (everything except glides, liquids, and nasals)
***usually clusters are reduced to the obstruent***
Obstruent + /w/ clusters reduced to the obstruent
Obstruent + /l/ clusters reduced to the obstruent
22. Obstruent + /r/ clusters reduced to obstr.
Clusters with /s/ + consonant reduced to /w/, nasal, or stop component of the cluster
Three-member clusters (e.g., squirrel) usually reduced to the stop

27. Aspects of phonological awareness: Sound blending
Rhyming
Alliteration
28. Phoneme isolation
Sound segmentation
Syllable identification
