7.LA Speech Form 3+
Language Acquisition SLP329
Term | Definition |
---|---|
Error-based analysis at age three. Why? | Phonemic inventories track phonemes present, but by age 3, children's speech is nearly adult-like. Correct phonemes outnumber incorrect. It becomes easier to measure errors than successes. |
3 types of phonetic errors | Substitution, Omission, Distortion |
Distortion errors | Dentalization, lateralization, derhotacization. These are not universally typical. |
Study of arctic development | Cross-sectional "acquisition-age" studies. Phonological process studies. |
Acquisition-age studies | "Mastery age" for individual consonants. Criticism: 1. children do not acquire phonemes individually. 2.uninformative about error type. |
Vowel acquisition (3) | 1.More than 85% correct production from age 2 (except for the rhotic vowels). 2.Vowels are less likely than consonants to be misarticulated 3. Numerous non-rhotic vowel errors is abnormal over age 2 |
“Natural” sounds and syllables | 1.Manner: most to least natural- Stops, fricatives, affricates (most common earliest manner classes: stops, glides, nasals) 2. Place: Anterior to posterior consonants 3.Most natural syllable shape: CV/CVCV then CVC then CVCC |
Structural processes (4) | Reduplication, weak syllable deletion, final consonant deletion, cluster reduction |
Substitution processes (2) | stopping, fronting, |

Substitution processes (3) | stopping, fronting (velar & palatal), gliding |
Assimilation processes (2) | progressive, regressive |
Phonetic mastery | Complete by age 8 with exception of isolated frozen errors (pasghetti) |
Phonological representation | Age 5-8 development shifts to sound symbol correspondence, metaphonological tasks (rhyming, alliteration, pig-latin, blending/segmenting) |
