Syllable structure process

changes in the CV makeup

Most common syllable structure processes

1. weak syllable deletion

2. cluster reduction

3. Final consonant deletion

4. glottal replacement

Syllable Deletion/weak syllable deletion

deletion of syllable

- normal, especially during first 50 words

should be suppressed by around age 4

Final consonant deletion

final singleton (not preceded/followed by a consonant) consonant is omitted

should be suppressed by around age 3

Initial consonant deletion

initial singleton consonant is omitted

- atypical

Cluster reduction

cluster is 2+ abutting consonants

- one or more consonants comprising a consonant cluster is omitted

- cluster omission - all consonants omitted

will exist until about school age

Coalescence

replacement of two consonants with a different consonant that contains phonetic features of the two target consonants of a cluster

Epenthesis

addition of sound to word

/blu/ -- /bəlu/

suppressed around age 8:0

Diminutization

adding /i/ or /I/ to end of word "baby talk"

Doubling

repeating a monosyllabic word resulting in a multisyllabic word

Glottal Replacement

substituting a glottal stop for a consonant

-atypical --> cleft

Metathesis

transposing/reversing consonants in a word

- atypical --> apraxia

migration

movement of phoneme from one position to another

- atypical --> apraxia

Assimilation/Harmony deviations

articulatory properties of one sound influence the production of another

- frequent in very young children

- if beyond age 3:0 = sign for disordered phonological system

Progressive assimilation

sound in word is influenced by a preceding sound

----------->

regressive assimilation

sound is influenced by a later sound so that an earlier sound is changed

<------------------

normal

Labial assimilation

nonlabial changes to a labial

/bop/ for /boat/

other types of assimilation

Labial

velar

alveolar

nasal

Prevocalic voicing

voicing an unvoiced consonant when it precedes a vowel

Post vocalic devoicing

changing a voiced obstruent at the end of a word to a voiceless obstruent

prevocalic devoicing/ postvocalic voicing

atypical

reduplication

/wawa/ for water

same number of syllables

common process during first 50 words stage

Substitution Process

replacing one sound by another sound without being influenced by the surrounding phonemes

Stopping

substitution of a stop for a fricative/affricate

age of suppression varies by sound

Fronting

substitution of a more anteriorly produced phoneme

should stop around age 5 (other studies say 3:6)

Backing

substitution of a more posteriorly produced phoneme

Affrication

non-affricate becomes an affricate

affricates are /tʃ/ and /dʒ/

Deaffrication

fricative for an affricate

fricatives are:

/ʃ/, /ʒ/, /f/, /v/, /θ/, /ð/, /s/, /z/, /h/

Palatalization

sound produced as palatal

palatals are:

/ʃ/, /ʒ/, /tʃ, /dʒ/, /j/, /r/

Depalatazation

nonpalatal for a palatal

gliding

use of glide for another consonant

Glides are:

/w/, /j/

goes beyond age 5 up to age 7

Vocalization/Vowelization

vowel for liquid phoneme

Denasalization

nasal replaced by non-nasal homorganic
