Phonological Development Notes


The Two Main Stages:
1. Learning to articulate consonants, vowels, syllables, words
2. Learning to represent words

0- 3 months:
  • Birth cry and then the differentiated cry
  • Reflexive sounds - produces a glottal catch and vowels
  • Coos and gurgles
  • Blowing bubbles - learning muscle control
1 - 2 years:
  • Sentence like intonation
  • Echolalia - repetition
  • Can understand some words if in the correct context
  • Want to pair vowels with consonants, eg. dada rather dad
3-4 years
  • Mastering a lot of sounds but may replace some sounds with ones that are easier to form, eg. ‘f’ not ‘th’
  • Intelligible use of language
Phonological Development Terms:
  • Cluster Reduction:
    - delete consonant combinations, e.g. ‘play’ spoken as ‘pay’
  • Syllable Reduction
    - The deletion of a syllable from a word containing two or more syllables.
    - The deletion usually occurs in the unstressed syllable.
  • Consonant Simplifications (Use a simpler consonant for a more difficult one)
Fronting: consonants are produced at the front of the mouth are easier than sounds produced further back, e.g. ‘d’ & ‘t’ are easier than ‘g’ or ‘k’, e.g. ‘got’ turns to ‘dot’
Stopping: sounds that stop airflow are easier than ones that restrict it ‘t’, ‘d’ are easier than ‘s’, ‘z’, ‘sh,’ ‘p’ and ‘b’ are easier than ‘f’ and ‘v’,                  (e.g. ‘foot’ as ‘put’)
- Gliding: replace ‘r’ and ‘l’ with ‘w’ (e.g. ‘rock’ spoken as ‘wo(ck)’)
  • Consonant assimilation
    - Make one sound the same as, or similar to, another in the word e.g. ‘dark’ pronounced as ‘guck’)
  • Diminutives
    - Morphemes attached to simple words, eg. dog becomes dog-y
    - They imply smallness
  • Reduplicated Babbling
  • Final Consonant Deletion
    - Leaving of the last consonant eg. stoppin’
  • Prevocalic voicing
    - The voicing of an initial voiceless consonant in a word.
  • Postvocalic devoicing
    - The devoicing of a final voiced consonant in a word.
