- The development of phonology
- Vegetative Stage (0-2 months)
- Before babies understand meaning they begin to make sounds
- Crying is seen as a response to an internal stimulus, proven to produce physiological changes in adults
- 4-7 months
- Features include cooing, first laughter and changes in pitch and loudness
- 6-9 months
- Beginning of phonemic expansion, as voice box develops and muscular control increases, the baby's capacity to produce sounding becomes more wide-ranging and complex
- Features include babbling, extension of sounds to imitate syllables and repeated patterns
- The baby undergoes phonemic contraction, process by which they cease to be potentially international and their sounds are reduced to the sounds of their own language
- Reduplicated monosyllables also become frequent, where babies produced combinations of sounds which may resemble adult speech, eg. 'baba'. Variegated babbling next stage from cooing
- 9-12 months
- After babbling, begin to produce sounds out of context: utterances known as proto-words (require pragmatic understanding)
- Vowels easier to pronounce than consonants, master 2/3 of consonants by about 30-40 months
- Consonant sounds such as the bilabial 'b' come first. Consonant clusters more challenging for 1-2 year old infants, may omit, transpose or reduce them. Capacity to form specific phonemes not yet in place.
- Virtuous Errors
- ADDITION: known as diminutives, reduplication and addition of sounds such as 'Moo moo'.
- SUBSTITUTION: method of simplification, replacing harder sounds with easier ones eg. 'big' for 'pig' or 'fin' for 'thin' (Fis phenomenon). Assimilation different kind of substitution, child repeats a neighbouring sound rather than using easier one eg. 'doggie' becomes 'goggie'.
- DELETION: 'Pi' for 'Pig' or 'ca' for 'cat'. Unstressed syllables may be removed eg. 'banana' becomes 'nana'. Consonant clusters may be reduced: 'nail' for 'snail'.
- Vegetative Stage (0-2 months)
