Phonological Development

The process by which children learn to produce and organise the speech sounds of their language, progressing from early cooing and vowel-like sounds through canonical babbling (consonant-vowel syllables) to recognisable words and complex phonological patterns. Phonological development follows a broadly predictable sequence: reflexive sounds give way to cooing (2-3 months), then babbling (6-10 months), first words (around 12 months), and increasingly complex sound combinations through the preschool years. Children with disabilities affecting motor control, hearing, cognitive development, or neurological function may show delayed or atypical phonological development. Early identification of atypical vocalization patterns — such as delayed onset of canonical babbling — is a critical indicator for speech and language intervention.
