phonological process
Systematic sound changes that children use to simplify adult speech patterns during normal development.
Full Definition
Phonological processes are predictable, rule-based patterns of sound changes that typically developing children use to make adult speech sounds easier to produce. These processes include substitutions, omissions, and sound pattern changes that help children approximate adult speech while their motor and linguistic systems are still developing. Examples include fronting (saying 'tea' for 'key'), stopping (saying 'dop' for 'shop'), and cluster reduction (saying 'poon' for 'spoon'). Most phonological processes are suppressed or eliminated by specific ages, and persistent use beyond typical developmental timelines may indicate a phonological disorder requiring intervention.
Usage
Usage note: Distinguish from articulation errors, which are motor-based rather than pattern-based.
