Table 2 - Phonological Processes

All children make predictable pronunciation errors (not really 'errors' at all, when you stop to think about it) when they are learning to talk like adults. These 'errors' are called phonological processes, or phonological deviations. In Table 2 are the common phonological processes found in children's speech while they are learning the adult sound-system of English.

Gliding of liquids ladder = wadder Liquids are replaced by glides.
Stopping ship = tip A stop consonant replaces a fricative or affricate.
