In addition to these processes there are some atypical processes which children may present with and are not seen in typically developing children. If your child is still doing some of these processes a significant time after the appropriate age of elimination, it is likely that your child has a ‘phonological (speech sound) delay’. When /r/ becomes a /w/ and /l/ becomes a /w/ or y sound When /th/ sounds are replaced with /t/ or /d/ When there are 2 consonants in separate places in a word, and one consonant changes to be the same as the other When two consonants together, referred to as a cluster, are reduced to one consonant by itself, referred to as a singleton. When the unstressed, or ‘weak’ syllable is deleted from the word When /sh/ /ch/ and j sounds are replaced with sounds such as /t/ /b/ /d/ and /p/Į.g. When /v/ and /z/ is replaced with /b/ or /d/ When /f/ and /s/ is replaced with /p/ or /t/Į.g. When sounds made by the tongue touching the roof of the mouth such as /sh/ are replaced with front sounds such as /s/ When back sounds such as /k/ and /g/ are replaced with front sounds such as /t/ and /d/Į.g. When the consonant at the end of the word is left off When a voiced consonant at the end of a word like /b/ or /d/ is substituted with a voiceless consonant like /p/ or /t/ When a voiceless consonant at the start of a word like /p/ or /t/ is substituted with a voiced consonant like /b/ or /d/ These processes have age norms which indicate the age at which a ‘typically developing’ child will stop doing them by. There are some typical ‘processes’ that children will do, referred to as ‘natural phonological processes’. It is normal for young children to say sounds incorrectly, and it is an indication that their speech sound systems are developing and maturing.

This can make it difficult for people to understand your child and can impact on your child’s confidence, socialisation with other children, and motivation to communicate.

You may have noticed that your child has difficulty pronouncing some sounds and may do things such as substitute one sound for another, leave sounds out, add on sounds, or change a sound.
