At what age should phonological processes typically be eliminated?

Phonological processes are patterns of sound errors that children use as they develop their speech and language skills. Typically, certain phonological processes are expected to be present in children at certain ages, but there is a point where these processes should naturally diminish as part of the child's speech development.

By the age of 4, most children have usually begun to eliminate many of the common phonological processes. This includes simplifications like fronting or stopping, which are more prevalent in younger children. While it is not uncommon for some phonological processes to still be present in certain children beyond age 4, it is generally expected that a typical child will have significantly reduced or eliminated these patterns by that age.

Understanding these developmental milestones is important for identifying potential speech sound disorders, as speech that retains these processes beyond age 4 may warrant further evaluation or intervention. Recognizing that by age 4, children should be moving towards more adult-like speech patterns helps in setting appropriate expectations for their speech development.
