Substitution Speech Sound Errors
Substitution Speech Sound Errors
Substitution errors occur when a child swaps one sound with another, usually because the original sound is difficult for them to say. These patterns are a normal part of speech development as children learn how to produce more complex sounds. The table below has some of the most common ones.
Age of Elimination
Age of elimination refers to the age when we expected most of the speech sound errors to have disappeared. Below is a table which shows when we typically see sound errors disappear from a child’s speech.
Substitution patterns are typical in early speech development and usually resolve as a child’s speech skills improve. Most children outgrow these patterns by the age of 3 to 6 years.
