What are Phonological Processes?

Phonological processes are patterns of sound errors that typically developing children use to simplify speech as they are learning to talk. 

A phonological disorder occurs when phonological processes persist beyond the age when most typically developing children have stopped using them or when the processes used are much different than what would be expected.

Age of Elimination

The age at which phonological processes are eliminated is a one year range. For example if the age of elimination is 5, the child has until 5 years 11 months to eliminate the process. Therefore, active phonological processes are not recommended to be targeted in therapy until one year following the age of elimination.

The ages at which phonological processes are eliminated are highly variable among children. As a result the age of elimination should be used as a reference only when considering the need for intervention.

The age shown on this FREE downloadable chart and poster at which Phonological Processes are eliminated is based on the following research:

What SLPs are saying...

“There’s not a day that goes by that I don’t reference this chart. It’s seriously a life-saver for a busy school SLP! I reference this chart for screenings, assessments, report writing and during IEP meetings when I am explaining processes to parents, teachers and other staff. I truly can’t live without it!”

"This phonological processes chart is a must-have for SLPs and parents alike. I use it as a quick reference throughout the assessment process. I also provide it as a resource for my parents to help them understand their child’s speech development and the challenges they may be facing. The definitions and examples provided for each phonological process make it easy to understand."

“This is my favorite resource for phonological processes! I love having all the definitions together in a clear, easy to read format. It is a great tool for my reference and an excellent resource to share with parents. I use it almost every day! Thank you Little Bee! ”
