+ Checklist for Development of Speech Sounds in Children

other topics: click a “category” or use search box

This checklist shows at what age 90% of boys and girls can articulate the English consonants correctly, whether they are at the beginning, middle or end of a syllable.

Vowels are correctly produced by the age of three.

Note: All children do not develop at the same time and in the same way, so we cannot expect correct speech from every child in the primary grades.  If you have questions about this or other speech/language milestones, contact your school’s speech-language pathologist.
