The purpose of this report was to document phonological changes in a pair of identical twin boys diagnosed as language delayed. The boys were not enrolled in direct treatment, but were evaluated four times between the ages of 3;5 and 4;9. Speech samples were analyzed for phonetic inventories, phonological process use, and syllabic shapes. Observed changes in their speech generally followed normal developmental patterns.
