Cleft palate speech is an overarching term to describe the speech of individuals with cleft palate +/– cleft lip (CP/L) and other velopharyngeal disorders. Individuals with CP/L may have articulation and phonological disorders as well as velopharyngeal insufficiency (VPI) due to differences in the structure and function of the velopharyngeal mechanism. This entry begins with a brief discussion of the speech effects of cleft palate and cleft lip, followed by a section on assessment. The entry also touches on speech development of young children with CP/L, the prevalence of speech characteristics in children with CP/L, and Speech–Language intervention for children with CP/L.
