The relationship between early speech and later speech and language performance for children with cleft lip and...

This study examined the relationship between speech measures at presurgery/9 months and postsurgery/13 months and speech and language performance at 21 months for children with cleft lip and palate and their noncleft peers. Comparisons were also made between the speech and lexical development of children with cleft lip and palate and noncleft children at 21 months of age. The participants included 30 children; 15 with cleft lip and palate and 15 noncleft children. Results revealed differences between the groups for several measures of speech and lexical development at 21 months. For the children with cleft palate, correlational analyses suggested that true stop production, both immediately before and after palatal surgery, was positively correlated with a majority of the speech production measures at 21 months. At postsurgery/13 months, true stop production was related to later vocabulary development, and size of true consonant inventory was related to all measure of speech production and one measure of lexical development at 21 months. For the noncleft group, true canonical babbling ratio at 13 months was the only measure that was significantly correlated with any of the speech and/or language measures at 21 months. The impact of clefting on prelinguistic and later speech and language skills is discussed.
