The aim of this study is to find out whether close relationship between the prespeech vocalization and later speech-language development of normally developing children can be also found in the children with cleft palate, through the literature review on the studies on the phonological development and expressive language capability of the cleft palate children. Several studies compared the prelinguistic vocal development of babies with unrepaired cleft palate and age-matched peers to find out the variables which may affect the relationship between the prelinguistic phonetic characteristics and later phonological-lexical development of the cleft palate children. As results, babies with cleft palate had smaller canonical babbling ratio than their age-matched peers and the number of babies who reached the canonical babbling stage was limited. Also, the consonant inventories of cleft palate children were smaller, with fewer oral stops noted. Compensatory articulation like glottal stops occurred more frequently in the vocalization of babies with cleft palate. There may exists more complex relationship between early speech and later speech and language outcomes for children with cleft palate. It seems that good performance of prespeech babbling does not always result in good performance later on. Instead, it is likely that there are other variables that may influence later speech and/or language skills of the cleft palate children. Some possible explanations for why babies with cleft palate are delayed in babbling and limited in phonetic(phonological) skills should be explored.
