Abstract
Objectives: Canonical babbling (CB) is a major milestone in development of speech capacity in the first year and known as a significant predictor of later speech and language development. The purpose of this study was to examine canonical babbling development in children with cleft palate (CP) after cleft palate surgery compared to children without CP.
Methods: Ten children with CP and 10 children without CP at 13-15 months of age participated in the study. Coders were analyzed twenty 5-minute segments with the highest child vocalization rate extracted from each child’s all-day home recording using Language ENvironment Analysis. Child vocalizations were determined based on syllable unit and each syllable was categorized as canonical and non-canonical syllables, syllables with glottal sounds, or syllables with glides. The number of each syllable type, canonical babbling ratios (CBR), and true canonical babbling ratio (TCBR) were compared between groups.
Results: The results showed no significant group differences in total number of vocalization and syllables. Children with CP produced fewer canonical syllables than children without CP and the group differences in the CBR and TCBR were significant.
Conclusion: This study suggests that children with CP show a limited development in canonical syllables even after cleft palate surgery and emphasizes the significance of followup services to monitor speech-language developmen for children with CP.
