배경 및 목적: 음절성 옹알이의 출현은 생후 1년 동안 일어나는 말 발달에서 가장 중요한 이정표이고 말-언어발달상의 문제를 예측하는 주요 요인이다. 본 연구는 아동의 가정에서 하루 동안 수집된 자료를 토대로 구개열과 일반아동의 음절성 옹알이의 발달을 종단적으로 살펴보고자 하였다. 방법: 구개열과 일반아동 각각 9명을 대상으로 LENA 녹음기를 이용하여 생후 4개월에서부터 21개월에 걸쳐 일정한 간격으로 초기 발성 자료를 4회기 수집하였다. 하루 동안 수집된 각각의 회기 자료에서 아동 발성이 가장 높은 5분 길이의 구간 20개를 선택하여 아동과 회기당 총 100분의 녹음자료를 들으면서 분석자가 발성을 판단하였다. 총 음절수, 음절유형수, 음절성 옹알이와 진음절성 옹알이 비율을 구하여 월령에 따라 집단 간 유의한 차이가 나타나는지 살펴보았다. 결과: 관찰기간 동안 총 음절수는 집단 간차이를 보이지 않았다. 13-15개월에 구개열 아동이 일반아동보다 기본 음절수가 유의하게 적었다. 13-15개월과 19-21개월에 음절성 옹알이와 진음절성 옹알이 비율에서 집단 간 유의한 차이가 나타났다. 논의 및 결론: 본 연구는 구개열 아동이 음절성 옹알이를 늦게 산출하고, 구개성형술을 받은 이후에도 일반아동과 비교해 음절성 옹알이 비율이 유의미하게 낮음을 보여주었다. 본 연구는 궁극적으로 구개열 아동을 위한 조기 중재의 중요성을 강조하고 있다.

Objectives: The emergence of canonical babbling reflects a critical advance in development of speech capacity in the first year, and late onset of canonical babbling appeared to be a predictor of later speech and language disorders. This study aimed to examine characteristics and changes in canonical babbling in children with and without cleft palate (CP) using all-day recordings in naturalistic environments. Methods: All-day home recordings using Language ENvironment Analysis (LENA) were obtained from 9 children with CP and 9 children without CP at four different time blocks from 4 to 21 months. Twenty 5-mintue segments with the highest child vocalization rate were extracted from each children’s LENA recording. Coders classified syllables as canonical and non-canonical syllables, syllables with glottal sounds, and syllables with glides. Group and age comparisons were conducted in terms of the number of each syllable type and canonical babbling ratios (CBR) at observed times. Results: The results indicated that there were no significant group differences in total number of vocalization and syllables across the observed times. Children with CP produced fewer canonical syllables than children without CP at 13-15 months of age. The group differences in the CBR and true CBR were significant at 13-15 months and at 19-21 months. Conclusion: This study suggests that children with CP show late onset of canonical babbling and group difference in the quality of babbling became evident even after surgical repair. This study highlights the importance of early intervention for children with CP.
