Abstract

Sentence repetition is a way of evaluating speech sound production to improve the limitation of word tests and spontaneous speech analysis. Speech sounds produced by children can be evaluated using several indicators. This study examined the progression of the percentage of correct consonants-revised (PCC-R) and phonological whole-word measure in different age and gender groups after setting consonants in various vowel contexts and implementing sentence repetition tasks that were designed to give all phonemes the chance to appear at least three times. For this study, 11 sentence repetition tasks were applied to 535 children aged 3 to 7 across the country, after which the resulting PCC-R and whole-word measure were analyzed. The study results showed that all the indicators improved in older age groups and there were significant differences depending on age, however, no significant differences dependent on gender were found. The sentence repetition conditions data used in this study were collected from across the country, and the age difference between each age group was six months. This study is noteworthy because it collected a sufficient amount of data from each group, highlighted the limitation of the word naming and the spontaneous speech analysis, and suggests new criteria of evaluation through the analysis of each whole-word measure in sentence repetition, which was not applied in previous studies.

아동이 산출하는 말소리를 평가할 때 단어와 문장을 유도하여 산출한 말소리를 분석하고, 자발화를 이용하여 분석하기도 한다. 단어 검사와 자발화 검사의 한계를 보완할 수 있는 평가 방법으로 문장 따라말하기 과제가 있다. 문장 따라말하기 과제를 통한 아동의 말소리 평가는 자발화와 유사한 특성을 보이면서 단어와 같이 제한된 시간 안에 다양한 음소를 평가할 수 있다. 본 연구에서는 다양한 모음문맥에서 자음을 배치하고 모든 음소가 3회 이상의 출현 기회를 가질 수 있도록 계획된 11개의 문장 따라말하기를 통해 연령과 성별에 따라서 단어단위 음운지표와 개정자음정확도의 발달을 살펴보았다. 전국에 거주하는 3세부터 7세까지 아동 535명을 대상으로 UTAP2에 새롭게 포함된 11개 문장 따라말하기 과제를 실시하였다. 말소리발달을 평가할 수 있는 지표 PCC-R, PWC, PMLU, PWP을 구하였다. 아동은 연령별 6개월 단위로 10개의 집단을 구분하고 각 지표에 대해 연령집단과 성별에 따른 차이를 분석하였다. 연구 결과, 모든 지표에서 연령이 증가함에 따라 수치가 상승하였으며 연령집단 간 차이는 유의하였다. 성별에 따른 차이와 연령과 성별의 상호작용효과는 유의하지 않은 것으로 나타났다. 본 연구는 전국에서 자료를 수집하였고, 연령집단을 6개월로 나누어 보았으며, 집단별 데이터를 충분히 수집하였다는 점과 단어와 자발화 검사의 한계점을 보완할 수 있는 문장 따라말하기라는 새로운 말소리 평가 방법의 연령별 준거 자료를 제시하였다는 측면에서 의의가 있다.
