Abstract

This study aimed to investigate regional differences in the development of speech production in Korean children. A total of 619 children aged 2 to 7 years from the Jeolla, Seoul/Gyeonggi, Chungcheong, and Gyeongsang areas were included in this study. The subjects were assessed with the UTAP2 word-level test. In PWC, PMLU, and PWP, the performance was significantly lower in Gyeongsang at 2 years 11 months and in Jeolla and Chungcheong at 3 years 5 months than in Seoul/Gyeonggi. The total PCC of Gyeongsang and Chungcheong and UTAP PCC of Chungcheong were significantly lower at 2 years 11 months compared with those of Seoul/Gyeonggi, while Jeolla and Chungcheong showed significantly lower total PCC and UTAP PCC than Seoul/Gyeonggi at 3 years 5 months. However, no regional difference was observed in any indicators after the age of 3 years 6 months. These results suggest that there are regional differences in the ability to produce speech sounds at a very young age, and that the differences can be explained by the differences between Seoul/Gyeonggi and the other provinces rather than by the individual characteristics of specific regions.

본 연구의 목적은 우리나라 아동들의 말소리산출 발달에 지역적 차이가 존재하는지를 알아보고자 하는 것이다. 2세 후반부터 7세에 해당하는 전라, 서울경기, 경상, 충청 지역의 아동 619명이 본 연구에 참여하였고, 대상자들에게 우리말 조음음운평가2의 단어수준 검사를 진행하였다. 수집된 데이터에 대해 지역 및 연령에 따른 단어단위정확률(PWC), 평균음운길이(PMLU), 단어단위근접률(PWP), 전체 자음정확도(Total PCC), UTAP 자음정확도(UTAPPCC)를 비교 분석하였다. 연구결과 단어단위 지표인 PWC, PMLU, PWP에서는, 2세 후반의 경우 경상도 지역에서, 3세 초반의 경우 전라도와 충청도 지역에서 서울경기 지역보다 수행력이 유의하게 낮았다. 그러나 3세 후반부터는 어떤 단어단위 지표에서도 지역 간 차이가 관찰되지 않았다. 분절음 차원의 지표인 PCC에서는, 2세 후반의 경우 Total PCC에서 경상도와 충청도가, UTAP PCC에서 충청도가 서울경기 지역보다 수행력이 유의하게 떨어졌고, 3세 초반의 경우 두 지표 모두에서 전라도와 충청도가 서울경기보다 수행력이 유의하게 떨어졌다. 그러나 3세 후반부터는 Total PCC와 UTAP PCC 모두에서 지역 간 차이가 나타나지 않았다. 이러한 결과는 어린 연령의 경우 말소리산출 능력에 국내의 지역 간 차이가 존재하며, 그 차이가 특정 지역의 특성이라기보다는 서울과 지방의 차이로 설명될 수 있음을 시사한다.
