초록

이 연구의 목적은 한국어를 사용하는 성인에서 성별에 따른 비음도의 차이가 있는지 알아보고, 후천적 구개부 결손환자의 보철치료를 위한 기초자료로 사용을 위해 정상 비음도를 획득하는 것이다. 음성언어 표본으로 선정된 단순모음, 이중모음, 반복자음, 그리고 비음의 비율이 높은 문장, 비음의 비율이 중간인 문장, 비음의 비율이 낮은 문장에 대해 비음도의 평균과 표준편차를 구하고 남녀간의 차이가 있는지를 t-test와 Mann-Whitney test를 이용하여 분석하였다. 피실험자들은 서울 경기 지역에 거주하는 남자 15명과 여자 15명으로 구성되었고 이들 중 남자 피실험자들의 나이는 24세에서 38세까지 분포하였고 평균나이는 26.3세였다. 여자 피실험자들의 나이는 19세부터 33세까지 분포하였고 평균나이는 24.4세였다. 비음측정기 Nasometer II 가 실험에 사용되었다. 연구의 결과로 /이/ 모음을 포함하는 일부 반복 자음을 제외하고는 모음, 반복자음, 문장을 이용한 음성언어표본에서 남녀 간 비음도의 유의성 있는 차이가 발견되지 않았다. 비음측정기는 음성언어표본이 달라짐에 따라 비음도의 유의한 차이를 나타내었다.
