초록

이 연구의 목적은 한국어 이중모음 /ㅛ/가 다양한 언어학적 환경에서 어떠한 발음 변이 양상을 보이는지 밝히는 것이다. 특히 음성적 변이와 분포 범위의 연관성에 주목하여 /ㅛ/의 발음 양상을 논의하였다. 서울코퍼스의 여성 화자 10명의 발화에서 나타난 /ㅛ/의 운율적 위치(단음절, 어절 초, 어절 중, 어절 말)와 어휘 부류(내용어, 기능어)를 분석하였다. 각 환경에서 /ㅛ/의 출현 빈도를 파악한 결과, 운율적 위치에 따라 어휘 부류와 발음형 실현이 달라지는 양상을 보였다. 음향 분석을 통해 기능어에서 나타나는 /ㅛ/에서는 음성적 약화가 빈번하게 일어나는 것을 확인하였다. 어휘 부류는 /ㅛ/의 평균적인 음가를 달라지게 하지는 않았지만 개별 토큰의 분포 양상에서는 차이가 발견되었다. 이를 통해 언어학적 환경이 모음의 음성적 분포 양상에 영향을 미친다는 것을 알 수 있었다.

The purpose of this study is to determine how the Korean diphthong /jo/ shows phonetic variation in various linguistic environments. The pronunciation of /jo/ is discussed, focusing on the relationship between phonetic variation and the distribution range of vowels. The location in a word (monosyllable, word-initial, word-medial, word-final) and word class (content word, function word) were analyzed using the speech of 10 female speakers of the Seoul Corpus. As a result of determining the frequency of appearance of /jo/ in each environment, the pronunciation type and word class were affected by the location in a word. Frequent phonetic reduction was observed in the function word /jo/ in the acoustic analysis. The word class did not change the average phonetic values of /jo/, but changed the distribution of individual tokens. These results indicate that the linguistic environment affects the phonetic distribution of vowels.
