강세 충돌 해소의 음성학적 실태 연구

초록

The present study examines the phonetic realization of vowels in the avoidance of stress clash. This study compares a 5 syllable phrase which shows stress movement, with a 4 syllable word which has stress on the right foot. 5 male native speakers and 5 female native speakers read 16 sentences with words and phrases. Pitch declined in the third syllable compared to the first syllable in phrases (σ1>σ3). Correspondingly, pitch in the third syllable of a phrase was lower than that of a word. Intensity in the first and the third syllable of a phrase was similar (σ1≒σ3) and there was no significant intensity change in the third syllables between a word and a phrase. As a result, pitch reflected the effect of stress clash and showed stress shift and stress deletion in the manner of an acoustic value decrease, achieving the goal of avoiding stress clash. Intensity, on the other hand, maintained the periodical alternation (sw sw) and did not show the grid lowering in the manner of an acoustic value decrease.
