벅아이 코퍼스를 통해서 본 영어원어민들의 유무성 유형에 따른 단어경계파열음 발화 연구

Abstract

In the currunt study investigates how the voicing types influence durations of homorganic word boundary stops. For this purpose, Buckeye speech corpus, which contains numerous spontaneous speech materials, were used. To measure the word boundary stops such as /p#p/, /b#p/, /p#b/, and /b#b/, stop closures of both word-final stops and those plus VOTs of word-initial stops were selected. The results were analyzed based on voicing types such as /voiceless#voiceless/, /voiced#voiceless/, /voiceless#voiced/, and /voiced#voiced/, and showed that word-boundary stops with word-initial voiceless stops were longer than those with word-initial voiced stops due to the VOT differences, and those with alveolar stops were shorter than those with bilabial and velar stops. In addition, the closure durations of the word-final stops were not statistically significant in the durations of word-boundary stops due to the fast rate of the spontaneous speech.
