영어원어민들의 연속파열음에 대한 자연발화 연구: 벅아이 코퍼스를 중심으로

Abstract

The current study investigates durations of English consecutive stops found in word boundaries based on a spontaneous speech corpus called Buckeye Corpus. The consecutive stops were investigated based on four voicing types and three places of articulations. When two stops are adjacent, they typically share closure durations. The durations of the shared closure duration followed by VOT of the word-initial stops were measured as the durations of consecutive stops. It turned out that the voicing types were statistically significant in the durations of them. Voiceless pairs were the longest, voiced-voiceless pairs second-longest, voiceless-voiced pairs third-longest, and voiced pairs the shortest. The durations of consecutive stops were significantly different when word-final stops were alveolar stops and when word-initial stops were velar stops. This study also suggests that VOT has lost its role as a phonetic cue for places of articulations of word-initial stops.
