초록
This study aims to account for the variation among VOT, F0 and vowel durations of English voiced and voiceless stops. It provides analysis on English stops comparing English native and Korean speakers and shows the phonological transfer between English and Korean stops produced by Korean speakers. The results of the acoustic analysis indicate that the differences between voiced and voiceless stops in terms of VOT and F0 are statistically significant in both speaker groups. It turned out that the VOT values of the voiceless stops produced by native speakers were two times as high as Korean speakers. However, the F0 values between the voiced and voiceless stops produced by native speakers turned out to be overlapped. This suggests that native speakers rely on the VOT values more than on the F0 values. As for the vowel duration, the duration of following vowels was longer than that of Korean speakers. The three parameters of the English voiced and voiceless stops produced by the Korean speakers were similar to those of the Korean aspirated and lenis stops, which suggests that Koreans are not good at putting stresses on English stops.
Abstract
This study aims to account for the variation among VOT, F0 and vowel durations of English voiced and voiceless stops.

It turned out that the VOT values of the voiceless stops produced by native speakers were two times as high as Korean speakers. However, the F0 values between the voiced and voiceless stops produced by native speakers turned out to be overlapped. This suggests that native speakers rely on the VOT values more than on the F0 values. As for the vowel duration, the duration of following vowels was longer than that of Korean speakers. The three parameters of the English voiced and voiceless stops produced by the Korean speakers were similar to those of the Korean aspirated and lenis stops, which suggests that Koreans are not good at putting stresses on English stops.
