초록

The purpose of this study is to compare the VOTs of Korean stops when they are placed in word-initial position and in an intervocalic environment word- medially. This investigation is implemented by measuring the VOT of isolated words spoken by Daegu Korean speakers in their twenties. Comparisons of the VOTs between word-initial and word-medial positions support the claim that the aspirated stops as well as the plain stops are the targets of the weakening process in the intervocalic environment in Korean, although the ratio of the VOT reduction of the plain stops in an intervocalic environment against a word-initial position remains by far greater than that of the aspirated stops. Findings in this study also include the fact that there is no variability in the VOT between male and female speakers in word-initial position. In the intervocalic environment, however, the VOT reduction rate turned out to be higher in male speakers than in female speakers, and this lends supporting evidence to the claim that male speakers are more prone to the weakening process than female speakers. Furthermore, the results of the acoustic analysis indicate that velar stops have longer VOT than bilabial or alveolar stops and that the aspirated stops have longer VOT than the plain or the tensed stops, regardless of their position in a word or the speaker's sex. Unlike some previous studies where alveolars are reported to be longer than bilabials, however, the statistical results in this study do not show significant difference between these two places of articulation.
