어두 폐쇄음의 발성 유형 지각에서 나타나는 방언 간 차이－ 서울 방언과 대구 방언의 비교를 바탕으로－

Abstract

The aim of this study is to investigate some dialectual differences in the perception of the phonation types in the word-initial stops through Seoul and Daegu dialect. A perception test was designed to manipulate the VOT and F0 of the following vowel, noted for the acoustic cues to discriminate among the phonation types. The results of this study show that there are different interactions between VOT and F0 in the two dialects. In Seoul dialect, F0 is the acoustic cue to distinguish lenis and other two kinds of phonation types, and VOT is to distinguish fortis and aspirated, belonging the same class through VOT. On the other hand, VOT is to distinguish fortis and other two kinds of phonation types, and VOT is to distinguish lenis and aspirated, belonging the same class through F0 in Daegu dialect. It seems that these differences come from the tones in Daegu dialect. Because the F0 functions as the cue of tone distinction unlike Seoul dialect, VOT functions as the important cue to distinguish the phonation types in Daegu dialect.
