구어 담화표지 ‘어디’의 운율 특성

Abstract

The purpose of this study is to analyze the prosodic features of the discourse marker "eodi (어디)." Using speech data collected from 10 (F5, M5) participants, prosodic features. such as tonal pattern, duration, and utterance rate of "어디", were analyzed based on their functions. The discourse marker "어디" is located at the beginning, middle, and end of the utterance, and can be presented as a single utterance. The specific tonal pattern of the discourse marker "어디" in each function can be noted at IP boundary tone, which is realized on the IP-final syllable "di (디)": H+L% (utterance initiation), L+L% (maintenance of utterance), L+H% (positive attitude, only in single utterance), L+HL% (negative attitude), and L+LH% (emphasizing). The average length of the discourse marker "어디" was the longest in the function of maintaining utterance (454 ms) and the shortest in positive attitude (267 ms). The study results also show that speakers modulate the speech rate of the discourse marker "어디" in their own utterance by lengthening or shortening the duration of each syllable.
