초록
Conversational speech has received considerable attention in recent years, but many instrumental studies have focused on heavily resourced languages and the phonetic reduction in conversation. To diversify and expand on conversational speech research, this study examines the unique system of stop contrast in Korean and their acoustic cues in spontaneous phone conversations. The study investigates some key acoustic properties of intervocalic Korean stops in casual speech, adding to the growing body of research on conversational speech. Korean stops from careful reading and casual conversation show greater acoustic variability in conversation, as previously noted. Despite the phonetic variability in acoustic signals, conversational Korean stops contrast with one another in three acoustic dimensions: intensity difference, VOT, and closure duration, allowing some cues to enhance the stop contrast in conversation. The findings point to manner-specific adjustments in spontaneous Korean stops, and suggest that variability in conversational speech yields both phonetic reduction and enhancement.
Abstract
