초록
The current study investigated the effect of speaking style on the phonetic realization of Korean monophthongs in the productions of 20 native talkers. The talkers were asked to read a paragraph out loud as if speaking to either (1) a close friend or (2) a hearingimpaired or non-native listener. Each talker read the paragraph once in both conditions. The first condition was intended to elicit casual speech and the second condition clear speech. The acoustic realization of the monophthongs in each condition was analyzed in both the temporal and spectral domains. All vowels exhibited shorter duration in the casual speech. In the spectral domain, most vowels were less dispersed in casual speech, but some vowels did not display this pattern. These results suggest that speakers strengthen the acoustic salience of vowels when they expect difficulty in language processing on the part of the listener, and conversely exhibit vowel reduction in the opposite situation.
Abstract
The current study investigated the effect of speaking style on the phonetic realization of Korean monophthongs in the productions of 20 native talkers. The talkers were asked to read a paragraph out loud as if speaking to either (1) a close friend or (2) a hearingimpaired or non-native listener. Each talker read the paragraph once in both conditions. The first condition was intended to elicit casual speech and the second condition clear speech. The acoustic realization of the monophthongs in each condition was analyzed in both the temporal and spectral domains. All vowels exhibited shorter duration in the casual speech. In the spectral domain, most vowels were less dispersed in casual speech, but some vowels did not display this pattern. These results suggest that speakers strengthen the acoustic salience of vowels when they expect difficulty in language processing on the part of the listener, and conversely exhibit vowel reduction in the opposite situation.
