Oh, Mira. (2020). Longdistance effect of the APinitial consonants on interrogativefinal boundary tones in Chonnam dialect of Korean. The Linguistic Association of Korea Journal, 28(4), 51-75. This study explores the factors which affect the shapes of boundary tones in Korean interrogatives. 26 Chonnam speakers produced three types of interrogatives in Korean, (i.e., simple polar questions, whquestions, and indefinite pronoun questions) under variation in verbinitial consonants and question endings. A phonetic analysis of their production reveals three results. First, the initial segment of the Intonation Phrase (IP)final Accentual Phrase (AP) plays a significant role in determining the shapes of boundary tones. Second, the distribution of various boundary tones is different across the three types of interrogatives in Korean. Third, the lexical ending forms also condition the shapes of boundary tones. I propose that the APinitial consonant effect weighs more than the constraints for different types of interrogatives, which are in turn more weighted than the effect of the ending form. I test the validity of the proposed weighted constraints by the learned grammar in the Maximum Entropy Model based on the frequency of each boundary tone. This study shows that the differently weighted factors interact to produce various boundary tones in Korean interrogatives. |
