A Study of Information Structures and Prosody Changes in the Double Subject Constructions

The purpose of this paper is to observe the prosody changes according to information structures in the Korean double subject constructions. The first noun phrases, NP1, in the double subject constructions, can function as focus, topic, contrast focus, and contrast topic, from a perspective of the information structures, respectively. This paper identifies their differences shown statistically and phonetically. After calculating the differences between the mean value of the fundamental frequency (F0) of the first vowel of NP1 and that of NP2 (NP1 F0-NP2 F0) in the relevant information structures, it is examined whether the differences would be significant statistically, using two-way ANOVA. Furthermore, this paper identifies whether the AP (accentual phrase) boundary between the two noun phrases would be dephrased, whether the pitch contour between them lowered or whether the prominence between them would occur.
