The aim of this paper is two folds. First, the paper attempts to investigate prosody and discourse structure in Japanese spontaneous monologues by using the prosodic labels of the Corpus of Spontaneous Japanese (CSJ). The analyses of F0 peak trends and prosodic breaks confirmed previous findings in [1]. Secondly, the paper attempts to evaluate the validity of prosodic labels of the X-JToBI system that was adopted in CSJ (pitch-accents, boundary tones and break indices). The results of the analyses using three types of prosodic labels in the X-JToBI system provide evidence that the prosodic labels in CSJ can be useful for studies on discourse structures of Japanese spontaneous speech.
