Abstract (in Japanese) (See Japanese page) 
(in English) This paper proposes an extended context set for generating the prosodic variability of spontaneous speech in HMM-based conversational speech synthesis. Since the conventional context set used for HMM-based reading-style speech synthesis is insufficient for conversational speech synthesis, we introduce new contexts derived from the Corpus of Spontaneous Japanese. We compare the context sets with and without newly introduced contexts, and the experimental results show that the contexts about phone prolongation and X-JToBI tone tier label are effective. Furthermore, we examine the stopping criteria for decision-tree clustering and the automatic estimation of a part of contexts for practical applications.
