Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes automatic prosodic context labeling of training data for synthesizing expressive speech in HMM-based speech synthesis framework by focusing on emphasis expression. We have proposed unsuper- vised labeling technique with emphasis context using the property of the difference between original and generated F0 patterns. In this approach, there is a problem that the threshold which is used to judge whether a phrase is emphasized or not has to be pre-determined. To overcome this problem, we propose a technique for determining an optimal threshold automatically based on a behavior of F0 pattern in emphatic speech. Experimental results show that the proposed technique gives a similar result to the labeling obtained by subjectively and the emphasis expression is well reproduced in synthetic speech.
