HMM-based speech synthesis can generate highly natural prosody, but there is a problem that the pitch patterns represent the accent different from the designation might be generated. In this paper, for the purpose of reducing the error of accent caused by abnormality of pitch pattern outlines in prosody generated by HMM, we propose the learning method of prosody models introduced two-stage decision tree clustering. The set of questions to be used in the first stage of clustering is configuring by the only questions about pitch pattern outlines. Then, the tree structure near the root node is constructed with only the nodes that are split by the question about pitch pattern outlines. As a result of evaluation experiments, we confirmed that the proposed method decrease the error of accent in prosody generation by HMM by half with the decision tree has the same sized structure of the conventional method. |
