Abstract(in English) | An improved set of context labels was proposed for HMM-based speech synthesis of Japanese. The conventional labels include those related to sentence length, such as number of mora and order of breath group. When handling sentences with various lengths, label numbers increase, which causes the "explosion" of label combinations. Furthermore, in Japanese, labels related to prosody are mostly designed based on the unit "accent phrase, " whose definition is somewhat unclear; it is not uniquely defined for a given sentence, but also is affected by other factors such as speaker identity, speaking rate, and utterance style. Therefore, reliable prediction of accent phrase boundaries for sentences included in the ti ainmg speech corpus comes difficult, leading to occasional mismatches in the predicted boundaries and prosodic features. In the proposed labels, "bunsetsu" is used instead as the basic unit for prosody. Also, we only view its relations with preceding and following "bunsetsu's." By doing so, the labels not related to the sentence lengths are obtained, with easier automatic prediction of labels only from sentence representations. Validity of the proposed labels was shown through a listening experiment of synthetic speech. |
