| Abstract(in English) | This report proposes a novel unit selection algorithm for Japanese Text-to-Speech (TTS) systems. Since Japanese syllables consist of CV (C : Consonant, V : Vowel) or V, except when a vowel is devoiced, CV units are generally used in concatenative TTS systems for Japanese. However, synthetic speech based on the CV-unit concatenation sometimes have discontinuities in case of V-V concatenation. In order to alleviate such discontinuities, longer units (CV^* or non-uniform units) have been proposed. However, the concatenation between V and V is still unavoidable. To address this problem, we propose a novel unit selection algorithm that incorporates not only phoneme units but also diphone units. The concatenation in the proposed algorithm is rerformed at the vowel center as well as at the phoneme boundary. Results of evaluation experiments clarify that the proposed algorithm outperforms the conventional algorithm. |
