| Abstract(in English) | This paper proposes a novel objective evaluation technique for statistical parametric speech synthesis. A novel point of the proposed technique is that it utilizes the association between dimensions within the spectral features. We first analyze the subjective scores obtained with respect to the associations of spectral features of natural and various synthesized speech by using a maximal information coefficient (MIC). The analysis results show that the scores improve with weaker association. We then propose the proposed objective evaluation index, which uses a voice conversion technique to detect the associations for each speech. We perform subjective and objective experiments and evaluate the performance results obtained by comparing them with the obtained subjective scores and the conventional objective evaluation index, i.e., mel-cepstral distortion. The results indicate that our proposed objective evaluation index is more effective than the mel-cepstral distortion. |
