| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this paper, we propose a postfilter based on a modulation spectrum for high-quality HMM-based speech synthesis. An over-smoothing effect that is observed in the generated speech parameter sequence is a main cause of quality degradation in HMM-based speech synthesis. A Global Variance (GV) is well-known as a better feature to capture the over-smoothing effect, and an effectiveness of the parameter generation algorithm considering the GV have been confirmed. However, the quality gap between natural speech and synthetic speech is still large. In this paper, we introduce a Modulation Spectrum (MS) of speech parameter trajectory as a new feature to effectively capture the over-smoothing effect. The generated speech parameter sequence is filtered to compensate its MS. Experimental results show that quality improvements by the proposed methods applied to spectral and F0 components is yielded compared with conventional HMM-based speech synthesis. |
