| Abstract(in English) | Our aim is to realize a new vocoder, which can resolve various constraints imposed on source-filter model and deal with speech waveform directly. In this study, we propose a method of synthesizing speech waveforms with WaveNet, which was a recently proposed neural network for generating audio signal waveforms, by using existing vocoder parameters as input auxiliary features. It is expected that these parameters are effective for auxiliary feature of waveform generation, because they are based on source-filter model. In the experiment, parameters of mel-cepstrum vocoder were selected as target, and quality of synthesized speech was objectively evaluated by SNR (Signal-to-Noise Ratio) and SDR (Signal-to-Distortion Ratio). From the results, it was confirmed that the sound quality was significantly improved for SNR and proposed method was effective. |
