| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | In this report, we propose a technique for cross-gender statistical singing voice conversion (SVC) with direct waveform modification based on spectrum differential (DIFFSVC). SVC makes it possible to convert voice timbre of a source singer into that of a target singer based on a statistical conversion function of acoustic features between these two singers. A traditional SVC framework usually degrades speech quality of the converted singing voice compared to that of a natural singing voice due to waveform generation with vocoder, which causes various errors. To address this issue, the DIFFSVC technique has been proposed as a high quality SVC framework for within-gender conversion by directly using an excitation signal of the input natural singing voice. To make it possible to also apply this SVC framework to cross-gender conversion, in this report, we apply F0 transformation of the excitation signal based on direct waveform modification to DIFFSVC. The experimental results demonstrate that the proposed cross-gender DIFFSVC framework significantly improves speech quality while while preserving the conversion accuracy of singer identity compared to the conventional SVC. | |
