| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper describes a new method of voice conversion, which aims at character conversion based on eigenvoice GMM (EV-GMM) approach. Using an eigenvoice space built from 273 speakers and training data of three characters created by a single skilled voice actor/actress, the conversion can generate different kinds of character voices from an arbitrary speaker, while keeping the speaker identity. Listening tests were carried out by presenting two kinds of synthetic voices; before and after character conversion. The results showed that listeners, both native and non-native speakers, can perceive well the character voice difference between the two as what is intended by experimenters. It was also shown that this difference is perceived well even when F0 difference between the two was very small, which indicates better performance of our method in character conversion than that of the general F0-based conversion. Further, acoustic comparison between different characters in two cases of the voice actor and the proposed method was made. Results showed that the proposed method can realize acoustically valid modi cation between different characters. |
