| Abstract(in English) | This paper proposes techniques for flexibly controlling voice quality of converted speech from a particular source speaker based on one-to-many eigenvoice conversion (EVC). EVC realizes a voice quality control based on the manipulation of a small number of parameters, i.e., weights for eigenvectors, of an eigenvoice Gaussian mixture model (EV-GMM), which is trained with multiple parallel data sets consisting of a single source speaker and many pre-stored target speakers. However, it is difficult to control intuitively the desired voice quality with those parameters because each eigenvector does not usually represent a specific physical meaning. In order to cope with this problem, we propose regression approaches to the EVC-based voice quality control. The tractable voice quality control of the converted speech is achieved with a low-dimensional voice quality control vector capturing specific voice characteristics. Results of experimental evaluations show that the proposed approach allows us to intuitively control the voice quality of the converted speech. |
