| Outline of Final Research Achievements |
This project aimed to improve voice cconversion techniques which convert speech waveforms from original speaker's voice to another speaker's one. In conventional voice conversion technique, spectral features and prosodic features such as fundamental frequencies (F0) and speaking rates are indenedently converted. In the proposed technique, these features are consistently modeled using a single statistical model and all features are jointly converted using the correlation among features. Experimental results showed that the speech quality of converted voices was improved by the proposed technique. Moreover, the project also developed a technique to improve voice conversion with a very small amount of training data is available.
