Outline of Final Research Achievements

The purpose of the research is to develop advanced techniques that enable us to model acoustic features of prosodic information as well as spectral information with being less dependent on quality and quantity of training speech data for synthesizing natural-sounding and diverse expressive speech. We have proposed several robust techniques such as style control and prosody modeling ones and showed their effectiveness through objective and subjective evaluation tests. We have also applied the proposed techniques to under-resourced languages. Furthermore, we examined a cross-lingual speech synthesis technique for universal speech communication.
