| Outline of Final Research Achievements |
In order to convert pitch and quality of input speech and regenerate the converted speech, speech analysis-synthesis systems are widely used as a foundation technology. Although the state of the art of speech analysis-synthesis systems enables quite high-quality speech regeneration, it fails to regenerate high-quality speech for input speech which has peculiarity in vibration of vocal cords such as abnormal voice caused by laryngeal disease, shout singing voice, etc. In this research, we deal with such speech having peculiarity of vocal cords, and tackle it by improving a pitch-frequency extraction method and modeling the vibration of the vocal cords.
