| Outline of Final Research Achievements |
This research addresses measurement of personality and analysis of diversity in speech aiming at realizing speech synthesis with rich personalization.
I proposed a new method for measuring the difference of voice quality based on feature parameters of speech. The similarity of voice quality is calculated by weighted Euclidean distance of MFCC parameters which represent spectrum features of speech. I analyzed the relationship between prosodic information and personality perception using synthetic speech in which phonemic information is removed but prosodic information, such as intonation, is preserved. I also analyzed various types of speech which include dialect, character voices in ‘Anime’, announcer voices, emotional voices，and so on.
