| Outline of Final Research Achievements |
Speech consists of richer information than texts. They are non-linguistic information, such as individuality, emotional and physical states, and para-linguist information, which represents intention and/or expression using prosody. In cases of extreme voicing found in screaming, shout and artistic voice activities, conventional signal processing methods sometimes fail to handle unusual physical attributes found in such voices. New speech signal processing frameworks, which are capable of analyzing, modifying and synthesizing these speech sounds, were invented in this project. They are also implemented on tablets and used in various applications. The radically new formulation of voice morphing is a remarkable important achievement of this project, which provides unique and strong basis for investigating quantitative relations between physical attributes and psychological attributes in a mathematically sound manner. In addition, it emerged a prospective speech processing framework.
