| Outline of Final Research Achievements |
In this research project, we improved and advanced techniques of recognition and synthesis of various speech, and studied a state estimation technique of system users and its applications to realize a dialogue system kind to users. Specifically, (1) We studied the validity of using emotions and a technique for emotion estimation. (2) We proposed and evaluated a sentence selection technique based on extended entropy where phonetic and prosodic contexts are taken into account. (3) We recorded and analyzed dialogue data for willingness estimation. (4) We constructed a large-scale emotional speech corpus that can be used for emotional speech synthesis/recognition and emotion estimation. (5) We proposed and evaluated variance compensation and taylor-made speech synthesis as a technique of synthesizing various and high-quality speech synthesis.
