Analysis and recognition of the functional expression of voice and face in agreement formation dialog

摘要

This paper describes an analysis and recognition of the head movement, and F0 pattern for human's agreement formation dialog. The half of a discourse coincided with a head movement as a result of analysis. In the pattern of a head nodding motion, correlation was seen between grade of the belief and the speed and strength of the motion. In the FO pattern, strong fluctuations of pitch were seen in the utterance of declaration and response. The recognition system which presumes the classification of a discourse was created using each feature, and the possibility of a pattern recognition system for the expression in dialog was examined.
