Evaluation of the relationship between emotional concepts and emotional parameters on speech

In this paper, we propose the linear model of the relationship between the physical changes in speech and perceived emotionaI concepts. We make use of orthogonal bases in spite of emotional words and physical parameters themselves in order to avoid dependence on the method of selecting words and parameters. Furthermore we regard the emotions that listeners perceive from speech as the standard of emotional concepts because the emotions that speakers intended rely on personality and temporary psychological state. Evaluation for relative information indicates that the proposed linear model is representable for the relationship between physical quantities and psychological quantities in speech.
