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

Abstract

We propose a linear model of the relationship between the physical changes in speech and perceived emotional concepts. We make use of orthogonal bases in spite of the emotional words and the 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 or emotional concepts because the emotions that speakers intended rely on their personality and temporary psychological state. Evaluation for relative information indicates that the proposed linear model is representable for the relationship between the physical quantities and psychological quantities in speech.
