Measurement of human vocal emotion using fuzzy control

This paper proposes a sentiment measurement system that is based on the relation between speech parameters and included emotion and that is implemented through a learning process using speech data which include known sentiments. In this study, “emotion” and “sentiment” are distinguished in a model of emotional communication by speech which for the first time includes the viewpoint of the observer in addition to those of the speaker and the listener. The sentiment measurement system is constructed by implementing a computational model of the observer. A fuzzy control method is applied in the learning process. The effectiveness of the system is verified by experiments in which the system outputs are compared with psychological evaluations by human subjects. © 2001 Scripta Technica, Syst Comp Jpn, 32(4): 59–68, 2001
