E-4-3 Trial of Speech Assessment by an Applied Fuzzy Inference

Abstract

We analyzed the relation between the fuzzy ratings obtained from an applied fuzzy inference on the physiology (blood pressure and heart rate) and the psychological index (anxiety) at the time before a presenter making a speech, by setting the time of making a speech as a tension scene, and the self-and others- evaluations on the speech. As a result, the presenters whose fuzzy ratings (G) were higher than those who were lower showed a markedly higher tendency in both self-and others- assessment. From this finding, it is suggested that the fuzzy ratings (G) on blood pressure and anxiety before making a speech may give an effective clue in understanding the relation between the condition immediately before making a speech and the performance.
