Emotion recognizing method, sensibility creating method, device, and software
First Claim
1. An emotion detecting method for detecting an emotion of a subject, comprising the steps of:
- inputting a voice signal;
detecting an intensity of a voice and a tempo expressing speed the voice emerges at, respectively, and detecting, as a time value, intonation expressing an intensity-change pattern in each word the voice makes, based on the inputted voice signal;
obtaining a first amount of change indicating a change in the intensity of the detected voice, in a direction of time axis, a second amount of change indicating a change in the tempo of the voice, in the direction of time axis, and a third amount of change indicating a change in the intonation in the voice, in the direction of time axis, respectively; and
generating signals expressing states of emotion of at least anger, sadness, and pleasure, respectively, based on said first, second, and third amounts of change.

Abstract
An object of the invention is to provide an emotion detecting method capable of detecting emotion of a human accurately, and provide sensibility generating method capable of outputting sensibility akin to that of a human. An intensity, a tempo, and intonation in each word of a voice are detected based on an inputted voice signal, amounts of change are obtained for the detected contents, respectively, and signals expressing each states of emotion of anger, sadness, and pleasure are generated based on the amounts of change. A partner'"'"'s emotion or situation information is inputted, and thus instinctive motivation information is generated. Moreover, emotion information including basic emotion parameters of pleasure, anger, and sadness is generated, which is controlled based on the individuality information.
