| Abstract(in English) | This paper proposes method for recognizing emotion in speech with the nonlinear operator of the Teager Energy Operator (TEO). Because we think that emotion is a kind of stress, we apply the TEO, which is used for the stress detection, to emotion recognition. We propose the four features calculated by the TEO, i.e. TEO-CB-Auto-Env, TEO-Auto-Env, TEO-FM-Var, TEO-LFPC. In experiments, we compared recognition performances by each of four TEO-based features and the conventional features of pitch and MFCC. We also investigated recognition rate by integrating the four TEO based features and MFCC. We used four kinds of speeches, 62 neutral, 43 joyful, 61 angry, and 51 sad speeches. As a result, we have obtained the average recognition rate of 51%, and maximum rate of 61% in sad emotion. The proposed method, however, misjudge "sadness" for "neutral". |
