We used deep learning to estimate emotional intensity from speech. In our previous study, we considered emotional intensity as 10 categories and estimated emotional intensity by categorization, but the flexibility of this method was insufficient. To solve this problem, in this study, we calculated the perceived intensity values using two evaluation methods by means of an emotional perception evaluation experiment of speech. As a result, we confirmed the nonlinearity of the intensity values of each emotional intensity category in the emotional perception evaluation experiment. As a result, the estimated intensity values with an average correlation coefficient of 0.73 with the set intensity values of speech were obtained in the emotional intensity estimation model using perceived intensity values. |
