Abstract
In this paper, we studied speech emotion recognition and proposed an improved speech emotion recognition method of the convolutional neural network. Improved methods are improving the algorithm of updating convolution kernel weight and transforming the data matrix of the Mel-Frequency Cepstral Coefficients (MFCC) obtained by preprocessing the speech signal. This makes that the algorithm of updating the convolution kernel weight during the training process of traditional convolutional neural networks was related to the number of iterations and increase the difference of emotional phonetic features. Therefore this improved the expressive ability of convolutional neural networks. Experiments showed that the error recognition rate of the improved speech emotion recognition method of the convolutional neural network was about 7% lower than that of the traditional method.
