Abstract:

The change of human speech emotion is an abstract dynamic process, and it is difficult to describe its emotional interaction using static information. The rise of artificial intelligence has brought new opportunities for the development of speech emotion recognition. Starting from the concept of speech emotion recognition and the historical process of development at home and abroad, the research results of speech emotion recognition in recent years are summarized from five aspects. Firstly, the speech emotion characteristics are introduced, and the significance of various speech characteristic parameters on speech emotion recognition is summarized. Secondly, the classification and characteristics of speech emotion database, the classification and advantages and disadvantages of speech emotion recognition algorithms, the application of speech emotion recognition, and the challenges encountered in speech emotion recognition are described in detail. Finally, based on the current research situation, the future research and development of speech emotion recognition are prospected.
