Emotion recognition of speech is the basis of human-computer interaction interface, and has also made remarkable development in the past decade. This paper summarizes the preprocessing and feature extraction methods and different existing emotion models and database. The speech is collected and converted into signals, and then the extracted features are identified through the speech recognition model. It also explains the still existing shortcomings at the present stage, such as emotional complexity and high-quality emotional corpus is difficult to obtain. In addition, this paper also introduces the future development and optimization direction of speech emotion recognition. It’s important for researchers to accurately describe the association between emotion and acoustic characteristics, and construct a recognition model that is reasonable and as close to the emotion processing mechanism of human brain.
