Abstract

The invention provides an unspecific human voice and emotion recognition method and system, wherein the method comprises the steps of extracting phonetic features used for recognizing the emotional paralanguage from the voice signal to be recognized, extracting acoustic voice emotional characteristics of the emotional voice signal to be recognized, and mixing recognition results of an emotion recognition channel based on emotional paralanguage and an emotion recognition channel based on acoustic voice emotional characteristics to obtain the emotional state contained in the emotional voice signal to be recognized. By utilizing the characteristics that the change of speakers has little influence on the emotional paralanguage, the emotional paralanguage reflecting the emotion information can be extracted from the emotional voice signal, and the emotion information contained in the emotional paralanguage can assist the auxiliary acoustic emotional characteristics for emotion recognition, so that the purposes of improving the robustness and recognition rate of the voice and emotion recognition can be achieved.

Description

technical field [0001] The present invention relates to the technical field of voice recognition, in particular to a method and system for voice emotion recognition of a non-specific person. Background technique [0002] The development of speech emotion recognition technology plays an important role in promoting the development and application of intelligent and humanized new human-computer interaction technology. How to use computer technology to automatically recognize the speaker's emotional state from speech has been researched by researchers in various fields in recent years. extensive attention. Existing speech emotion recognition research still has many limitations, especially the distribution of speech emotion feature parameters in the emotion space will change with the change of the speaker, and the accuracy of emotion recognition is greatly affected by the change of the speaker. As a result, when the speaker of the speech to be recognized is not in the training l...
