Abstract

The invention provides voice emotion identification equipment and a voice emotion identification method. The voice emotion identification equipment comprises an emotion identification unit and a confidence judgment unit, wherein the emotion identification unit is used for identifying the current emotion state of voice of an addressor into a preliminary emotion state; and the confidence judgment unit is used for calculating the confidence of the preliminary emotion state and judging whether the preliminary emotion state is credible by using the confidence, and if so, the preliminary emotion state is determined as a final emotion state and the final emotion state is output. The confidence judgment is performed on the identification result of the voice emotion state and the final emotion state is determined according to the judgment result, so that the accuracy of the identification result of the voice emotion state can be improved.

Description

technical field [0001] The present invention relates to speech recognition technology, and more specifically, to a speech emotion recognition device and a speech emotion recognition method. Background technique [0002] Emotional ability is an important symbol of human intelligence. Emotion is essential in human interaction and plays an important role in human perception and decision-making. For a long time, the study of emotional intelligence existed only in the field of psychology and cognitive science. In recent years, with the development of artificial intelligence, the combination of emotional intelligence and computer technology has produced the research topic of emotional computing. This will greatly promote the development of computer technology. [0003] Speech is an important means of human communication and the most convenient, basic and direct way to transmit information to each other. Speech signals carry rich emotional information while conveying semantic in...
