Problems solved by technology
[0015] However, judging from the many articles, patents and patent applications published at present, most speech emotion recognition schemes focus on recognizing the emotional state of speech by means of speech features and emotional state models, without taking into account speech features and The influence of factors such as the emotional state model on the accuracy of the recognition results, and the accuracy of the recognition results cannot be dynamically adjusted, thus resulting in an unstable recognition result accuracy that needs to be improved

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-human interaction and plays an important role in human perception and decision-making processes. For a long time, emotional intelligence research only exists in the fields 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] Voice is an important means of human communication, and it is the most convenient, basic and direct way to transfer information to each other. While the speech signal conveys semantic information, it also ca...
