Speech emotion detection method and device, computer equipment and storage medium

Abstract

The invention provides a speech emotion detection method. The speech emotion detection method comprises the steps of obtaining speech data to be detected; performing framing on the speech data to be detected to obtain speech frames, extracting speech features of each speed frame to form a speech feature matrix, inputting the speech feature matrix into a trained emotion state probability detectionmodel, outputting an emotion state probability matrix corresponding to the speech date to be detected, inputting the emotion state probability matrix and the voice feature matrix into a trained emotion state transition model to obtain a corresponding emotion state sequence, wherein the trained emotion state transition model comprises a trained emotion state transition probability parameter, and determining the emotion state corresponding to the speech data to be detected according to the emotion state sequence. The method provided by the invention greatly improves the accuracy of speech emotion detection. In addition, the invention further provides a speech emotion detection device, computer equipment and a storage medium.

Description

technical field [0001] The invention relates to the field of computer processing, in particular to a voice emotion detection method, device, computer equipment and storage medium. Background technique [0002] With the development of speech recognition technology, the technology of converting speech into text has been relatively mature, but the traditional speech-to-text technology can only recognize the user's basic speech in terms of speech input, and cannot well recognize the user's emotion when speaking. [0003] The traditional voice emotion recognition method is to determine the emotional information contained in the voice information by analyzing the relevant parameters of the voice information, such as audio, pitch, etc., because the parameters collected in the above method are relatively one-sided, and cannot accurately reflect the information contained in the voice information. emotional information, so the accuracy of recognizing speech emotion in traditional meth...
