Problems solved by technology

However, the inventors found the following problems in related technologies: when recognizing speech emotions, the number of input speech frames is not the same, so in order to meet the input length requirements, usually after the speech features are extracted, the features of different lengths Fill zeros to the same length, and then recognize the voice emotion, which will lose part of the content contained in the original voice, resulting in low accuracy for subsequent voice emotion recognition

Abstract

The invention relates to the field of voice recognition, in particular to a voice emotion recognition method and device and a storage medium. The voice emotion recognition method comprises the following steps: comparing the frame number of original voice with a preset voice frame number; if the frame number of the original voice is smaller than the preset voice frame number, copying frames of theoriginal voice and inserting the frames into the original voice to obtain standard voice conforming to the preset voice frame number; and according to the standard voice and a preset voice emotion recognition model, recognizing the emotion corresponding to the original voice. By adoption of the embodiment of the invention, the voice emotion can be recognized under the condition of keeping the voice characteristics of the original voice, so that the accuracy of a recognition result is guaranteed.

Description

technical field [0001] The invention relates to the field of voice recognition, in particular to a voice emotion recognition method, device and storage medium. Background technique [0002] With the rapid development of science and technology, automatic speech recognition services have gradually penetrated into all aspects of daily life. Usually, what people call automatic speech recognition mostly converts speech content into corresponding text content; but what people say includes not only text content, but also other important content such as volume, intonation, and speaking emotions. It has a great influence on the understanding of the text content. Sometimes the different emotions of the speech may lead to completely opposite meanings for the same sentence; therefore, recognizing the emotion corresponding to the speech is a relatively important part of the speech recognition service. Voice emotion recognition is usually based on a deep learning network. However, the i...
