Problems solved by technology

At present, most of the emotion recognition on the market is text-related. For example, the emotion recognition of Huawei, HKUST Xunfei, and Baidu are all based on text, while the text-independent speech emotion recognition scheme is still in the research stage, and has not yet been proposed. A solution that is effective and can guarantee a high recognition rate

Abstract

The invention discloses a text-independent speech emotion recognition method. The method comprises the following steps: acquiring real-time audio data, recognizing the real-time audio data through a trained algorithm model for speech emotion recognition, and determining the emotion state of a speaker, being implemented by performing endpoint detection on the acquired real-time audio data by usinga phoneme alignment processing mode; performing feature value extraction on the real-time audio data after end point detection; and inputting the extracted feature values into an algorithm model, anddetermining the emotional state of the speaker according to the emotional state prediction probability output by the algorithm model. The invention also discloses a text-independent speech emotion recognition device and a model training method. By adopting the scheme disclosed by the invention, the recognition accuracy can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of intelligent speech, in particular to a text-independent speech emotion recognition method and device and a method for generating an algorithm model for emotion recognition. Background technique [0002] In recent years, with the development of intelligent speech technology, emotion-based speech recognition has gradually become a new research direction and hot spot. At present, most of the emotion recognition on the market is text-related. For example, the emotion recognition of Huawei, HKUST Xunfei, and Baidu are all based on text, while the text-independent speech emotion recognition scheme is still in the research stage, and has not yet been proposed. It is an effective solution that can guarantee a higher recognition rate. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the existing solutions, the inventors have made a lot of attempts and research in algor...
