Abstract

The invention relates to the technical field of emotion recognition methods, in particular to an emotion recognition method and system based on nonlinear features. The method comprises a voice collection step: collecting voices of a user; a feature extraction step: processing and analyzing the voice of the user, and extracting the matched features which include audio features, nonlinear features,and semantic features; a model matching step: performing the matching of the matched features, extracted according to the feature extraction step, with a preset emotional models, and finding out the most matched emotion model as a result of emotion recognition. The emotion recognition method and system can comprehensively and accurately analyze and recognize user emotions from multiple angles andaspects according to the voice input.

Description

technical field [0001] The invention relates to the technical field of emotion recognition methods, in particular to an emotion recognition method and system based on nonlinear features. Background technique [0002] Emotion is a state that integrates people's feelings, thoughts, and behaviors. It includes people's psychological responses to external or self-stimuli, as well as the physiological responses that accompany such psychological responses. Human emotions are closely related to physical and mental health. If human beings are in a state of anxiety, sorrow, sadness, anger, and depression for a long time, it may lead to various diseases such as neurasthenia, high blood pressure, heart disease, ulcers, stomach problems, and cancer. Psychogenic diseases, so mastering the emotional state of a person, especially the elderly, is very beneficial to mastering the physical and mental state. [0003] Emotion recognition analysis is of great value to the elderly, especially the...
