Embodiment Construction

[0035] The technical solution in the embodiment of the present invention extracts short-term energy and its derivative parameters, pitch frequency and its derivative parameters, sound quality feature formant and its derivative parameters, and the 20th order obtained by MFCC from the preprocessed speech signal. The characteristic parameters including the Mel cepstral coefficients, the extracted characteristic parameters of the 20th-order Mel cepstral coefficients obtained by MFCC cover the whole frequency domain, compared with the MFCC parameters that only cover low frequencies, it can improve the frequency of medium and high frequencies. domain recognition accuracy, which can improve the accuracy of speech emotion recognition and improve user experience.

[0036] In order to make the above objects, features and beneficial effects of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the ...

Abstract

A voice emotion recognition method and device, a computer-readable storage medium, and a terminal, the method comprising: acquiring a voice signal to be processed; preprocessing the acquired voice signal to obtain a preprocessed voice signal; extracting the preprocessed The feature parameter of the speech signal after; Described feature parameter comprises short-time energy and derivative parameter thereof, pitch frequency and derivative parameter thereof, sound quality characteristic formant and derivative parameter thereof, the Mel cepstrum coefficient and the 20th order that MFCC asks for The maximum value of the first-order difference of the MFCC, the minimum value of the first-order difference of the MFCC, the mean value of the first-order difference of the MFCC and the variance of the first-order difference of the MFCC; use the extracted feature parameters to form a corresponding feature vector sequence to obtain the speech A feature vector sequence corresponding to the signal; using a support vector machine to train and identify the feature vector sequence corresponding to the speech signal, and obtain a corresponding speech emotion recognition result. The above solution can improve the accuracy of speech emotion recognition.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a speech emotion recognition method, a computer-readable storage medium, and a terminal. Background technique [0002] With the rapid development of information technology and the increasing dependence of human beings on computers, the ability of human-computer interaction has been paid more and more attention by researchers. In fact, the problems that need to be solved in human-computer interaction are consistent with the important factors in human-to-human communication, and the most critical is the ability of "emotional intelligence". [0003] At present, the research on emotional information processing is being deepened continuously, and the research on emotional information processing in speech signals has attracted more and more attention. Among them, speech emotion recognition refers to the technology of using signal processing technology and pattern recognitio...
