Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0020] Such as figure 1 Shown is a structural block diagram of a speech emotion recognition system of the present invention. The invention provides a speech emotion recognition system, which is characterized in that it includes a speech preprocessing module, an emotional feature extraction module, and a sentiment analysis module. The input terminal of the speech preprocessing module is connected to speech data, and the output of the speech preprocessing module is terminal is connected with the input end of the emotional feature extraction module, the output end of the emotional feature extraction module is connected with the input end of the emotional analysis module, and the output end of the ...

Abstract

The invention discloses a speech emotion recognition system, including a speech preprocessing module, an emotional feature extraction module, and an affective analysis module. The input end of the speech preprocessing module is connected with the speech data, the output end of the speech preprocessing module is connected with the input end of the emotion feature extraction module, the output end of the emotion feature extraction module is connected with the input end of the emotion analysis module, and the output end of the emotion analysis module outputs an analysis recognition result. The speech pre-processing module obtains the speech signal through processing the speech data, and transmits the speech signal to the emotion feature extraction module to extract the acoustic parameters closely related to the emotion in the speech signal, and finally sends the acoustic parameters to the emotion analysis module to complete the emotion judgment. The invention also provides a speech emotion recognition method, which adds a detection means of a telephone fraud system, and can carry out multi-dimensional analysis on the speech data, and the detection accuracy rate of the system is improved by 5%.

Description

technical field [0001] The invention relates to a voice emotion recognition system and a recognition method, belonging to the technical field of voice analysis. Background technique [0002] At present, the existing telephone fraud prevention and interception systems are mainly the early warning and prevention technology based on signaling data, the fraud call early warning technology based on harmful recording comparison, and the natural person fraud call early warning technology based on intelligent voice technology. These technical routes exist. For the following problems, simple signaling analysis and recording comparison analysis do not provide much feature information, and it is difficult to give consideration to all parties in terms of accuracy and comprehensiveness. In addition, for voice topic analysis, it is necessary to accumulate voices for a period of time, which requires relatively high system voice access capabilities and processing and analysis capabilities, ...
