Method, device and equipment for evaluating speech quality

Abstract

The embodiment of the invention discloses a method, a device and equipment for evaluating speech quality, so as to lessen problems of high complexity and serious resource consumption of the existing signal domain evaluation scheme. The method of the embodiment of the invention comprises steps: the time domain envelope for speech signals is acquired; time-frequency transform is carried out on the time domain envelope to acquire an envelope spectrum; feature extraction is carried out on the envelope spectrum to acquire feature parameters; and according to the feature parameters, communication speech quality evaluation is carried out to acquire first speech quality parameters of the speech signals, and according to the first speech quality parameters and second speech quality parameters, comprehensive analysis is carried out to obtain the quality evaluation parameters of the section of inputted speech signals. The embodiment of the invention evaluates the quality of the speech signals in a condition of simulating auditory perception not based on a high-complexity cochlear filter, the calculation complexity is reduced, and the resource consumption is reduced.

Description

technical field [0001] The present invention relates to the field of audio technology, in particular to a voice quality assessment method, device and equipment. Background technique [0002] In recent years, with the rapid development of communication networks, network voice communication has become an important aspect of social communication. In the current big data environment, monitoring the performance and quality of voice communication networks is doubly important. [0003] At present, there is no simple and effective low-complexity algorithm for the objective evaluation model of communication voice quality in the signal domain. The industry still focuses on researching a large number of factors that affect communication voice quality, and few studies can give a low-complexity signal domain evaluation model. [0004] An existing objective assessment technology of speech quality in the signal domain is to use a mathematical signal model to simulate the process of speech...
