Abstract

A voice quality evaluation method includes: obtaining a time envelope of a voice signal (101); performing time-to-frequency conversion on the time envelope to obtain an envelope spectrum (102); performing feature extraction on the envelope spectrum to obtain a feature parameter (103); performing voice quality evaluation in voice communications according to the feature parameter to obtain a first voice quality parameter of the voice signal (104); calculating a second voice quality parameter of the voice signal by using a network parameter evaluation model (105); and performing a comprehensive analysis according to the first voice quality parameter and the second voice quality parameter to obtain a quality evaluation parameter of the voice signal that is input in the band (106). Also disclosed are a voice quality evaluation apparatus and a voice quality evaluation device.

Description

technical field [0001] The present invention relates to the field of audio technology, and in particular, to a method, device and equipment for evaluating voice quality. 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, the monitoring of the performance and quality of the voice communication network is becoming more and more 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. [0004] An existing objective evaluation technology of speech quality in the signal domain is to use a mathematical signal model to simulate the process according to the perception process of the human auditory system to the speech signal. The technology uses cochlear filters to imitate auditory perception, ...
