Abstract: A voice quality evaluation method includes obtaining a time envelope of a voice signal. The method includes performing time-to-frequency conversion on the time envelope to obtain an envelope spectrum. The method includes performing feature extraction on the envelope spectrum to obtain a feature parameter. The method includes performing voice quality evaluation in voice communications according to the feature parameter to obtain a first voice quality parameter of the voice signal. The method includes calculating a second voice quality parameter of the voice signal by using a network parameter evaluation model. The method includes 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.
