Abstract

The invention relates to a sound quality evaluation method and device, electronic equipment and a storage medium. The sound quality evaluation method comprises the following steps of acquiring the sound quality evaluation information about an audio signal sent by a sending end, the network transmission information and an audio signal received by a receiving end; and obtaining a tone quality evaluation result about voice communication between the sending end and the receiving end according to the obtained tone quality evaluation information, the network transmission information and the audio signal received by the receiving end.

Description

Technical field [0001] The present disclosure relates to the field of signal processing, and more particularly to a sound quality assessment method, apparatus, electronic device, and storage medium, and also relates to a training method and training device for a deep neural network model for sound quality assessment. Background technique [0002] The objective quality assessment of audio signals can be divided into two methods, namely, complete reference methods and non-reference methods. Such as PESQ and POLQA are a fully reference speech quality assessment method. The input signal required by the fully referred to the method is the original non-destructive speech signal and the sound quality, which is reduced by various possible reasons (signals that will be evaluated). By comparing the original reference signal and the corresponding evaluation signal, a gap value is obtained, and the mass of the scaled signal is given according to the size of the gap (eg, score). Compared to t...
