Non-reference audio quality evaluation method and system based on audio signal property classification

The invention provides a non-reference audio quality evaluation method and system based on audio signal property classification. The method comprises the following steps: 1, establishing a training model based on a reference audio quality evaluation model, and adopting machine learning to acquire the relation between the audio quality of audio signals of different types and a network parameter, namely a non-reference audio quality evaluation model; 2, in network transmission of the audio signal network, inputting the current packet loss rate, the current delay time and the audio signal type of current packet loss data into the non-reference audio quality evaluation model, and acquiring the current audio quality. According to the non-reference audio quality evaluation method and system based on audio signal property classification, quality evaluation is conducted on signals of different types through different quality evaluation relations, user experience can be reflected more truly.
