Abstract

The invention discloses an objective voice communication quality evaluation method based on PESQ. It specifically includes the following steps: mobile phone A and mobile phone B establish a VOIP call through the voice communication system to be tested; the software system on the PC end starts, and the test audio is played on the PC end; the test audio is transferred from the speaker on the PC end through the audio cable and audio The call software in mobile phone B collects the test audio and transmits it to mobile phone A through the network; mobile phone A is connected to the PC terminal through the audio cable, and the test audio is transmitted from mobile phone A to the PC terminal through the audio cable. Perform audio recording and collection on the terminal; use the original test audio file and the recorded audio file as input for PESQ algorithm evaluation, and output the MOS quality score. The beneficial effects of the present invention are: it can quickly and effectively distinguish the quality of voice communication between systems, it can not only avoid a large amount of manpower input in traditional MOS sub-test, but also quickly generate evaluation results.

Description

technical field [0001] The invention relates to the technical field of voice communication, in particular to an objective voice communication quality evaluation method based on PESQ. Background technique [0002] In a traditional measurement of audio perception, a group of people is gathered and asked to judge the sound quality of various audio clips, and each person is assigned a score, usually on a scale of 1 to 5. When all individual scores are counted, the averaged result is called the Mean Opinion Score (MOS). This method is very labor-intensive and the test cycle is relatively long. Contents of the invention [0003] The present invention aims to overcome the above-mentioned deficiencies in the prior art, and provides a labor-saving and fast PESQ-based objective voice communication quality evaluation method. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A method for evaluating the quality of...
