Problems solved by technology

[0005] In view of this, the present invention provides a method, a device and a system for testing the quality of a voice call. The method can simultaneously communicate with two groups of input tests, and solve the problem of low test efficiency and multiple groups of voices in the existing voice quality test method. When repeating the test, the reliability of the test result is poor, etc.

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] First, see attached figure 1 , the embodiment of the present invention discloses a method for testing voice call quality, the method comprising:

[0043] S1: establish network calls in two groups of network terminals respectively;

[0044] S2: Play the sample audio signal, respectively input the left channel audio signal in the played audio signal to the first group of network terminals, and input the right channel audio signal in the played audio sign...

Abstract

The invention discloses a voice call quality test method, device and system. According to the scheme, the two network terminals can be simultaneously connected through a two-in one-out audio cable anda one-in two-out audio cable; therefore, two calls are simultaneously tested at the same input; thus, when the network resistance of two voice software or one voice software of different versions needs to be tested, repeated tests for two times are not needed, the two tests can be carried out at the same time; even if network damage occurs, due to the fact that the two tests use the same networkcondition and are consistent in input, the output comparison can more accurately reflect the advantages and disadvantages of network resistance of the two groups tests , the test efficiency is improved, and more importantly, comparison is more accurate, and the comparison result is more reliable and credible.

Description

technical field [0001] The present invention relates to the technical field of communication and speech quality detection, and more specifically relates to a method, device and system for testing the quality of a speech call. Background technique [0002] At present, with the development of mobile network standards, people have higher and higher demands on the quality of voice calls. Therefore, how to effectively and comprehensively test the call quality is a very important issue. In the prior art, the sound quality damage is evaluated by injecting a test sample, and then looking at the difference between the output sound of the receiving end and the test sample, and then evaluates the call quality. [0003] However, this method can only complete one set of tests at a time. If you need to test the quality of multiple voice calls, you need to repeat the test. The test efficiency is low, and during the test process, the comparison error caused by network uncertainty is large. ...
