example 1

[0123] The audio call evaluation method provided in this example includes three stages: corpus preparation, test execution, and quality evaluation.

[0124] Corpus preparation (comprising audio and the corresponding text of audio) may comprise the following steps:

[0125] Step p1. Select a speech recognition program that can convert speech output into text output. A speech recognition program can be used for speech recognition.

[0126] Step p2. Prepare a piece of reference audio (referred to as reference audio) and corresponding text (referred to as reference text). The reference audio may be but not limited to a piece of news broadcast. The reference audio can include: different versions of audio, for example, male voice version audio, female voice version audio, children's voice version audio, official language version audio, and dialect version audio. The normal playback speed of the reference audio can last for The predetermined duration is, for example, about 2 minut...

example 2

[0155] Figure 5 It is a complete audio call evaluation system, which consists of two parts: the reference audio sending end, the reference audio receiving end and the evaluation end. The transmitting end of the reference audio transmits the prepared reference signal of the reference audio to the device under test. The acquisition module collects the damaged audio data received by the device under test through the acquisition interface; the recognition module recognizes the voice data, converts the voice data into recognition text, and the evaluation module uses the recognition text output by the recognition module and the reference audio The relative reference text is used as input, and the MSS score is calculated.

[0156] Taking the test of the handheld mobile station as an example, a voice call is first established between two mobile stations (1 and 2). The reference signal sending end transmits the reference audio signal to the mobile station 1 under test; the evaluatio...

Abstract

The embodiment of the invention discloses an audio call assessment method, assessment equipment and a computer storage medium. The audio call assessment method is applied to the assessment equipment,and comprises the following steps: a recognition text of received audio is obtained, wherein the recognition text is a recognition result of the received audio after transmission of reference audio attransmit-receive dual ends; and by combining the recognition text and a reference text corresponding to the reference audio, an effect assessment value of the audio call is obtained.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to an audio call evaluation method, evaluation equipment and a computer storage medium. Background technique [0002] The call quality evaluation of the current audio call is performed by human beings. On the one hand, this kind of people-involved evaluation requires people to participate, consumes a lot of manpower, and is inefficient; Different evaluation values ​​are obtained, which introduces human errors, resulting in evaluation results that cannot objectively reflect the real call effect. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide an audio call evaluation method, evaluation device, and computer storage medium, which at least partially solve the above problems. [0004] In order to achieve the above object, technical solution of the present invention is achieved in that way: [0005] In the first aspect...
