The first playback module 102 is connected to the first USB interface module 103, and the second playback module 105 is connected to the second USB interface module 106.

The first USB interface module 103 is configured to implement a USB connection with the first test terminal 12, and the second USB interface module 106 is configured to implement a USB connection with the second test terminal 13.

In this embodiment, the first test terminal 11 and the second test terminal 12 are both mobile phones, the mobile phones are provided with Type-C interfaces and do not have 3.5mm interfaces, the first test terminal is connected to the first USB interface module 103 through the Type-C interfaces of the first test terminal 11, and the second test terminal 12 is connected to the second USB interface module 106 through the Type-C interfaces of the second test terminal 12.
Voice quality assessment method embodiment:
the method for evaluating the voice quality according to the present embodiment is implemented based on the embodiment of the voice quality evaluation system, specifically, referring to fig. 1, the control module in the mos box implements the following steps by executing a computer program:
step S11 is first executed to determine a first test terminal and a second test terminal. The multiple test terminals can be connected with the MOS box in a Bluetooth connection and USB connection mode, the first test terminal and the second test terminal are used for description, the first test terminal and the second test terminal are selected to complete the voice quality assessment method of the embodiment, the first test terminal is firstly used as a sound playing terminal, and the second test terminal is used as a sound recording terminal.
Then, step S12 is performed to obtain the audio standard file from the first test terminal through the bluetooth communication mode. The first test terminal and the second test terminal are respectively pre-stored with a plurality of different audio standard files, at the moment, a tester can select the audio standard files for voice quality evaluation at the first test terminal, the first test terminal sends the selected audio standard files to the MOS box in a Bluetooth communication mode, and the MOS box acquires the audio standard files from the first test terminal in a Bluetooth communication mode.
When the audio standard file is an audio file in a WAV format and is stored on the first test terminal and the second test terminal, the WAV file generally occupies a larger capacity, and can be compressed through a preset format, for example, the WAV file is compressed according to a ZIP format to obtain a compressed audio standard file, and the compressed audio standard file is transmitted through Bluetooth communication, so that the low bandwidth instantaneity and stability are ensured, the transmission efficiency is improved, and the storage space occupied by the first test terminal and the second test terminal is reduced. In addition, verification information can be set for the compressed audio standard file, when the MOS box receives the compressed audio standard file, the integrity of the file can be detected through the verification information, the compressed audio standard file can be encrypted, and the transmission safety is guaranteed.
Then, step S13 is executed to determine audio test flow parameters according to the audio standard file. The audio test flow parameters comprise audio test start time, audio test end time, serial numbers and times.
Therefore, the number of times of playing operation needed by the first test terminal when the first test terminal is used as a playing terminal can be determined according to the number of times, the number of times of recording operation needed by the first test terminal when the first test terminal is used as a recording terminal is determined, the number of times of playing operation needed by the second test terminal when the second test terminal is used as a playing terminal is determined, the number of times of recording operation needed by the first test terminal is equal to the number of times of playing operation needed by the second test terminal, and the number of times of playing operation needed by the first test terminal is equal to the number of times of recording operation needed by the second test terminal. According to the serial number, whether the first test terminal performs the recording operation or the playing operation first can be determined, in this embodiment, the first test terminal performs the playing operation first, and correspondingly, the second test terminal performs the recording operation first. The audio test starting time defines the starting time of the first test terminal executing the playing operation and the second test terminal executing the recording operation in each test, and the audio test ending time defines the ending time of the second test terminal executing the playing operation and the first test terminal executing the recording operation in each test.
In addition, the audio test flow parameters also comprise sampling rate, buffer area size, channel number and bit depth. The sampling rate determines the accuracy of the audio, the higher the sampling rate, the higher the accuracy of the audio. The buffer size, which is the size of the area where the audio is transmitted and stored, determines the time interval and delay between each sample point, and the smaller the buffer, the less the time interval between each sample point, but the higher the delay will be, the longer the time interval between each sample point, the more data will be processed, and the shorter the delay will be. The number of channels determines the number of independent audio channels provided in the audio, typically configured as mono or stereo channels, and the increase in channels may be more stereo and realistic in the audio output, but may also result in greater data throughput and transmission costs. The bit depth determines the dynamic range and accuracy of the audio signal, and higher bit depths may provide higher sound quality and accuracy. The setting of the number of channels and the bit depth may be set by an audio codec. The amount of data in the audio stream will vary accordingly depending on the setting, which will affect the buffer size and delay of the audio processing. By setting the proper sampling frequency, the number of channels and the bit depth, the quality and the precision of the audio signal can be ensured to the greatest extent, and the delay of the buffer zone can be reduced as much as possible, thereby improving the performance and the efficiency of the audio system. Therefore, the buffer zone size suitable for the recording operation and the playing operation can be set according to the audio standard file, the buffer zone size is related to the audio sampling rate and the playing times, and the corresponding aspects of the number of channels, bit depth and the like are set for the audio with different sampling frequencies so as to reduce the delay of the buffer zone and improve the accuracy of audio sampling.
And then executing step S14, and respectively transmitting the audio test flow parameters to the first test terminal and the second test terminal in a Bluetooth communication mode. Therefore, the synchronous operation of each round of recording and playing process in the same time range can be ensured, and the correctness and reliability of the test are ensured.
Then, step S15 is executed to play the audio standard file through the first playback module. The MOS box outputs the audio signal of the audio standard file through the first playback module and the first USB interface module.
After executing step S15, referring to fig. 4, at this time, the first test terminal continues to implement the voice quality assessment method of the present embodiment by executing the corresponding computer program, and referring to fig. 5, at this time, the second test terminal continues to implement the voice quality assessment method of the present embodiment by executing the corresponding computer program. Fig. 4 specifically includes:
and S21, starting voice communication with the second test terminal according to the audio flow parameters. The voice communication may be a network having high-definition transmission characteristics such as a 5G voice (VoNR) or a 4G voice (VoLTE) network, so that high-quality audio can be evaluated.
Step S22, the audio signal of the audio standard file is obtained from the MOS box through the first USB interface module.
And step S23, the audio signal is sent to the second test terminal through voice communication.
Fig. 5 specifically includes:
step S31, voice communication with the first test terminal is started according to the audio flow parameters.
Step S32, recording real-time network signaling data.
Step S33, obtaining the audio signal of the audio standard file from the first test terminal through voice communication, recording the audio signal and generating an audio degradation file.
And step S34, MOS test is carried out according to the audio standard file, the audio degradation file and the real-time network signaling data, and the voice quality evaluation score is determined. I.e. the speech quality assessment score is determined by the scoring criteria of the existing MOS test.
Thus, voice quality assessment is achieved through cooperation among the MOS box, the first test terminal and the second test terminal.
In addition, on this basis, the control module of the MOS box also needs to continue to execute S16, and play the audio standard file through the second playback module. At this time, the first test terminal is used as a recording terminal, and the second test terminal is used as a playback terminal, so that the second test terminal is directly changed into the playback terminal, and the first test terminal is changed into the recording terminal for testing. Referring to fig. 6, the steps to be executed when the second test terminal is used as a playback terminal are similar to the steps to be executed when the first test terminal is used as a playback terminal, referring to fig. 7, the steps to be executed when the first test terminal is used as a recording terminal are similar to the steps to be executed when the second test terminal is used as a recording terminal, and are not repeated herein.
In summary, the audio standard file and the audio flow test parameters are transmitted in a Bluetooth communication mode, and the audio signal of the audio standard file is directly transmitted through the first USB interface module, so that the audio quality evaluation can be realized without requiring a 3.5mm earphone hole on the mobile phone, and the reliable test is ensured through the audio flow test parameters. In addition, as the first test terminal and the second test terminal only need to start corresponding recording or playing functions according to the audio test flow parameters sent by the MOS box, audio signals can be directly obtained through the USB interface module on the MOS box, the requirements on the adopted test terminals are reduced, special processing such as brushing of special firmware or opening of a system bottom layer is not needed, and the implementation is convenient.
