Detailed Description
In the embodiment of the invention, both the calling device and the called device are tested devices in a voice test process, wherein the tested devices have the functions of voice communication, voice data playing and voice data recording, such as a mobile phone or a tablet personal computer.
In a specific embodiment, the tested devices are all installed with an application for voice testing, and a tester can perform voice testing through the application. The application may provide a test setup interface that allows a tester to configure the device under test as either a calling device or a called device through the setup interface. The application can also provide a test interface, and allows a tester to click a test function key in the interface to start a voice test process, so that one-key voice test is realized. For example, if the device to be tested is configured as a called device, after the test function key is clicked, the called device starts a voice test process, acquires a time difference between the calling device and the called device through bluetooth connection with the calling device, instructs the calling device and the called device to establish a session, determines a playing time of audio data according to the acquired time difference and the current time of the called device, and plays audio test data to the calling device through the session; at this time, the tested device configured as the corresponding calling device sends a call request to the called device according to the indication of the called device, establishes a session with the called device, records audio data played by the called device and received through the session, and sends the recorded audio data to the voice test device. If the device to be tested is configured as a called device, after the test function key is clicked, the called device starts a voice test process, acquires a time difference between the calling device and the called device through bluetooth connection with the calling device, instructs the calling device and the called device to establish a session, determines a recording time of audio data according to the acquired time difference and the current time of the called device, records audio test data played by the calling device through the session, and sends the recorded audio data to the voice test device; and at the moment, the tested equipment configured as the corresponding calling equipment sends a calling request to the called equipment according to the indication of the called equipment, establishes a session with the called equipment and plays audio test data to the called equipment through the session.
At a certain moment in the voice testing process, if the calling device plays the audio test data through the session between the calling device and the called device, the called device can only record the audio data received through the session at the moment, and if the calling device records the audio data received through the session between the calling device and the called device, the called device can only play the audio test data through the session at the moment, so that the playing source of the voice test data in the voice testing process is unique, and the reliability of the voice test result is improved.
Fig. 1 exemplarily shows a flow of a voice testing method provided by an embodiment of the present invention, in which a called device refers to a device under test configured as a called device, and a calling device refers to a device under test configured as a calling device. As shown in the figure, the process mainly comprises the following steps:
step 101: and the called device acquires the time difference between the calling device and the called device through the Bluetooth connection between the called device and the calling device according to the voice test request.
In specific implementation, a tester can submit a voice test request through a test interface provided by an application for voice test installed in the called device. For example, the tester may submit the voice test request by clicking a button named "start test" provided in the interface to trigger the called device and the calling device to start the voice test, or, for example, the tester may submit the voice test request by clicking a button named "synchronize" provided in the interface to trigger the time synchronization process between the calling device and the called device. During the period, if the Bluetooth connection is established between the calling device and the called device, the time difference between the calling device and the called device is obtained through the Bluetooth connection between the calling device and the called device, if the Bluetooth connection is not established between the calling device and the called device, the called device starts a Bluetooth mode, nearby devices which start the Bluetooth mode are scanned, after the calling device is found, the Bluetooth connection is established between the called device and the calling device, and the time difference between the calling device and the called device is obtained through the Bluetooth connection.
Step 102: the calling device sends a call request to the called device to establish a session with the called device.
Specifically, the calling device sends a call request to the called device according to the indication of the called device, and establishes a session with the called device. For example, after acquiring the time difference between the calling device and the called device, the called device instructs, through bluetooth connection with the calling device, the calling device to send a call request to the called device according to the instruction of the called device, and establishes a session with the called device.
Step 103: and the called device determines the playing time of the audio test data according to the time difference and the current time of the called device, and plays the audio test data to the calling device through the conversation. Optionally, the duration of the session is longer than the playing duration of the audio test data.
The voice test data is built in the called device or provided by other devices connected with the called device. Specifically, if the voice test data is provided by another device connected to the called device, at this time, a Microphone (MIC) of the called device is connected to the other device, so that the called device plays the voice test data to the calling device through the other device.
Step 104: the calling device records the audio data received through the session and sends the recorded audio data to the voice test device.
Specifically, the time t3 at which the calling device records the audio data received through the session is the current time of the clock of the calling device.
Step 105: the voice test equipment determines the quality of the conversation according to the received audio data and the audio test data.
Specifically, the voice testing device processes the received audio data and the audio testing data by using a subjective Quality Evaluation of Speech Quality (PESQ) algorithm to obtain a Mean Opinion Score (MOS) of the session, and determines the Quality of the session according to the obtained MOS.
In step 101, the called device obtains a time difference between the calling device and the called device by the following steps: the called device sends a synchronization request to the calling device through the Bluetooth connection between the called device and the calling device, and determines the time difference between the called device and the calling device according to the current time of the clock of the calling device and the current time of the clock of the called device carried in the response message returned by the calling device, wherein the synchronization request is used for acquiring the current time of the clock of the calling device. Specifically, the called device sends a synchronization request to the calling device through a bluetooth connection with the calling device, the calling device carries the current Time of a clock of the calling device in a response message, and returns the response message to the called device, and the called device takes a difference value between the Time of the clock when the called device receives the response message and the Time of the clock of the calling device carried in the response message as a Time difference between the calling device and the called device, wherein the called device sends the synchronization request to the calling device by using a Network Time Protocol (NTP). At this time, the called device is an NTP Client (NTP Client), and the calling device is an NTP Server (NTP Server). After the called device obtains the time difference between the calling device and the calling device, the clock of the called device can be set according to the time difference, so that the time of the called device and the time of the calling device are synchronized.
Optionally, if the time difference obtained by the called device is greater than a first threshold, the called device obtains the time difference between the calling device and the called device through bluetooth connection with the calling device again, where the first threshold is determined according to experience or simulation results. When the time difference acquired by the called device is larger than the first threshold value, the called device determines that the time of the calling device is asynchronous with the time of the called device, and sends a synchronization request to the calling device through Bluetooth connection with the calling device again to perform time synchronization again without stopping voice testing or operating by a tester. Specifically, when the called device performs a voice test, a synchronization request is sent to the calling device at intervals of a set duration through bluetooth connection with the calling device to monitor whether the called device and the calling device are synchronized, and when the called device and the calling device are not synchronized, a synchronization state is recovered in time.
Because the called device is connected with the calling device through the Bluetooth, the time difference between the calling device and the called device is obtained, and the time synchronization between the calling device and the called device is realized, so the time synchronization precision between the calling device and the called device is influenced by the size of the Bluetooth transmission delay. In order to ensure the accuracy of time synchronization between the called device and the calling device, the bluetooth transmission delay should be as small as possible, the called device determines the bluetooth transmission delay according to the time when the called device receives the response message returned by the calling device and the time when the called device sends the synchronization request to the calling device, and if the bluetooth transmission delay is greater than a second threshold, that is, the bluetooth connection between the calling device and the called device is abnormal (at this time, the bluetooth transmission delay is large), the called device sends the synchronization request to the calling device again, wherein the second threshold is determined according to experience or simulation results, for example, the second threshold is 40 ms.
In step 103, if the time difference between the called device and the calling device is offset and the current time of the clock of the called device is t1, the called device determines the playing time t2 of the audio test data according to the following formula:
t2＝t1+offset
in implementation, because there may be noise when the calling device and the called device just establish a session, and there may be delay between the calling device and the called device, the called device determines the playing time of the audio test data after the session is established for a set time (e.g. 3s), and plays the audio test data to the calling device through the session, so as to reduce the influence of the noise and the delay of the calling device and the called device on the voice test.
In implementation, when the duration of session maintenance between the calling device and the called device is long, the called device plays voice test data to the calling device through the session at a set duration (e.g. 2s) every time, and the calling device periodically records the voice data received through the session until the session is ended. And if the playing time length of the audio data recorded by the calling equipment is less than the playing time length of the voice test data when the conversation is ended, discarding the recorded audio data.
Fig. 2 exemplarily shows a flow of another speech testing method provided by the embodiment of the present invention, where the flow mainly includes the following steps:
step 201: and the called device acquires the time difference between the calling device and the called device through the Bluetooth connection between the called device and the calling device according to the voice test request.
In the implementation, the method for acquiring the time difference between the calling device and the called device by the called device refers to the description in step 103, and is not described herein again.
Step 202: the calling device sends a call request to the called device to establish a session with the called device.
Step 203: and the called device determines the recording time of the audio data according to the time difference and the current time of the called device, records the audio test data played by the calling device through the session, and sends the recorded audio data to the voice test device. Optionally, the duration of the session is longer than the playing duration of the audio test data.
The voice test data is built in the calling equipment or provided by other equipment connected with the calling equipment. Specifically, if the voice test data is provided by another device connected to the calling device, at this time, the MIC of the calling device is connected to the another device, so that the calling device plays the voice test data to the called device through the another device.
Specifically, if the time difference between the called device and the calling device is offset and the current time of the clock of the called device is t1, the called device determines the recording time t4 of the audio data according to the following formula:
t4＝t1+offset
in implementation, because there may be noise when the calling device and the called device just establish a session, and there is a delay between the calling device and the called device, after the session is established for a set time (e.g. 3s), the calling device plays audio test data to the called device through the session, so as to reduce the influence of the noise and the delay of the calling device and the called device on a voice test. Specifically, the time t5 when the calling device plays the audio test data through the session is the current time of the calling device clock.
In implementation, when the duration of session maintenance between the calling device and the called device is long, the calling device plays voice test data to the calling device through the session at a set duration (e.g. 2s) every time, and the called device periodically records the voice data received through the session until the session is ended. And if the playing time length of the audio data recorded by the called equipment is less than the playing time length of the voice test data when the conversation is ended, discarding the recorded audio data.
Step 204: the voice test equipment determines the quality of the conversation according to the received audio data and the audio test data.
In practice, the method for determining the quality of the session by the voice test device is described in step 105, and is not described herein again.
In implementation, the calling device may also obtain a time difference between the calling device and the called device through bluetooth connection with the called device according to the voice test request, and perform time synchronization with the called device. Specifically, a calling device sends a synchronization request to a called device through a bluetooth connection with the called device, the synchronization request is used for acquiring the current time of a clock of the called device, the called device carries the current time of the clock of the called device in a response message and returns the response message to the calling device, the calling device takes the difference between the time of the clock when the calling device receives the response message and the time of the clock of the called device carried in the response message as the time difference between the called device and the calling device, and the called device sends the synchronization request to the calling device by adopting an NTP protocol. At this time, the calling device is an NTP Client, and the called device is an NTP Server.
Optionally, if the time difference obtained by the calling device is greater than the first threshold, the calling device obtains the time difference between the calling device and the called device through bluetooth connection with the calling device again. When the time difference acquired by the calling device is larger than the first threshold value, the calling device determines that the time of the calling device is asynchronous with that of the called device, and sends a synchronization request to the called device through Bluetooth connection with the called device again to perform time synchronization again without stopping voice testing or operation of a tester. Specifically, when the calling device performs a voice test, a synchronization request is sent to the called device at intervals of a set duration through bluetooth connection with the called device to monitor whether the called device and the calling device are synchronized, and when the called device and the calling device are not synchronized, a synchronization state is recovered in time.
Because the calling device is connected with the called device through the Bluetooth, the time difference between the called device and the calling device is obtained, and the time synchronization between the calling device and the called device is realized, so the time synchronization precision between the calling device and the called device is also influenced by the size of the Bluetooth transmission delay. In order to ensure the accuracy of time synchronization between the called device and the calling device, the bluetooth transmission delay should be as small as possible, the calling device determines the bluetooth transmission delay according to the time when the calling device receives the response message returned by the called device and the time when the calling device sends the synchronization request to the called device, and if the bluetooth transmission delay is greater than a second threshold, that is, the bluetooth connection between the calling device and the called device is abnormal (at this time, the bluetooth transmission delay is large), the called device sends the synchronization request to the calling device again, wherein the second threshold is determined according to experience or simulation results, for example, the second threshold is 40 ms.
It should be noted that, in the embodiment of the present invention, the voice testing method shown in fig. 1 and fig. 2 is directed to a session established between a calling device and a called device. In practical application, a plurality of sessions may be established between the calling device and the called device in one voice test plan, and a voice test is performed, at this time, step 101 to step 105 are executed for each session in the voice test plan, or step 201 to step 204 are executed, and the quality of each session is determined until the voice test plan is finished. Optionally, in a voice test plan, after a session between the calling device and the called device is ended, delaying for a set time length (for example, 5s), and performing a next voice test to determine the quality of a new session established between the calling device and the called device.
Based on the technical scheme, in the embodiment of the invention, the called device acquires the time difference between the calling device and the called device through the Bluetooth connection between the called device and the calling device according to the voice test request; the calling equipment sends a calling request to the called equipment according to the voice test request, and establishes a session with the called equipment; the called device determines the playing time of the audio test data according to the acquired time difference and the current time of the called device, and plays the audio test data to the calling device through the session, the calling device records the audio data received through the session and sends the recorded audio data to the voice test device, or the called device determines the recording time of the audio data according to the acquired time difference and the current time of the called device, records the audio test data played by the calling device through the session and sends the recorded audio data to the voice test device, wherein the duration of the session is longer than the playing duration of the audio test data; the voice test equipment determines the quality of the conversation according to the received audio data and the audio test data. The called device acquires the time difference between the calling device and the called device through the Bluetooth connection between the called device and the calling device, and performs time synchronization with the calling device, so that the reliability of the time synchronization of the tested device is improved, and the accuracy of a voice test result is improved.
