[0081] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the above-mentioned technologies, methods, and equipment should be considered as part of the specification.

[0082] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0083] It should be noted that, in the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. To facilitate the understanding of the embodiments of the present application, the present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0084] In order to solve the technical problem of low accuracy of Bluetooth audio test results in the prior art, the present application provides a Bluetooth audio test method, which can improve the accuracy of Bluetooth audio test results.

[0085] Figure 1A flow chart of a method for testing Bluetooth audio provided in an embodiment of the present application. This method can be applied to a test terminal. The test terminal may include one or more electronic devices such as a smart phone, a laptop computer, a desktop computer, a portable computer, a server, etc. In addition, the execution subject of this method may be hardware or software. When the execution subject is hardware, the execution subject may be one or more of the electronic devices. For example, a single electronic device may execute this method, or a plurality of electronic devices may cooperate with each other to execute this method. When the execution subject is software, this method may be implemented as a plurality of software or software modules, or as a single software or software module. No specific limitation is given here.

[0086] like Figure 1 As shown, the method specifically includes:

[0087] Step 101, after playing the target audio at the playback end, receiving the target audio collected by the microphone, wherein the target audio is the audio transmitted from the tested end to the playback end via Bluetooth.

[0088] In this embodiment, the playback end can be used to play the audio transmitted by the tested end via Bluetooth. As an example, the playback end can be a Bluetooth speaker.

[0089] The target audio may include any one or more audio segments of the tested end. As an example, the target audio may include voice audio.

[0090] The microphone can be used to collect the above target audio played by the playback end.

[0091] The tested end can be any device with a Bluetooth audio transmission function. As an example, the tested end can be a mobile phone with a Bluetooth audio transmission function, a computer with a Bluetooth audio transmission function, etc.

[0092] Step 102: extracting characteristic parameters of the target audio collected by the microphone to obtain actual characteristic parameters.

[0093] In this embodiment, the actual feature parameter may be a feature parameter of the target audio collected by the extracted microphone. As an example, the actual feature parameter may include at least one of the following: amplitude, frequency, Mel-scale Frequency Cepstral Coefficients (MFCC), fundamental tone, etc.

[0094] Step 103: determine standard feature parameters of the target audio in the test case.

[0095] In this embodiment, the standard characteristic parameter may be the characteristic parameter of the target audio included in the test case.

[0096] The standard feature parameter corresponds to the actual feature parameter. The standard feature parameter may include at least one of the following: amplitude, frequency, Mel-frequency cepstral coefficient, fundamental frequency, etc. Specifically, when the actual feature parameter includes amplitude, the standard feature parameter may also include amplitude.

[0097] It should be noted that the execution order of step 103 and step 101 and step 102 is not limited. For example, step 101 and step 102 may be executed first, and then step 103, or step 103 may be executed first, and then step 101 and step 102.

[0098] Step 104: Generate a test result based on the actual characteristic parameters and the standard characteristic parameters.

[0099] In this embodiment, the test result can be generated by comparing the similarity, error, inclusion relationship, etc. between the actual feature parameters and the standard feature parameters.

[0100] The test result may indicate whether the test on the target audio passes.

[0101] As an example, if the similarity between the actual feature parameters and the standard feature parameters is greater than or equal to a preset similarity threshold, then a test result indicating that the test passed can be generated; if the similarity between the actual feature parameters and the standard feature parameters is less than the above-mentioned preset similarity threshold, then a test result indicating that the test failed can be generated.

[0102] As another example, if the error between the actual feature parameters and the standard feature parameters is greater than or equal to a preset error threshold, then a test result indicating that the test failed can be generated; if the error between the actual feature parameters and the standard feature parameters is less than the above-mentioned preset error threshold, then a test result indicating that the test passed can be generated.

[0103] As another example, if the actual feature parameter is within the range represented by the standard feature parameter, then a test result indicating that the test passed can be generated; if the actual feature parameter is outside the range represented by the standard feature parameter, then a test result indicating that the test failed can be generated.

[0104] In some optional implementations of this embodiment, before the playback end plays the target audio, the following steps may also be performed:

[0105] The first step is to establish a connection with the tested end.

[0106] The second step is to determine the unique identifier of the playback terminal and obtain the target identifier.

[0107] The target identifier may be a unique identifier of the playback terminal, for example, the target identifier may be a MAC (Media Access Control Address, local area network address) address of the playback terminal.

[0108] The third step is to send the target identifier to the tested end, so that the tested end establishes a Bluetooth connection with the playback end through the target identifier.

[0109] Specifically, the tested end, the playback end and the microphone can be started, and the target identifier of the tested end can be determined to start the test. After starting the test, it can be determined whether the communication link between the test end and the tested end is successful. Afterwards, the test end turns on the Bluetooth function of the tested end through a communication interface such as a network port and a serial port, and searches for the target identifier of the playback end. Then, it can be determined whether the tested end searches for and obtains a specified target identifier. The tested end is paired and connected with the playback end according to the specified target identifier.

[0110] It can be understood that in the above optional implementation method, by determining the unique identifier of the playback end, the tested end can be more accurately controlled to establish a Bluetooth connection with the playback end, so that the specified playback end establishes a Bluetooth connection with the tested end, and this is recorded, which can facilitate subsequent restoration of the test scenario in order to analyze the test results.

[0111] In some optional implementations of this embodiment, the following method may be used to extract the characteristic parameters of the target audio collected by the microphone, thereby obtaining the actual characteristic parameters:

[0112] First, the silent part of the target audio collected by the microphone is cut off to obtain the non-silent audio.

[0113] Afterwards, feature parameters are extracted from the non-silent audio to obtain actual feature parameters.

[0114] The actual feature parameter may be a feature parameter extracted from non-silent audio.

[0115] It can be understood that in the above optional implementation method, the collected target audio is first preprocessed, that is, the silence at the beginning and end is removed to extract the characteristic parameters in the non-silent audio. This can reduce interference to subsequent steps and thus improve the accuracy of test result generation.

[0116] In some optional implementations of this embodiment, the following method may be used to extract the characteristic parameters of the target audio collected by the microphone, thereby obtaining the actual characteristic parameters:

[0117] First, the target audio collected by the microphone is transformed into a frequency domain to obtain a frequency domain signal.

[0118] The frequency domain signal may be a signal obtained by performing frequency domain transformation on the target audio collected by a microphone.

[0119] Afterwards, characteristic parameters are extracted from the frequency domain signal to obtain actual characteristic parameters.

[0120] The actual characteristic parameter may be a characteristic parameter extracted from the frequency domain signal.

[0121] It can be understood that in the above optional implementation, the accuracy of the test result can be further improved by extracting characteristic parameters in the frequency domain signal.

[0122] In some application scenarios of the above optional implementations, the following method may be used to extract characteristic parameters from the frequency domain signal, thereby obtaining actual characteristic parameters:

[0123] Firstly, frequency characteristic parameters and amplitude characteristic parameters are extracted from the frequency domain signal.

[0124] Afterwards, the frequency characteristic parameter and the amplitude characteristic parameter are determined as actual characteristic parameters.

[0125] It can be understood that in the above application scenarios, the Bluetooth audio test can be performed by comparing the frequency characteristic parameters and amplitude characteristic parameters of the target audio collected by the microphone with the frequency characteristic parameters and amplitude characteristic parameters in the test case. In this way, the accuracy of the Bluetooth voice test result generation can be further improved.

[0126] In some optional implementations of this embodiment, before generating the test result based on the actual characteristic parameter and the standard characteristic parameter, the Bluetooth signal strength between the playback end and the tested end may also be determined.

[0127] On this basis, the following method can be used to generate test results based on the actual characteristic parameters and the standard characteristic parameters:

[0128] A test result is generated based on the Bluetooth signal strength, the actual characteristic parameter and the standard characteristic parameter.

[0129] Here, the target audio test is meaningful only when the signal strength falls within a certain range, that is, the signal is neither too strong nor too weak. In this case, there will be no saturation due to too strong a signal, nor will there be any decoding error due to too weak a signal.

[0130] It can be understood that in the above optional implementation, by comparing the actual characteristic parameters with the standard characteristic parameters with reference to the Bluetooth signal strength and then generating the test result, the accuracy of the test result generation can be further improved.

[0131] The Bluetooth audio test method provided in the embodiment of the present application is applied to the test end, which can receive the target audio collected by the microphone after the target audio is played on the playback end, wherein the target audio is the audio transmitted from the tested end to the playback end via Bluetooth, and then extract the characteristic parameters of the target audio collected by the microphone to obtain the actual characteristic parameters, and determine the standard characteristic parameters of the target audio in the test case, and finally, generate the test results based on the actual characteristic parameters and the standard characteristic parameters. Thus, by testing and simulating the actual Bluetooth audio usage scenario to generate the Bluetooth audio test results, the accuracy of the Bluetooth audio test results can be improved.

[0132] Figure 2 A flowchart of another method for testing Bluetooth audio provided in an embodiment of the present application. The method is applied to a test terminal. The test terminal is used to test the audio transmitted by multiple test terminals via Bluetooth. The test terminals, the microphones, the playback terminals and the shielding box correspond one to one.

[0133] like Figure 2 As shown, the method specifically includes:

[0134] Step 201, when a microphone, a playback end and the tested end having a corresponding relationship are arranged in a corresponding shielding box, after the target audio is played at the playback end, the target audio collected by the microphone is received, wherein the target audio is the audio transmitted from the tested end to the playback end via Bluetooth.

[0135] In this embodiment, a microphone, a playback terminal and a tested terminal may be placed in each shielding box. The microphone, the playback terminal and the tested terminal placed in the shielding box correspond to the shielding box.

[0136] Shielding box can be used to prevent interference from external electromagnetic waves and sound sources.

[0137] In addition, step 201 and Figure 1 Step 101 in the corresponding embodiment is basically the same and will not be described again here.

[0138] Step 202: extract characteristic parameters of the target audio collected by the microphone to obtain actual characteristic parameters.

[0139] In this embodiment, step 202 and Figure 1 Step 102 in the corresponding embodiment is basically the same and will not be described again here.

[0140] Step 203: determine the standard feature parameters of the target audio in the test case.

[0141] In this embodiment, step 203 and Figure 1 Step 103 in the corresponding embodiment is basically the same and will not be described again here.

[0142] Step 204: Generate a test result based on the actual characteristic parameters and the standard characteristic parameters.

[0143] In this embodiment, step 204 and Figure 1 Step 104 in the corresponding embodiment is basically the same and will not be described again here.

[0144] It should be noted that, in addition to the above contents, this embodiment may also include Figure 1 The corresponding technical features described in the corresponding embodiments are realized Figure 1 For technical effects of the Bluetooth audio test method shown, please refer to Figure 1 For the sake of brevity, the relevant description is not repeated here.

[0145] In the Bluetooth audio testing method provided in the embodiment of the present application, each test end can be used to test the Bluetooth audio of multiple tested ends, and each tested module (including a microphone, a tested end, a playback end and a shielding box with a corresponding relationship) is independent of each other and does not affect each other. Therefore, the method can test the Bluetooth audio of multiple tested ends at the same time, thereby improving the testing efficiency of the Bluetooth audio.

[0146] The following is an illustrative description of the embodiments of the present application, but it should be noted that the embodiments of the present application may have the features described below, but the following description does not constitute a limitation on the scope of protection of the embodiments of the present application.

[0147] Among the existing Bluetooth audio test solutions, there is an adaptive Bluetooth test system, which includes an intelligent Bluetooth test unit and a monitoring storage unit. The system can realize the automated testing of characteristic indicators such as Bluetooth transmission power, clock frequency, and sensitivity. However, this test method requires the use of dedicated test equipment, and the test efficiency is low, which is not suitable for mass production testing.

[0148] In addition, there is a Bluetooth test system and method, which can realize the simultaneous testing of multiple Bluetooth devices based on the BLE (Bluetooth Low Energy) FPGA (Field Programmable Gate Array) development board, greatly improving the test efficiency. However, the test system needs to develop a dedicated test tool, and the Bluetooth communication adopts the test instructions and data stream mode, which cannot test and simulate the real use scenario of Bluetooth voice.

[0149] In order to test the real scene of simulating Bluetooth voice, there is also a Bluetooth test device and a Bluetooth test system using the device. The device includes a radio frequency circuit and a baseband circuit, and the audio output interface of the baseband circuit is connected to an external speaker. Due to the addition of an external speaker, the tester does not have to wear a Bluetooth headset for testing. However, this test method requires the tester to try to pair and connect according to the Bluetooth device to be tested, and after the pairing is successful, initiate the test of the data communication function. The pairing process is complicated. In addition, the manual test method has problems such as human misjudgment and inconsistent test standards, and its voice quality cannot be guaranteed.

[0150] In summary, the existing Bluetooth tests have the following deficiencies:

[0151] (1) The development cost of developing dedicated Bluetooth test equipment is high. A complete set of test tools and test systems need to be developed for specific Bluetooth devices, and the universality of the test tools and test systems is poor.

[0152] (2) Most Bluetooth tests use test commands and data streams as a communication method, which cannot test and simulate actual customer usage scenarios.

[0153] (3) The Bluetooth voice test method has a low degree of automation, the manual test method is subject to human error, and the test standards cannot be unified, etc., which are quality risks.

[0154] In view of this, the present method provides a method and system for automated testing based on Bluetooth voice, which can be used for production testing and functional inspection of Bluetooth devices. A microphone can be used to collect the simulated sound signal (i.e., the target audio) emitted by a Bluetooth speaker (i.e., the playback end) connected to the Bluetooth device to be tested (i.e., the tested end) to generate a corresponding audio file, and then the test platform (i.e., the test end) calls the voice algorithm to process the audio file, quantify the test standard by extracting the characteristic parameters of the sound, and finally automatically judge and draw the test conclusion. The present method can improve the efficiency of Bluetooth automated testing and the reliability of test results, quantify test standards, reduce development costs, test and simulate real customer usage scenarios, and has high versatility and strong scalability.

[0155] The method may include the following steps:

[0156] 1) Start the Bluetooth device, Bluetooth speaker and microphone to be tested. Scan the serial number of the Bluetooth device to be tested to start the test.

[0157] 2) Determine whether the communication link between the PC (i.e. the above-mentioned test terminal) and the Bluetooth device to be tested is successful.

[0158] 3) The PC test platform (that is, the test end mentioned above) turns on the Bluetooth function of the Bluetooth device to be tested through communication interfaces such as the network port and the serial port, and searches for the Bluetooth MAC address of the Bluetooth speaker.

[0159] 4) Determine whether the Bluetooth device to be tested has searched and obtained a specified Bluetooth MAC address.

[0160] 5) The Bluetooth device to be tested pairs and connects with the Bluetooth speaker according to the specified Bluetooth MAC address. The Bluetooth device to be tested calculates the Bluetooth signal strength and feeds it back to the PC test platform.

[0161] 6) The Bluetooth device under test controls the Bluetooth speaker through the Bluetooth interface to play a standardized audio file (that is, the target audio mentioned above), which is collected by the microphone and transmitted to the PC to generate an audio file such as WAV.

[0162] 7) Turn off the Bluetooth adapter of the device under test. The PC test platform calls the voice algorithm to process the collected audio files, compares the processed sound characteristic parameters (that is, the actual characteristic parameters mentioned above) with the test standards (that is, the standard characteristic parameters mentioned above), and returns the test results, which are uploaded and saved to the test database.

[0163] Specifically, if Figure 3 As shown, Figure 3 A flowchart of another method for testing Bluetooth audio provided in an embodiment of the present application. The method comprises the following steps:

[0164] Step 301: Start the Bluetooth device, Bluetooth speaker and microphone to be tested. Ensure that the Bluetooth device to be tested is connected to the PC through a communication interface such as an Ethernet port or a serial port, and ensure that the Bluetooth speaker is in a search state. Scan the serial number of the Bluetooth device to be tested, and the test platform starts testing.

[0165] In a specific application, the test platform refers to the MAT (MTE Auto Test) production test platform, and the scanner automatically scans the serial number of the Bluetooth device to be tested to obtain the required test cases.

[0166] Step 302: Determine whether the communication link between the PC and the Bluetooth device to be tested is successful.

[0167] In a specific application, the PC can send a link establishment request to the Bluetooth device to be tested, and the Bluetooth device to be tested will return a response message after receiving the link establishment request, that is, the link establishment is successful. If the communication link between the PC and the Bluetooth device to be tested is successful within the preset time, the next Bluetooth test will begin; if not, the PC will repeatedly send the link establishment request to the Bluetooth device to be tested within the preset time, until the link establishment time exceeds the preset time, the PC does not receive the response message, the test is terminated, and the test is returned to step 301 to restart.

[0168] Step 303: The PC test platform turns on the Bluetooth function of the Bluetooth device to be tested through a communication interface such as an Ethernet port or a serial port, and searches for and obtains the Bluetooth MAC address of the Bluetooth speaker.

[0169] In a specific application, after the PC establishes a link with the Bluetooth device to be tested, it sends a request to the Bluetooth device to turn on the Bluetooth function. The Bluetooth device to be tested turns on the Bluetooth function and searches for all Bluetooth devices around it, and parses the MAC addresses of all Bluetooth devices within the search range.

[0170] Step 304: Determine whether the Bluetooth device to be tested has searched and obtained the target Bluetooth MAC address.

[0171] In a specific application, the PC can transmit a specified target Bluetooth MAC address to the Bluetooth device under test. The Bluetooth device under test automatically pairs and connects to the target Bluetooth speaker based on the target Bluetooth MAC address. Within a preset time, if the Bluetooth device under test searches for a Bluetooth MAC address that contains the target Bluetooth MAC address, the device under test is paired and connected to the Bluetooth speaker; otherwise, the Bluetooth device under test repeatedly feeds back to the PC within a preset time that the search for the target Bluetooth MAC address has failed until the number of feedbacks exceeds the preset number, and the PC test platform pops up a box prompting "Bluetooth connection failed, please reopen the Bluetooth speaker and make sure the Bluetooth speaker is in search status". If the search still fails, the test terminates and returns to step 301 to restart the test.

[0172] Step 305: The Bluetooth device to be tested can be paired and connected with the Bluetooth speaker according to the specified Bluetooth MAC address. The Bluetooth device to be tested calculates the Bluetooth signal strength and feeds it back to the PC test platform.

[0173] Step 306: The Bluetooth device under test controls the volume of the Bluetooth speaker through the Bluetooth interface and plays a standardized audio file, which is collected by the microphone and transmitted to the PC to generate an audio file in WAV format. In order to distinguish the audio files of each device under test, the serial number of the Bluetooth device under test can be used to name the audio file.

[0174] Step 307: turn off the Bluetooth adapter of the device under test; the PC test platform calls the voice algorithm to process the collected audio file, compares the processing result with the test standard, and returns the test result, which is uploaded and saved to the test database.

[0175] In specific applications, the collected audio files are first preprocessed, and the silence at the beginning and end needs to be removed to reduce interference with subsequent steps. After the sound signal preprocessing is completed, the characteristic parameters of the sound are extracted after frequency domain transformation. For example, the range and amplitude of the main frequency of the sound signal, the range and amplitude of other secondary frequencies, etc. can be analyzed, and characteristic indicators such as the range of the main frequency and the amplitude ratio of the main frequency to other secondary frequencies are calculated, and the Bluetooth signal strength index obtained in step 305 is compared with the test standard. All the acquired test data are automatically judged as passed within the test standard, otherwise, the test fails. The test results and test data are uploaded and saved to the test database. The test database implements platform management and control, so that the test data can be queried and the test process can be controlled.

[0176] The example of the present invention realizes the automatic test based on Bluetooth voice by playing, collecting and processing audio files by algorithm, which improves the efficiency of Bluetooth automatic test and the stability of test results. The test system can test and simulate the real usage scenarios of customers and has high versatility and strong scalability.

[0178] The test method of Bluetooth audio provided in the embodiment of the present application plays a standard audio through the Bluetooth function, and uses a voice algorithm to process the collected audio file, thereby realizing an automated test based on Bluetooth voice. In addition, in this method, a section of audio can also be played through the Bluetooth function, and other devices recognize the audio and perform corresponding operations. By this method, the efficiency of Bluetooth automated testing and the reliability of test results can be improved, and parallel testing of multiple Bluetooth devices to be tested can be realized without interfering with each other. The test process does not require manual intervention, which can effectively avoid the behavior of manual misjudgment. In addition, the actual use scenario of customers can be tested and simulated. The real scenario of playing audio when the customer uses the Bluetooth device is simulated, and the collected sound signal is processed by the voice algorithm, and the test standard is quantified by the characteristic parameters of the sound. The cost of developing test equipment is effectively reduced. There is no need to develop dedicated Bluetooth test equipment. Using the Bluetooth speakers, microphones, shielding boxes that are easily purchased on the market, and the computer program products in the embodiments of the present invention, a set of automated test systems based on Bluetooth voice can be built.
