[0044] Before describing the embodiments of the present application in detail, some related technologies involved in the embodiments of the present application are first described as follows:

[0045] When there are multiple sound sources in a smart cockpit at the same time, it is a common design to mix multiple audios, such as mixing music and instrument indicator sounds played at the same time. However, in the process of developing the mixing algorithm, the mixing algorithm needs to be verified and tested to improve the reliability of the mixing algorithm. However, the related technology lacks effective testing methods, which makes it impossible to fully evaluate the performance and effect of the mixing algorithm, so it is impossible to find potential problems and improvement space of the mixing algorithm, resulting in the need for R&D personnel to adjust the mixing algorithm through continuous trial and error, which increases the trial and error cost and time investment in the development process, and also reduces the user experience. Therefore, it is necessary to propose an effective testing method for the mixing algorithm to improve the reliability and user experience of the smart cockpit.

The cloud server, the server can also be a node server in the blockchain network; the software can be an application that implements the mixing algorithm test method, etc., but is not limited to the above forms.

[0048] The present application can be used in many general or special computer system environments or configurations.

[0049] Reference Figure 1 , the embodiment of the present application provides a mixing algorithm testing method, the method may include but is not limited to including S100 to S130, specifically as follows:

[0050] S100: Processing a sound source audio using a sound mixing algorithm and playing the sound source audio, and measuring a response time of the sound mixing algorithm to the sound source audio.

[0051] It can be understood that the mixing algorithm of this embodiment can process multiple different audios for simultaneous playback. For example, the audio sources that can be processed and played by the mixing algorithm include: telephone audio, audio played by a player, welcome words, navigation voice, broadcast audio, radar prompt sound, media audio, instrument indicator sound, acoustic vehicle warning sound or engine noise enhancement sound.

[0052] The mixing algorithm can process various audios, such as adjusting the sound intensity, playback order, and playback frequency of each audio. In order to test the response performance of the mixing algorithm, this embodiment can use the mixing algorithm to mix each audio and then play the audio obtained after the mixing process, and measure the time interval from processing each audio to playing the audio as the response time. Generally, the shorter the response time, the stronger the performance of the mixing algorithm.

[0053] Reference Figure 2 The step of measuring the response time of the mixing algorithm to the source audio in S100 may further include the following steps:

[0054] S101: Using RT-Tester to measure the response time of the mixing algorithm to the source audio.

[0055] It is understandable that in this embodiment, a real-time performance testing tool, such as RT-Tester, can be used to measure the response time of the mixing algorithm. For example, by simulating the audio input of the sound source under different loads and scenarios, the response time of the mixing algorithm is tested to determine the processing delay, which can provide test data for the mixing algorithm to meet the real-time requirements.

[0056] Specifically, RT-Tester is a general test system that integrates automated semi-physical testing, instantiation of different types of hardware interfaces, and software integration testing of operating systems. It consists of a series of components and supports multiple languages ​​such as C, C++, Java, and C#. It is used in various test stages such as unit testing, integration testing, configuration item testing, software and hardware integration testing, and system testing. It automatically generates test cases, executes tests, and conducts real-time test evaluation during the test process.

[0057] RT-Tester can automatically generate test cases, test data and test processes, is compatible with specifications in multiple formats (UML2.0, Domain-Specific language, CSP, etc.), and generates and maintains a traceability matrix of requirements, test cases, test processes and test results.

[0058] RT-Tester has its own runtime environment, based on the lightweight process mechanism of the underlying Windows or Linux operating system, managing configurable user threads on LWP, and the cost of context switching is not high. In Linux multi-core and multi-CPU platforms, the capabilities of RT-Tester are enhanced with the help of Hard Real-Time Linux kernel patch. A specified number of CPUs can be reserved for RT-Tester's LWPs, which makes the scheduling accuracy about a few microseconds. In the remaining cores or CPUs, other programs can be executed normally without affecting the system during real-time runtime.

[0059] S110: using the sound mixing algorithm to recognize a test voice, and measuring the recognition accuracy and recognition time of the sound mixing algorithm for the test voice.

[0060] It can be understood that the mixing algorithm of this embodiment can process externally input voice, which can be a voice command. Therefore, this embodiment can input a test voice command as a test voice into the mixing algorithm, use the mixing algorithm to recognize the voice command, and then test the recognition accuracy of the mixing algorithm for the voice command based on the recognition result, and test the time interval from inputting the voice command to obtaining the recognition result as the recognition time.

[0061] Reference Figure 3 The step of using the mixing algorithm to recognize the test speech in S110 may further include the following steps:

[0062] S111: Inputting simulated voice and / or real user voice as the test voice into the mixing algorithm for recognition.

[0063] It can be understood that the present embodiment can use simulated generated voice or user's real voice and other voice commands as test voice input to the mixing algorithm for recognition. For example, the present embodiment can use a voice recognition test tool to test the recognition accuracy of the mixing algorithm for voice commands. By simulating voice input or using real voice data, the accuracy and response time of voice recognition are measured to test whether the audio processing method of the mixing algorithm affects the recognition accuracy and speed of voice commands.

[0064] S120: Analyze the audio features of the mixed audio processed by the mixing algorithm to obtain an analysis result.

[0065] Exemplarily, the audio features that can be analyzed in this embodiment may include features such as spectrum features or distortion levels, so as to test whether the mixed audio processed by the mixing algorithm damages the sound quality or introduces additional noise.

[0066] Reference Figure 4 , S120 may further include:

[0067] S121: Analyze the audio features of the mixed audio processed by the mixing algorithm using a mixed signal analysis instrument to obtain an analysis result.

[0068] Exemplarily, this embodiment can use a mixed signal analysis instrument such as an oscilloscope or a spectrum analyzer to perform real-time monitoring and analysis on the mixed audio obtained after the mixing algorithm is processed, so as to detect the spectral characteristics, degree of distortion and other characteristics of the mixed audio, and then test whether the mixed audio processed by the mixing algorithm damages the sound quality or introduces additional noise.

[0069] S130: Using the mixing algorithm to process the test audio to obtain a processing result, and comparing the processing result with an expected result to obtain verification data of the mixing algorithm.

[0070] It can be understood that in order to understand the actual processing effect of the mixing algorithm, the present embodiment can use the mixing algorithm to process the test audio, wherein the test audio may include multiple different types of audio, such as communication, navigation, media, and broadcast audio, and then obtain the mixed processing result of the mixing algorithm on various types of audio, and then compare the processing result with the estimated result, for example, compare the spectral characteristics, distortion degree or signal-to-noise ratio and other indicators of the two, and then obtain verification data, and then verify the performance of the mixing algorithm based on the verification data.

[0071] Reference Figure 5 The step of using the mixing algorithm to process the test audio to obtain a processing result in S130 may further include the following steps:

[0072] S131: Utilize a digital signal processing chip to execute the mixing algorithm, so as to utilize the mixing algorithm to process the test audio and obtain a processing result.

[0073] By way of example, the present embodiment can verify the performance and effect of the mixing algorithm through algorithm simulation and actual testing. For example, the algorithm simulation is performed using software such as MATLAB to verify the mixed audio processing effect of the mixing algorithm in different scenarios. At the same time, actual testing is performed using a digital signal processing (DSP) chip or a real-time audio processor to evaluate the performance and effect of the mixing algorithm.

[0074] Next, the solution of the embodiment of the present application will be introduced and explained in conjunction with specific application examples:

[0075] Exemplarily, this embodiment can test the mixing algorithm deployed in the smart cockpit, wherein the smart cockpit can be mounted on various vehicles. Specifically, the vehicle can be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle can also be an operating vehicle, such as a van, bus, small truck or large trailer. The vehicle can be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0076] Specifically, this embodiment can perform the following tests on the mixing algorithm:

[0077] 1. Real-time performance test:

[0078] Use RT-Tester or similar real-time performance testing tools to perform performance testing of the mixing algorithm in a real-time environment that simulates a smart cockpit. By sending audio source trigger signals of different priorities and frequencies to emit corresponding audio sources, monitor the response time of the mixing algorithm to various audio sources and the processing delay time.

[0079] Specifically, RT-Tester is a general test system that integrates automated semi-physical testing, instantiation of different types of hardware interfaces, and software integration testing of operating systems. It consists of a series of components and supports multiple languages ​​such as C, C++, Java, and C#. It is used in various test stages such as unit testing, integration testing, configuration item testing, software and hardware integration testing, and system testing. It automatically generates test cases, executes tests, and conducts real-time test evaluation during the test process.

[0080] RT-Tester can automatically generate test cases, test data and test processes, is compatible with specifications in multiple formats (UML2.0, Domain-Specific language, CSP, etc.), and generates and maintains a traceability matrix of requirements, test cases, test processes and test results.

[0081] RT-Tester has its own runtime environment, based on the lightweight process mechanism of the underlying Windows or Linux operating system, managing configurable user threads on LWP, and the cost of context switching is not high. In Linux multi-core and multi-CPU platforms, the capabilities of RT-Tester are enhanced with the help of Hard Real-Time Linux kernel patch. A specified number of CPUs can be reserved for RT-Tester's LWPs, which makes the scheduling accuracy about a few microseconds. In the remaining cores or CPUs, other programs can be executed normally without affecting the system during real-time runtime.

[0082] 2. Speech recognition accuracy test:

[0083] Use the speech recognition test platform to simulate the voice interaction scenario in the smart cockpit, send different voice commands to the mixing algorithm, play media sound sources at the same time, evaluate the speech recognition accuracy and response time of the mixing algorithm under mixing conditions, and record the recognition results and processing time of the mixing algorithm for voice commands.

[0084] 3. Mixed audio analysis:

[0085] Connect a signal analysis instrument such as an oscilloscope or spectrum analyzer to the audio output port of the smart cockpit, play and drive various audio sources to play audio at the same time, monitor the mixed audio obtained after the mixing algorithm is processed, and perform spectrum analysis and distortion detection on the mixed audio to evaluate the audio quality and noise level of the mixed audio.

[0086] 4. Mixing algorithm performance verification:

[0087] Implement the mixing algorithm on the digital signal processing (DSP) chip, and verify the performance and effect of the mixing algorithm through simulation scenarios and actual tests. Use simulated audio signals or actual recorded car audio data to input into the mixing algorithm, obtain the processing results after the mixing algorithm processes the audio, and compare and analyze the processing results with the expected results.

[0088] This embodiment can efficiently and comprehensively test the mixing algorithm, and can specifically adjust and optimize the mixing algorithm according to the test results, thereby improving the testing efficiency of the mixing algorithm. The optimized mixing algorithm can accurately identify different audios and perform appropriate mixing processing, thereby achieving timely communication of important information, reducing noise interference and improving audio quality, thereby improving the user's auditory experience in various scenarios.
