[0018] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present application. However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0019] A method and device for feedback of a vehicle-mounted voice signal according to an embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0020] Figure 1 1 is a flow chart of a method for feedback of a vehicle-mounted voice signal provided in an embodiment of the present application. The method for feedback of a vehicle-mounted voice signal includes:

[0021] 101, obtaining a vehicle command corresponding to the vehicle voice signal, traversing a command library configured for the vehicle based on the vehicle command, and determining a type of the vehicle command;

[0022] 102, if the vehicle command is an asynchronous type command, determine the execution success rate of the vehicle command according to the vehicle evaluation data of the current vehicle and the historical execution success rate of the vehicle command executed by the relevant vehicle;

[0023] 103, when the execution success rate of the vehicle command is greater than a preset success rate threshold, responding to the vehicle voice signal through an asynchronous feedback method based on the vehicle command;

[0024] 104 , if the vehicle command is a synchronous type command, respond to the vehicle voice signal through a synchronous feedback method based on the vehicle command.

[0025] In step 101, it is exemplified that the vehicle command corresponding to the on-board voice signal is obtained, and the command library of the vehicle configuration is traversed based on the vehicle command to determine the type of vehicle command. For example, a vehicle model command library can be constructed based on the automobile software management platform system, and a vehicle command library can be formed based on the basic configuration and rights information of the vehicle. The basic configuration refers to the built-in functions of different vehicle versions, such as seat heating, intelligent assisted driving, etc., and the rights information refers to different rights for the same function, such as advanced intelligent driving services and ordinary services. Different command libraries are constructed based on different vehicle models, and the vehicle commands are preliminarily judged based on the type of commands in the command library to determine whether the vehicle commands are synchronous type commands or asynchronous type commands. Figure 2As shown, obtaining the vehicle command corresponding to the vehicle voice signal includes obtaining voice data in the voice system by receiving the voice containing the vehicle command issued by the user, and then converting the voice data into text through digital signal processing and natural language processing, and performing text semantic recognition in the voice processing system to parse the vehicle command. In some implementation processes, when classifying the commands in the command library, the commands can also be classified based on whether they are vehicle control commands. For example, vehicle control commands can all be synchronous command types, while non-vehicle control commands can be asynchronous command types. Among them, vehicle control commands include commands such as turning on navigation, and non-vehicle control commands include commands such as upgrading at 8 pm, charging at midnight, and turning on the air conditioner at home.

[0026] In step 102, it is exemplified that if the vehicle instruction is an asynchronous type instruction, the execution success rate of the vehicle instruction is determined based on the vehicle evaluation data of the current vehicle and the historical execution success rate of the vehicle instruction executed by related vehicles. For example, when it is confirmed that the vehicle instruction is initially judged to be an asynchronous type instruction, it does not mean that the vehicle instruction must adopt an asynchronous feedback method, and it is necessary to further predict the execution success rate of the vehicle instruction this time. In some implementation processes, the execution success rate this time can be predicted by vehicle evaluation data and historical execution success rate, wherein the vehicle evaluation data includes mileage data, vehicle usage habit data and vehicle age data.

[0027] In step 103, it is exemplified that when the execution success rate of the vehicle command is greater than the preset success rate threshold, based on the vehicle command, the vehicle voice signal is responded to through an asynchronous feedback method. For example, the asynchronous feedback method can provide preliminary feedback on the execution result while executing the vehicle command, without waiting for the execution of the vehicle command to be completed before feedback. Therefore, in order to ensure the accuracy of the asynchronous feedback, the execution success rate of the vehicle command can be predicted. If the execution success rate is greater than the preset success rate threshold, the vehicle voice signal is responded to through an asynchronous feedback method, wherein the preset success rate threshold can be set to 50%, which is not specifically limited here. On the contrary, if the execution success rate is less than the preset success rate threshold, then even if the vehicle command is an asynchronous command type, synchronous feedback is performed to ensure the accuracy of the feedback execution result and improve the user's car experience.

[0028] In step 104, it is exemplified that if the vehicle command is a synchronous type command, based on the vehicle command, the vehicle voice signal is responded to by a synchronous feedback method. For example, the synchronous feedback method must be fed back after the vehicle command is executed, such as Figure 2 As shown, when the vehicle command is a synchronous type command, the vehicle voice signal is directly responded to through synchronous feedback, and the vehicle command is sent to the voice execution system for execution.

[0029] According to the technical solution provided in the embodiment of the present application, it can be applied to an in-vehicle voice interaction system. When a user sends a corresponding vehicle command through an in-vehicle voice signal, the vehicle configuration command library is traversed based on the vehicle command corresponding to the in-vehicle voice signal to confirm whether the vehicle command is an asynchronous type command or a synchronous type command. When the vehicle command is an asynchronous type command, the execution success rate of the vehicle command is calculated based on the vehicle evaluation data and the historical execution success rate of the current vehicle. By comparing the execution success rate with a preset success rate threshold, it is finally confirmed whether the vehicle command responds to the user's in-vehicle voice signal through asynchronous feedback, thereby further improving the feedback efficiency when the user interacts through in-vehicle voice.

[0030] In some embodiments, an instruction library configured for the vehicle is traversed based on the vehicle instructions to determine the type of the vehicle instruction, including: obtaining the fault tolerance rate of executing each instruction in the instruction library, classifying each instruction according to the fault tolerance rate, and obtaining asynchronous type instructions and synchronous type instructions; matching instruction library instructions that are identical to the vehicle instructions from the instruction library, and determining the type of the vehicle instruction based on the type of the identical instruction library instructions.

[0031] Specifically, the fault tolerance rate refers to the degree of influence of each vehicle command on driving. For example, switching navigation, starting and stopping headlights, etc., once feedback is given, it will affect driving. Therefore, in order to improve the feedback effect without affecting driving, the commands with a high degree of influence on driving and a low fault tolerance rate are synchronous type commands, while the commands with a low degree of influence on driving and a high fault tolerance rate are asynchronous type commands, such as Figure 2 As shown, a query is performed in the instruction library according to the vehicle instruction to determine the type of the vehicle instruction.

[0032] In some embodiments, the execution success rate of vehicle instructions is determined based on the vehicle evaluation data of the current vehicle and the historical execution success rate of vehicle instructions executed by related vehicles, including: determining related vehicles of the same model as the current vehicle, calculating the cosine similarity of the vehicle evaluation data between the current vehicle and the related vehicles, and obtaining a vehicle age coefficient, a vehicle usage habit coefficient, and a mileage coefficient, wherein the vehicle evaluation data includes vehicle age data, vehicle usage habit data, and mileage data; obtaining the historical execution success rate of the related vehicles, calculating the product of the vehicle age coefficient, the vehicle usage habit coefficient, the mileage coefficient and the historical execution success rate, and obtaining the execution success rate of the vehicle instructions.

[0033] Specifically, the predicted execution success rate of the current vehicle executing the vehicle command can be calculated through the related vehicles of the current vehicle. First, multiple vehicles of the same model as the current vehicle are determined, and then the cosine similarities of the age data, vehicle usage habit data, and mileage data of the current vehicle and the multiple vehicles of the same model are calculated respectively. Among them, the vehicle corresponding to the minimum cosine similarity is the most relevant vehicle of the current vehicle, which means that the most relevant vehicle is most similar to the current vehicle in terms of age, vehicle usage habits, and mileage. Therefore, the most relevant vehicle can be used as a reference to obtain the historical execution success rate of the most relevant vehicle. At the same time, the similarity coefficient between the most relevant vehicle and the current vehicle is calculated to obtain the vehicle age coefficient, vehicle usage habit coefficient, and mileage coefficient. The product of the historical execution success rate, vehicle age coefficient, vehicle usage habit coefficient, and mileage coefficient is calculated, which is the predicted execution success rate.

[0034] In some embodiments, when the execution success rate of a vehicle command is greater than a preset success rate threshold, the vehicle voice signal is responded to through an asynchronous feedback method based on the vehicle command, including: when the execution success rate of the vehicle command is greater than the preset success rate threshold, feedback is given that the vehicle execution is successful, and the vehicle command is executed to obtain a first execution result; the first execution result is polled, and if the polled first execution result is an execution failure, the reason for the execution failure is obtained to update the historical execution success rate; when the execution success rate of the vehicle command is less than the preset success rate threshold, the vehicle command is executed to obtain a second execution result, and the second execution result is fed back.

[0035] Specifically, when the vehicle command responds through asynchronous feedback and obtains the first execution result, it is necessary to poll the first execution result, for example, poll the first execution result once every 500 milliseconds, and end the polling if the execution result is polled. If the first execution result is successful, the process ends; if the first execution result is failed, the failure reason is obtained. In some implementation processes, such as Figure 2 As shown, the failure reason can also be announced through the power amplifier system by converting text to speech.

[0036] In some embodiments, instruction library instructions identical to vehicle instructions are matched from an instruction library, and the type of vehicle instructions is determined based on the type of the identical instruction library instructions, including: determining whether instruction library instructions identical to vehicle instructions are obtained from the instruction library; if the identical instruction library instructions are not obtained, the vehicle instructions are not executable, and the non-executable type of the vehicle instructions is confirmed, wherein the non-executable type includes an unexecutable type and an execution to be upgraded type; if the identical instruction library instructions are obtained, the vehicle instructions are executable, and the type of vehicle instructions is determined based on the instruction library instructions.

[0037] Specifically, before determining the type of vehicle instruction, it is also necessary to determine whether the vehicle instruction is executable. When the instruction library instruction that is the same as the vehicle instruction cannot be found through the instruction library, the vehicle instruction is not executable. At the same time, the unexecutable type of the vehicle instruction is determined, where the unexecutable type means that the vehicle itself does not have the conditions to execute the vehicle instruction; the execution to be upgraded type means that the vehicle is executable but the user does not have permission. For example, the user has not purchased the seat heating function, and the user needs to be prompted to purchase and upgrade before use.

[0038] In some embodiments, when the execution success rate of a vehicle instruction is less than a preset success rate threshold, the vehicle instruction is executed to obtain a second execution result. After the second execution result is fed back, it also includes: if the execution of the vehicle instruction fails, the vehicle instruction is repeatedly executed and the number of repeated executions is obtained; when the execution result is changed to successful execution of the vehicle instruction, the execution success result is fed back, or when the number of repeated executions is equal to the preset execution number, the execution failure result is fed back.

[0039] Specifically, to further improve the feedback effect, when executing synchronous feedback or asynchronous feedback, if the execution result is an execution failure, it is necessary to repeat the execution of the vehicle instruction until the execution is successful and then feedback is given, or, when the vehicle instruction is repeated for a preset number of times, the execution failure result is fed back, wherein the preset number of executions can be 3 times, which is not specifically limited here. In other implementation processes, after the execution fails, the execution failure data can also be obtained and uploaded, so as to recalculate the historical execution success rate based on the failure data, and use it as the basis of the algorithm library for judging the execution success rate the next time this vehicle or other vehicles execute the same instruction. Among them, the execution failure data includes the reason for the failure,

[0040] In some embodiments, if the vehicle command is a synchronous type command, after responding to the vehicle voice signal through synchronous feedback based on the vehicle command, it also includes: after asynchronously feeding back the execution result of the vehicle command, determining whether the user repeatedly sends the same vehicle command, and if so, adjusting the type of the vehicle command to a synchronous type command.

[0041] Specifically, in order to further improve the user's driving experience, after the user receives asynchronous feedback, if it is detected that the user is dissatisfied with the feedback, the instruction library instructions that are the same as the vehicle instructions in the instruction library will be adjusted to synchronous type instructions. The specific detection method can be that after the user receives asynchronous feedback, the same vehicle instructions are repeatedly sent by voice or manually.

[0042] In some embodiments, Figure 2As shown, the speech recognition system 201 obtains speech data from the speech containing instructions issued by the user, converts the speech data into text through digital signal processing and natural language processing, and sends it to the speech processing system 202. The speech processing system 202 obtains the corresponding vehicle instruction by performing text semantic recognition and instruction parsing on the text. The speech processing system 202 determines whether the vehicle instruction is executable by querying the whole machine instruction library. If it is executable, the vehicle instruction is classified. If the vehicle instruction is a synchronous instruction, the synchronous instruction is sent to the speech execution system 203 through instruction issuance. The speech execution system 203 executes the synchronous instruction and obtains the execution result. If the execution result is failure, the synchronous instruction is repeatedly executed until it succeeds, or the execution result is still the same after the execution is repeated for 3 times. If the instruction fails, the voice execution system 203 reports the execution failure data to the execution failure reporting library and the instruction feedback system 204. The instruction feedback system sends the failed vehicle instruction and the reason for the execution failure to the speaker amplifier system 205 through voice conversion for voice broadcast. In some implementation processes, when the voice processing system 202 determines that the vehicle instruction is an asynchronous instruction, it is necessary to determine the success rate of instruction execution for the asynchronous instruction. When the execution success rate is greater than 50%, in the instruction feedback system 204, success feedback is performed and voice broadcast is performed through the speaker amplifier system 205. In other implementation processes, when the voice processing system 202 confirms that the vehicle instruction is not executable, the instruction feedback system 204 needs to perform unexecutable feedback and perform voice broadcast through the speaker amplifier system 205.
