Description

Technical Field

[0001] The present invention relates to the technical field of automobile infotainment, and in particular to a voice control method for multiple audio media mounted on a vehicle. Background Art

[0002] With the continuous breakthroughs in voice technology, the basic voice capabilities have become stronger, and voice interaction can be called a "valuable tool". Specifically, it can support interruptions, multiple rounds of conversations, support context understanding, automatic error correction, support wake-up free, reduce false triggers and improve response speed. The improvement of these capabilities combines voice technology and in-vehicle systems into a good combination, which can provide drivers with a more convenient and safe way of interaction.

[0003] There may be multiple audio media in the vehicle system, and basic voice control of these audio media applications is also an urgent need of users. However, the general voice control method for multiple audio media in the vehicle has insufficient voice control capabilities, which increases the potential safety hazards caused by driver distraction. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a method for voice control of multiple audio media in a vehicle, which enhances the voice control capability, brings convenience to the driver and reduces potential safety hazards caused by distraction.

[0006] (II) Technical solution

[0007] To achieve the above object, the present invention provides the following technical solutions:

[0008] A method for voice control of multiple audio media in a vehicle comprises the following steps:

[0009] S1: monitors the status of multiple audio media applications;

[0010] S2: Determine the audio media that should respond to the control command in the current state according to the status of each audio media application;

[0011] When any change in the state of an audio media application is detected, the audio media application that should accept and process voice commands in the current scenario is determined based on the specific needs of the product in combination with the previously saved global state data of each audio media application, and the identification of this application is recorded. The decision plan for the audio media application that should accept and process voice commands in the current scenario includes:

[0012] Case 1: If there is no status data of other audio media applications globally, the currently monitored status application is used as the application that receives and processes voice commands;

[0013] In case 2, the state is switched to the foreground, and it is determined whether other audio media applications are in the playback state. If so, the application in the playback state continues to be used as the voice control application. If not, the application with this state change is used as the voice control application.

[0014] Case 3: The state is switched to the background, and the previous voice control application is maintained;

[0015] Case 4: The state switches to playing, and the application with this state change is used as a voice control application;

[0016] Case 5: The state is switched to pause. It is determined whether other audio media applications are in the playback state. If so, the application in the playback state is continued to be used as the voice control application. If not, the application with this state change is used as the voice control application.

[0017] S3: receiving a voice control start instruction input by a user;

[0018] S4: receiving voice information input by the user;

[0019] S5: generating a control instruction according to the voice information;

[0020] S6: Determine whether the audio medium is suitable for executing the control command. After obtaining the command, determine whether it is suitable for executing the command according to the application currently receiving and executing the voice command and its status. If it is not suitable for execution, generate prompt information according to the situation and then execute step 8. If it is suitable for execution, execute step 7.

[0021] If there is no globally identified audio application, a default application is selected as an application for determining whether it is suitable for execution;

[0022] If this application has no status or is paused, playback control can be performed;

[0023] If the application is in playback mode, you can perform pause control.

[0024] S7: execute control commands;

[0025] S8: Prompt the driver to the execution result;

[0026] S9: The recognition control process ends.

[0027] As a further solution of the present invention, the status of multiple audio media applications is monitored and saved in S1, including but not limited to foreground and background, pause, and play.

[0028] Furthermore, in S2, when a certain audio media state changes, the audio media that responds to voice control in the current state is determined based on the states of other monitored audio media.

[0029] On the basis of the above scheme, the control instruction sent by the user in S5 is judged against the calculated audio media state that needs to be responded to, and if the judgment is unsuccessful, no control is performed.

[0030] Furthermore, in S8, the user is prompted based on whether the control instruction is suitable for execution and the result of the execution.

[0031] (III) Beneficial effects

[0032] Compared with the prior art, the present invention provides a method for voice control of multiple audio media in a vehicle, which has the following beneficial effects:

[0033] 1. The present invention responds to the driver's control operation by voice broadcast or text display, which enhances the voice control capability, brings convenience to the driver and reduces potential safety hazards caused by distraction.

[0034] 2. The present invention monitors the status of each audio media application and determines the audio media application that should respond to the voice command after the status changes, thereby achieving control over multiple audio media and providing control accuracy and stability.

[0035] 3. The present invention is safe, efficient, highly intelligent and has a good market prospect. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Figure 1 The present invention is a flow chart of a method for voice control of multiple audio media in a vehicle. DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Reference Figure 1 , a method for voice control of multiple audio media in a vehicle, comprising the following steps:

[0039] S1: Monitor the status of multiple audio media applications. The vehicle system contains multiple audio media applications. It is necessary to monitor the status changes of each application after booting, including but not limited to foreground and background, play, pause, and globally save the status data of each application after the change;

[0040] S2: Determine the audio media that should respond to the control command in the current state according to the status of each audio media application;

[0041] When any change in the state of an audio media application is detected, the audio media application that should accept and process voice commands in the current scenario is determined based on the specific needs of the product in combination with the previously saved global state data of each audio media application, and the identification of this application is recorded. The decision plan for the audio media application that should accept and process voice commands in the current scenario includes:

[0042] Case 1: If there is no status data of other audio media applications globally, the currently monitored status application is used as the application that receives and processes voice commands;

[0043] In case 2, the state is switched to the foreground, and it is determined whether other audio media applications are in the playback state. If so, the application in the playback state continues to be used as the voice control application. If not, the application with this state change is used as the voice control application.

[0044] Case 3: The state is switched to the background, and the previous voice control application is maintained;

[0045] Case 4: The state switches to playing, and the application with this state change is used as a voice control application;

[0046] Case 5: The state is switched to pause. It is determined whether other audio media applications are in the playback state. If so, the application in the playback state is continued to be used as the voice control application. If not, the application with this state change is used as the voice control application.

[0047] This solution is simply described as focusing on the playback status. If nothing is playing, the audio media application that was last switched to the foreground is used as the voice control application.

[0048] S3: receiving a voice control start command input by a user. Specifically, the driver inputs the voice control start command by pressing a button in the vehicle or using a wake-up word, thereby activating the voice recognition function;

[0049] S4: receiving the voice information input by the user. Specifically, after activating the voice collection function in step 3, receiving the voice information input by the user, and determining the audio media application that should respond to the voice command after the state changes by monitoring the state of each audio media application, thereby realizing control of multiple audio media and providing control accuracy and stability;

[0050] S5: according to the control instructions generated by the voice information, the instructions of the driver's control intention are obtained through relevant voice technology according to the collected voice data;

[0051] S6: Determine whether the audio medium is suitable for executing the control command. After obtaining the command, determine whether it is suitable for executing the command according to the application currently receiving and executing the voice command and its status. If it is not suitable for execution, generate prompt information according to the situation and then execute step 8. If it is suitable for execution, execute step 7.

[0052] Here is a brief description of a solution to determine whether it is suitable for execution:

[0053] If there is no globally identified audio application, a default application is selected as an application for determining whether it is suitable for execution;

[0054] If this application has no status or is paused, playback control can be performed;

[0055] If the application is in playback mode, you can perform pause control.

[0056] The above is just a simple description of the judgment under two states. Other states can be defined according to product needs. Here we just explain the feasibility of the operation.

[0057] S7: Execute the control command, execute the control operation corresponding to the command on the audio application currently marked globally, and execute step 8 according to the operation situation or directly generate prompt information;

[0058] S8: Prompts the driver to the results of the operation and responds to the driver's control operation by voice broadcast or text display, which enhances the voice control ability, brings convenience to the driver and reduces potential safety hazards caused by distraction;

[0059] S9: The recognition control process ends.
