The voice processing module in the embodiment of the application is used for receiving the voice input of the user, processing the voice input, generating voice prompt information and sending the voice prompt information to the data configuration module 5. Specifically, the voice processing module may include a recording sub-module 2 and a screening sub-module 3, where the recording sub-module 2 is configured to record a voice input of a user, and the screening sub-module 3 provides a channel for screening a satisfactory voice for the user, for example, the voice input may be deleted or adjusted according to a selection input of the user, for example, a part of the content of the voice input may be intercepted, for example, only a few seconds of the voice input of one minute is selected, and the voice input may be accelerated, decelerated, and adjusted in pitch. When the voice input is processed by the user selection, the voice prompt information can be considered to be satisfied by the user. In some embodiments, the voice processing module may further include an audition sub-module 4 for playing the deleted or adjusted voice input, and the audition sub-module 4 may help the user to better judge whether the voice input has been processed to a satisfactory degree, so as to facilitate the user to confirm the voice prompt information of the heart instrument, for example, after the user adjusts the voice input in a home environment, the voice effect in a driving environment may be directly simulated, thereby effectively reducing the time required for configuration, and quickly achieving a satisfactory result for the user.

The data configuration module 5 in the embodiment of the present application is configured to receive preset state information input by a user, where the preset state information is used to represent a preset state of an automobile, for example, when the automobile is started, and when the automobile is backed, a speed of the automobile reaches a predetermined speed per hour, the preset state may be set. The data configuration module 5 is configured to bind the preset state information and the corresponding voice prompt information and send the bound preset state information and the corresponding voice prompt information to the multimedia control module 8 through the home gateway 6, so that the speaker 9 plays the voice prompt information when the automobile reaches the preset state. For example, in some embodiments, the user may set the preset state information as "back up", and the corresponding voice prompt information is selected as "please note whether there is a pedestrian behind"; the user can set the preset state information as 'automobile starting', and the corresponding voice prompt information is selected as 'please pay attention to fastening the safety belt', and the like.

In the embodiment of the present application, a method for configuring voice prompt information of an automobile is further provided, and the method may be executed in the terminal device, and the voice prompt information is configured through the system.

The methods set forth in the examples of the present application are explained and illustrated below in conjunction with the above description.

step 110, acquiring identity information of a user, and identifying the identity information;

in the embodiment of the application, before the voice prompt information is configured, it is first determined whether a person to be configured is a resident in a home environment, that is, a host of an automobile. The identification can be performed in various ways, for example, by RFID identification, iris identification, password input verification, and the like. Of course, the identification of the user identity information is not limited to the method set forth above, and the above-described manner is merely for illustration.

Step 120, when the identification information passes, acquiring voice input of a user, and processing the voice input to generate voice prompt information;

in the embodiment of the application, after the identity information of the user is identified, the user can be confirmed to be a family member, and the voice prompt information can be configured. At this time, the voice input of the user may be acquired, and a certain processing may be performed on the voice input, where the processing may be performed according to the selection input of the user, for example, the voice input may be deleted or adjusted. For example, a part of the content of the voice input may be intercepted, and the playing speed or the playing volume of the voice input may also be adjusted. When the voice input is processed by the user selection, the voice prompt information can be considered to be satisfied by the user. In some embodiments, the deleted or adjusted voice input can be played, so as to help the user to better judge whether the voice input is processed to a satisfactory degree, and the user can conveniently confirm the voice prompt information of the heart instrument.

Step 130, acquiring preset state information input by a user, and establishing a binding relationship between the preset state information and the voice prompt information;

and 140, sending the bound preset state information and the voice prompt information to a multimedia control module of the automobile, so that a loudspeaker of the automobile plays the voice prompt information when the automobile reaches a preset state.

In the embodiment of the application, as described above, when configuring the voice prompt information, the preset state information input by the user may be acquired, and the binding relationship between the preset state information and the voice prompt information is established, for example, in some embodiments, the user may set the preset state information as "backing up", and bind the corresponding voice prompt information "please note whether there is a pedestrian behind" and the preset state information "backing up"; in some embodiments, the user may further set the preset state information to "car start", and bind the corresponding voice prompt information "please pay attention to fastening the seat belt" and the preset state information "car start". And sending the bound preset state information and the bound voice prompt information to a multimedia control module of the automobile, so that a loudspeaker of the automobile plays the corresponding voice prompt information when the automobile reaches the preset state. It can be understood that, the configuration method in the embodiment of the application can greatly improve the flexibility of voice prompt information broadcasting, and the vehicle owner can set the configuration method by himself, so that the personalization is higher. Compared with the deadly fixed broadcast tone, the personalized sound can play a role in prompting, for example, parents can set the sound of children as voice prompt information, and thus, the driver can pay more attention to safety when driving.
