step S10: acquiring voice information, and acquiring a target information template matched with the voice information according to a preset information template library; the information template library comprises at least one pre-created information template.
The voice information acquisition process comprises the steps that firstly, a voice interaction process is carried out, a user can awaken a voice acquisition module through a voice keyword, then the user inputs an operation to be executed through voice, and after the voice signal is acquired, the voice signal is converted into at least one intermediate parameter comprising characters, pictures and videos, so that actual control content contained in the voice signal is acquired. It should be noted that the voice information may be output by an in-vehicle person including a driver or other in-vehicle persons, for example, the driver may ask other in-vehicle passengers to select a destination, and a rear-row in-vehicle person may input a voice through the voice obtaining module.
It can be understood that the preset information template library includes at least one pre-created information template, and after the voice obtaining module obtains the controlled voice content, the preset information template library needs to be matched with a plurality of information templates in the pre-created information template library one by one to determine a target information template finally suitable for the voice content.
It can be understood that the voice obtaining module can obtain multiple rounds of voice information, and combine the voice information according to the information templates corresponding to the multiple rounds of voice information to determine a final target information template. The voice acquisition module is used for determining a first information template according to the first round of voice information and the preset information template base, determining a second information template according to the second round of voice information and the preset information template base when the user inputs a second round of voice again, and combining and generating a corresponding final target information template according to the first information template and the second information template. It should be noted that the voice information may be input for multiple times within a preset time, for example, the preset time is 30S, the driver continuously inputs two pieces of information and the voice information within 30S, matches two pieces of information templates after acquiring the two pieces of voice information, and finally determines the final target information template according to the two pieces of information templates, where it is to be noted that the multiple pieces of voice information may be respectively from voices of different people in the vehicle, and this is not limited herein.
