Method and device for quick voice login of intelligent vehicle

Abstract

The invention relates to a method and a device for quick voice login of an intelligent vehicle. The method comprises the following steps of simultaneously obtaining vocal print features and a device ID of an on-board host computer or a device ID of a mobile terminal, which is provided by a user, when the user logs in; affirming a storage unit in a cloud database according to the device ID of the on-board host computer or the device ID of a mobile terminal, which is provided by the user; when the device ID is affirmed to be in the storage unit of the cloud database, carrying out matching and retrieval on the extracted vocal print features in the storage unit; and when the vocal print features are matched successfully, logging in successfully, otherwise failing to log in. The user information is classified and stored through the device ID, so that the time for matching and retrieval of the vocal print features is greatly reduced, and the login is realized through the vocal print features of the user while a username and a login password cannot be input, so that the login safety of vehicle-mounted terminals, such as an electronic control unit, is increased, the user login is greatly facilitated, and meanwhile, the user identity can be quickly identified to realize the quick login.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a method and device for fast voice login of smart cars. Background technique [0002] With the continuous development of automobile technology, today's automobiles are becoming more and more energy-saving, environmentally friendly and intelligently interconnected, and the functions in the automobile are becoming more and more complex. In order to better manage these functions and facilitate interaction with the driver, a car terminal such as a trip computer is usually installed in the car. The login of vehicle-mounted terminals such as trip computer is usually input through control keys or touch screen. [0003] In the prior art, user verification is mainly performed through user name and login password. In some implementation solutions, the input of the control instruction is also implemented through speech recognition. The current voice recognition control command scheme ...

AI Technical Summary

Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the following problems existed in the prior art, the verification and login through the user name and login password are prone to forgetting the password, leakage of the user name and login password, etc.

In the existing method of voice control of vehicle-mounted terminals, voice control command data is stored and called based on a voice database, resulting in a huge system, slow update speed, high cost, and low system flexibility. Due to the continuous increase in the number of registered car users , the stored user data is very large, and the existing speech recognition scheme takes a long time to identify the user's identity based on the user's pronunciation characteristics in a short time
