Car driver voice assistant

Abstract

The invention provides a car driver voice assistant. The structure of the car driver voice assistant comprises an intelligent controller, and a pickup unit and an execution unit both connected with the intelligent controller; a voiceprint identification module, a voice command storage module and an instruction generation module are arranged in the intelligent controller; the instruction generation module is used for comparing a voice signal acquired by the pickup unit with voice commands pre-stored in the voice command storage module, and if finding out a voice command matched with the voice signal, controlling the execution unit to execute the operation corresponding to the voice command; the voiceprint identification module is used for performing voiceprint identification on the voice signal output by the pickup unit and controlling the enable end of the instruction generation module, and allowing the instruction generation module to output a signal only after determining that the voice signal is transmitted by the driver. The car driver voice assistant has the advantages that the identity of a speaker is identified by use of the voiceprint identification technology, a person other than the driver can be prevented from controlling the car by use of the voice command, the operation of the driver is simplified while the safety of driving is guaranteed, and the comfort of driving is improved.

Description

technical field [0001] The invention relates to a device capable of controlling a car through the driver's voice command, which belongs to the technical field of cars. Background technique [0002] In recent years, great breakthroughs have been made in speech recognition technology, and relatively mature commercialized voice assistants have appeared, such as Apple's Siri, Google's Google Now, and Microsoft's Cortana. In China, various voice assistants are also emerging, such as Smart 360, Xiaoi Robot, Wormhole and Lingxi, etc., which provide convenient conditions for human-computer interaction of various devices and devices. [0003] However, in cars, human-computer interaction is still achieved through knobs, buttons and touch screens, and the driver cannot directly issue various control commands in natural language. The main reason is that the existing voice recognition system cannot identify the identity of the speaker accurately enough, and cannot accurately distinguish...

[0003] However, in the car, human-computer interaction is still achieved through knobs, buttons and touch screens, and the driver cannot directly issue various control commands in natural language

The main reason is that the existing voice recognition system cannot identify the identity of the speaker accurately enough, and cannot accurately distinguish the voice signals sent by the driver and passengers. If the voice operation commands closely related to driving safety issued by passengers ( Such as acceleration, braking, etc.), the car control system will also execute, it is easy to cause traffic accidents, and pose a great threat to the safety of drivers, passengers and pedestrians, which is absolutely not allowed
