Abstract

The invention provides a voice pick-up system and a voice pick-up method thereof. The voice pick-up system is characterized by comprising a controller, wherein a first microphone probe and a second microphone probe are electrically connected to the controller, and the controller is electrically connected with a vehicle speed sensor, an engine rotation speed sensor, an air conditioner wind speed sensor and a vehicle window state sensor through a CAN bus. The invention aims to provide the voice pick-up system in accordance with defects of the prior art, so that the voice recognition accuracy is effectively improved.

Description

technical field [0001] The invention belongs to the field of automobile electrical components, and in particular relates to a voice pickup system and a method thereof. Background technique [0002] At present, more and more car models have applied the voice recognition system, which is used for the driver to control the vehicle during driving. In order to be able to recognize the driver's instructions in the noisy environment in the car, the voice pickup system currently used in the vehicle uses an algorithm to reduce the noise of the obtained sound, which will lead to misjudgment of the driver's instructions in the absence of noise , ignoring the driver's part of the voice command which is less loud. Contents of the invention [0003] The object of the present invention is to provide a voice pick-up system aimed at the defects of the prior art, which can effectively improve the accuracy of voice recognition. [0004] The invention provides a voice pickup system, which i...
