Abstract

The present invention relates to a speech recognition device and method. The device includes: a communication part, which communicates with a user's mobile terminal; a noise filtering part, which acquires noise for a preset time after receiving an input of a speech recognition key, Then acquire the voice of the user, and remove the pattern noise in the voice by generating an anti-noise pattern signal capable of canceling the noise; and, the control unit controls the communication unit and the noise filtering unit to obtain and remove The speech after the pattern noise is sent to the speech recognition engine, so that the speech recognition engine learns speech information according to the user and performs speech recognition. The invention can ensure the safety and convenience of users during the driving process and can improve the voice acquisition rate and recognition rate.

Description

technical field [0001] The present invention relates to a voice recognition device and method, and in particular to a method for distinguishing users when acquiring voices for voice recognition and performing accumulation and learning of voice information by user. When acquiring voices, first stop the operation of noise sources and then detect surrounding patterns A voice recognition device and method that can improve the voice acquisition rate and recognition rate by removing the noise and removing it. Background technique [0002] Since the use of multimedia equipment (such as audio-visual navigation equipment) is now restricted during vehicle driving, the voice recognition function of vehicles is becoming more and more prominent. That is, the voice recognition technology is used on the vehicle to perform voice recognition so as to perform some functions that the vehicle can complete. [0003] However, in the case of performing speech recognition while the vehicle is runn...
