METHOD OF REDUCING HEATING VENTILATING AND AIR CONDITIONING NOISE USING HEATING VENTILATING AND AIR CONDITIONING INFORMATION AND THE APPARATUS USING THEREOF

摘要

A method and a device for reducing the coordination noise using the coordination information are provided to remove the coordination noise included in a speech signal by loading a DLL file according to the coordination information. A method for reducing the coordination noise using the coordination information is as follows. A DLL file including a noise filter coefficient is generated(S300) in order to reduce the coordination noise generated relative to the intensity of the conditioning mode of vehicles. The compatibility of the noise filter currently applied is determined based on the presently input coordination information, once the current coordination information of the vehicle and a PTT(Push-to-Talk) signal to start the voice recognition are input(S301,S302). The DLL file is loaded to the noise filter according to the input current coordination information, if the presently applied noise filter is not suitable(S303,S304). The inputted speech signal applies the noise filter coefficient of the DLL file to the noise filter in order to be filtered(S305).
