Aiming at the situation that the voice was vitiated by positive noise and the difference of pollutionextent between different parts of the voice,preserving the polluted parts of voice will bring in negative affectionto the confirmation system of speaker.This paper gives a method that based on normalized autocorrelation ro。bustness selection.Normalized autocorrelation not only shows the correlation of short—time voice frame,butalso shows the polluted extent of voice.As a result,we can wipe off the deeply polluted voice through the nor‘malized autocorrelation.Experiments showing,through the normalized autocorrelation wiping off the pollutedvoice,can improve confirmation ability of speaker in high noise environment.
