Improved speech recognition algorithm based on MFCC feature

YUAN Zheng-wu1,2,XIAO Wang-hui11.Sino-Korea GIS Research Center,Chongqing University of Posts & Telecommunications,Chongqing 400065,China 2.Civil Engineering Mobile Station for Post Doctors,Chongqing University,Chongqing 400045,China  
Aiming at low calculation accuracy of MFCC feature parameters for speech recognition in high-frequency signals,this paper adopts the combination algorithm of IMFCC,MIDMFCC,MFCC,which uses a mixture of filter banks to enhance high-frequency calculation accuracy in the calculation accuracy.The experiments result shows that the recognition rate of improved algorithm increases compared to the classical algorithm in the same environment.
