Abstract: Considering the sharp decline in the recognition accuracy of MFCC characteristic parameter for speaker recog} nition in low SNR environments, this paper proposed TEC}CFCC characteristic parameter extraction method. Signal phase matching is applied to eliminate speech noise on the basis of CFCC characteristic parameter, and then teager energy operator is added to the acquisition of CFCC characteristic parameter. In this way TEC}CFCC characteristic parameter is obtained and the energy of speech becomes one of the characteristic parameters for speaker recognition. Experiment results show that the recognition accuracy can reach to 83. 2 0 o in a一5dI3 SNR of vehicle interior noise environment by using TEC)-CFCC characteristic parameter.
