Abstract:

 In this paper, authors propose an auditory feature extraction algorithm in order to improve the performance of the 
speaker recognition system in noisy environments. In this auditory feature extraction algorithm, the Gammachirp filter bank is 
adapted to simulate the auditory model of human cochlea. In addition, the following three techniques are applied: cube-root 
compression method, Relative Spectral Filtering Technique (RASTA), and Cepstral Mean and Variance Normalization 
algorithm (CMVN).Subsequently, based on the theory of Gaussian Mixes Model-Universal Background Model (GMM-UBM), 
the simulated experiment was conducted. The experimental results implied that speaker recognition systems with the new 
auditory feature has better robustness and recognition performance compared to Mel-Frequency Cepstral Coefficients 
(MFCC), Relative Spectral-Perceptual Linear Predictive (RASTA-PLP),Cochlear Filter Cepstral Coefficients (CFCC) and 
gammatone Frequency Cepstral Coefficeints (GFCC).
