    Abstract: The main goal of this paper is to find some effective methods to improve the performance of speaker identification system. In speaker identification, we use wavelet transform to decompose the speech signals into several frequency bands and then use cepstral coefficients to capture the individualities of vocal track within the interested bands based on the acoustic characteristic of human ear. In addition, an adaptive wavelet-based filtering mechanism is applied to eliminate the small variation of wavelet coefficients caused by noise. In order to effectively utilize all these multi-band speech features, we propose a modified vector quantization method called multi-layer eigen-codebook vector quantization (MLECVQ) as the identifier. This model uses the multi-layer concept to eliminate the interference between the multi-band coefficients and then uses the principal component analysis (PCA) method to evaluate the codebooks for capturing more details of phoneme character. Experimental results show that the proposed method is better than the GMM+MFCC model on computational cost and recognition performance under clean and noisy speech data evaluations.
