| Abstract: | In this paper,a fuzzy c-means（FCM） based Vector Quantization（VQ） approach is applied to the codebook of a voice recognition system,and then the isolated point detection method based on the sum of similarity coefficients is used to find out those isolated points.The experimental results show that the isolated point detection method can effectively exclude the interference of the outliers on the clustering results,and that the FCM based VQ technique reduces the quantization error remarkably.The recognition rate of VQ based voice recognition system can be improved by the proposed approach. |
