| Abstract: | In speech signal processing, the self adaptation vector quantization is widely used. The code training method of self adaptation vector quantization based on SFCM algorithm was proposed. The membership between training samples and codebook is readjusted and the least coding distortion is reached by the fuzzy clustering method. The codebook is more adapt to new speaker. The calculation of this method is simple. The coding average distortion is low. |
