Characteristic varibles of waveform vector quantizer of speech signal are presented and used to analyze codebook and its training sequence. It includes three parts, i. e., constructing initial codebook efficiently, training codebook fast and quantizing input vectors fast. Computer simulations show that the training speed of codebook is quickened by the new design algorithm and the complexity of vector quantizer is reduced.
