Abstract：
 A vector quantization method includes framing inputted voice signal sample point to form a super frame, picking up A sound channel parameter as well as voiceless and voiced consonant parameter for quantization, converting A sound channel parameter to be line spectrum pair parameter, deducting DC subcomponent, confirming line spectrum pair predictive value, using line spectrum pair parameter without DC to detuct the prodictive value for carrying out vector quantization.
