In vector coding and decoding of LSP parameters of moving average type speech, it is structured that a vector of a spectrum corresponding to a stationary noise interval, or, further, a vector from which a mean vector found in advance is subtracted, is stored as one vector C0 in a vector codebook 14A, so that a spectrum corresponding to a silent interval or stationary noise can be outputted as one of code vectors. <IMAGE> |
