A code conversion table, in which a code of a voice with noise added thereto and a code of a voice without noise are associated with each other in terms of probability, is referred to in a code converter. Using the code converter, a code is obtained in a vector quantizer by vector-quantizing cepstrum coefficients extracted from the voice with noise added thereto, and is converted into a code of a voice obtained by suppressing the noise in the voice with noise added thereto. Linear predictive coefficients are obtained from the code, and the voice signal is reproduced in a synthesis filter according to the linear predictive coefficients.
