An audible signal process method includes preparing, in at least one dictionary, a plurality of weighting factors each learned to optimize evaluation function established by a weighted learning audible signal and a target speech signal corresponding to the learning audible signal and used for weighting, estimating a noise component included in the input audible signal, calculating a feature quantity depending upon the noise component of the input audible signal, selecting a weighting factor corresponding to the feature quantity from the dictionary, and weighting the input audible signal using the selected weighting factor to generate a processed output audible signal. |
