Abstract
Multiple similarities between phoneme feature data extracted from a word input signal and reference pattern data read out from a reference pattern memory are calculated by a similarity calculation section. The multiple similarities are converted by a conversion filter into posterior probabilities using parameter sets which are read out from a filter parameter bank in accordance with the obtained multiple similarities. The posterior probabilities are subjected to matching with data stored in word dictionary by a word matching section, thus discriminating the input word.
