ABSTRACT:
There is provided a voice recognition system comprising a standard pattern memory in which a voice pattern of a predetermined word is stored as a positive reference pattern and also voice patterns of words similar to but different from the first-mentioned word are stored as negative reference patterns, a pattern comparator for calculating dissimilarities of an input voice pattern with respect to the positive reference pattern and negative reference patterns, and a discriminator for providing a coincidence confirmation output signal when the dissimilarity with respect to the positive reference pattern is less than a predetermined threshold value and less than the dissimilarities with respect to the negative reference patterns while otherwise rejecting the result of recognition.
