Abstract:
A method of recognizing speech, comprising the steps of:a) inputting input voice data having a plurality of frames, each of said frames having a predetermined frame length;b) continuously generating a first frame signal for each of said frames, said first frame signal being indicative of a first feature of a corresponding one of said frames;c) continuously comparing said first frame signal to a predetermined set of standard signals and generating a similarity signal indicative of a degree of similarity between said first frame signal and one of said standard signals;d) continuously generating a second frame signal for each of said frames, said second frame signal being indicative of a second feature of a corresponding one of said frames;e) continuously cumulating said second frame signal corresponding to a predetermined combination from a set consisting of a beginning portion and an ending portion of said standard signals and said similarity signal over a plurality of said frames so as to generate a cumulative similarity signals; andf) recognizing said frames as speech based upon said cumulative similarity signal.
