1. A boundary estimation method of speech recognition comprising the steps of:

  • (a) analyzing an input speech sample to extract a time window of speech parameters.(b) calculating a first probability that a phonetic boundary of the input speech exists at a center of the time window;

    (c) calculating a second probability that the phonetic boundary of the input speech does not exist at the center of the time window; and

    (d) calculating a value indicative of the likelihood that the phonetic boundary of the speech exists at the center of the time window on the basis of the first probability and the second probability.
