ABSTRACT:
A plurality of candidate phonetic segments extracted from the input speech signal are passed through transition networks prepared for the respective words so as to obtain a score by weighting/averaging the long-term strategic scores by taking consideration of statistic distribution of the similarities or distances of phonetic segments and the short-term strategic scores by taking consideration of the environment of the phonetic segments.
