Abstract(in English) This paper proposes a novel approach to recognize partial segments of utterance with high confidence instead of the complete utterance. The proposed method is based on a cooperative use of conventional n-gram constraints and additional grammatical constraints, applied to utterances considering insertions, deletions and substitutions. To apply the grammatical constraints efficiently, the constraints described by a context-free grammar are approximated in the form of a finite-state automaton. Through an experiment, it has been confirmed that the proposed method can recognize partial segments of an utterance with a higher reliability than conventional continuous speech recognition methods using only n-grams.
