ABSTRACT:
A speech recognizing device. Natural speech recognizing means recognizes speech input in an application program by dictation. Recognition result converting means converts a recognition result from said natural speech recognizing means into a final recognition result processable by said application program on the basis of a grammar to he used for recognizing said input speech in a grammar method. The recognition result converting means further comprises candidate sentence generating means for evolving said grammar to generate candidate sentences that are candidates for said final recognition result: and matching means for selecting a candidate sentence as said final recognition result among the candidate sentences by matching said candidate sentences generated by said candidate sentence generating means against the recognition result by said natural speech recognizing means. The candidate sentence comprises a sentence having an associated highest score calculated according to the formula “(ngramWords−replacedWords−rejectedWords−insertedWords)
gramWords.”
