PROBLEM TO BE SOLVED: To drastically reduce a rate of a malfunction by discarding utterance when the utterance which is not assumed by a device is outputted, in various information devices including a speech recognition system.;SOLUTION: In various information processing devices 1 including a speech recognition system, a language model learning means 10 creates a language model 7 by modeling a sentence which is not assumed by the information processing device 1, and a speech recognition dictionary creation device 11 creates a speech recognition dictionary 8 which registers a word that is not assumed. When a speech recognition means 3 performs speech recognition on human utterance which is inputted by a speech input means 2 by using the language model 7, the speech recognition dictionary 8 and a sound model 9, since a tag (label) is attached to a voice recognition result 6 for indicating that a word is not assumed by the various information processing devices 1, a malfunction in an output means 5 is prevented by automatically discarding utterance which is not assumed by the information processing device 1 in a processing means 4.;COPYRIGHT: (C)2011,JPO&INPIT
