Patent ID: 6917910

Claim:
An apparatus for recognizing from texts comprising disfluency words and non-displuency words, said apparatus comprising: a first judging processor, wherein said first judging processor judges whether words inputted as an object of recognition are non-disfluency words; a second judging processor, wherein said second judging processor judges whether said inputted words constituting a condition necessary for recognizing said inputted words consist of only non-disfluency words, if said inputted words have been judged to be non-disfluency words by said first judging processor; a first probability calculator, wherein said first probability calculator calculates a probability, if said conditional words have been judged as containing non-disfluency words and disfluency words by said second judging processor, by using a dictionary containing a first language model which has been trained regarding disfluency words and non-disfluency words, and a second language model which has been trained regarding non-disfluency words and trained to ignore disfluency words so as to recognize words showing the highest probability of representing said inputted words; a second probability calculator, wherein said second probability calculator calculates said probability based on said first language model, if said object words have been judged as not being non-disfluency words by said first judging processor; and a third probability calculator, wherein said third probability calculator calculates said probability based on said second language model, if said conditional words have been judged as containing only non-disfluency words by said second judging processor.
