Abstract
Voice recognition is realized by a pattern matching with a voice pattern model, and when a large number of paraphrased words are required for one facility, such as a name of a hotel or a tourist facility, the pattern matching needs to be performed with the voice pattern models of all the paraphrased words, resulting in an enormous amount of calculation. Further, it is difficult to generate all the paraphrased words, and a large amount of labor is required. A voice recognition device includes: voice recognition means for applying the voice recognition to an input voice by using a language model and an acoustic model, and outputting a predetermined number of recognition results each including a set of a recognition score and a text representation; and N-best candidate rearrangement means for: comparing the recognition result to a morpheme dictionary held in a morpheme dictionary memory; checking whether a representation of the recognition result can be expressed by any one of combinations of the morphemes of the morpheme dictionaries; correcting the recognition score when the representation can be expressed; and rearranging an order according to the corrected recognition score so as to acquire recognition results.
