<p>PROBLEM TO BE SOLVED: To reduce erroneous recognition among keywords.SOLUTION: A voice recognition device (1) includes: a similarity word database (DB) (203) for pre-storing similarity word information related to keywords mutually similar acoustically; a determination part (106) for referring to the similarity word information to determine whether there is a second word similar to a first word estimated by a first recognition process part (100); an extraction part (108) for extracting a partial voice signal in a specific section predetermined from a voice signal if determined that there is the second word; and a second recognition part (110) that includes a determination part (114) for performing determination processing in which a keyword having a higher degree of likelihood between the first and second words is regarded as a recognition result, on the basis of: a feature amount of the partial voice signal; and a second model parameter (202) corresponding to the respective specific sections of the first and second words.</p> |
