PROBLEM TO BE SOLVED: To provide a voice recognition device with high correct answer accuracy. SOLUTION: The voice recognition device comprises: a voice recognition section including at least two model dependence voice recognition sections for performing voice recognition on an input utterance by using at least one language model or a sound model, and outputting a result; an utterance correlation evaluation section for calculating correlation of the recognition result included in multiple model dependence recognition results; a word chain validity determination section for calculating validity of chain of words included in multiple models dependence recognition result; and a recognition result selection section for selecting an optimum voice recognition result from multiple models dependence recognition result, based on the results of the utterance correlation evaluation section and the word chain validity determination section.
