PURPOSE: To recognize vocalization of voices simultaneously inputted to plural microphones by a voice recognition device. CONSTITUTION: This voice recognition device is provided with microphones 1-1 to 1-N converting an input voice to a voice signal, input voice analysis parts 2-1 to 2-N analyzing the voice signal from the microphones 1-1 to 1-N and converting to a characteristic vector system, characteristic vector system storage parts 3-1 to 3-N storing the characteristic vector system from the input voice analysis parts 2-1 to 2-N and a characteristic vector system monitor switch part 4 monitoring respective characteristic vector system storage parts 3-1 to 3-N and successively selecting and switching the storage part storing the effective characteristic vector system. Further, the device is provided with a recognition part 6 calculating the similarity between the effective vector system from respective storage parts and a standard pattern beforehand stored in a recognition dictionary part 5 and making the standard pattern that the similarity becomes maximum the recognition result of the input voice. |
