PROBLEM TO BE SOLVED: To conduct more accurate voice recognition by improving environmentally resisting performance. SOLUTION: A voice recognition device 10 for a vehicle is connected to a vehicle speed sensor 42, an engine controller 30, an air-conditioner controller 24, an audio device 26 or the like and has an acoustic pattern recognition section 50 which receives voice uttered by a person riding on the vehicle from a microphone and conducts voice recognition and an image pattern recognition section 54 which recognizes voice based on the image of the person's mouth photographed by a CCD camera 22. An environmental evaluation section 60 of the voice recognition device 10 for the vehicle selectively controls the voice recognition process of the acoustic pattern recognition section 50 and the voice recognition process of the image pattern recognition section 54 based on the vehicle conditions such as a vehicle speed, an air amount T of the air-conditioner, an audio volume A or the like.
