<p>PROBLEM TO BE SOLVED: To lessen the influence of the noises generated in a vehicle and to obtain higher recognition accuracy by detecting the state of noise elements which are the cause for the noises when the recognition accuracy is below a prescribed value and decreasing the noises by controlling the state of the detected noise elements. SOLUTION: An entire part processing section 1 has a navigation processing section 10, an agent processing section 11, etc. The agent processing section 11 judges whether the recognition accuracy of the speeches inputted from a microphone 265 is low or not by a speech control section 14 and if the accuracy is low, the processing section executes the control, such as adjustment, to a noise causative apparatus which is the cause for the noise. The agent processing section 11 executes the evaluation to the recognition result by a speech control section 14 of the speeches inputted from the microphone 26 and executes the judgment as to whether the recognition accuracy is low or not and the detection of the cause (opening or closing of a window, the operating state of an air conditioner or an audio operating state) of the noise to lower the recognition accuracy. The agent processing section 11 executes the noise removal processing for removing the noise cause.</p> |
