Voice command acquisition system and method
First Claim
1. A voice command acquisition method for motor vehicles, which comprises the following steps:
- receiving an input signal containing a useful voice component and a noise component;
querying an electronic system of the motor vehicle for one or more possible sources of the noise component and classifying the noise component as one of a plurality of characteristic noise components;
eliminating or reducing an intensity of the noise component by actively controlling the source of the noise component; and
subsequently continuing with the voice command acquisition.

Abstract
A voice command acquisition method and system for motor vehicles is improved in that noise source information is obtained directly from the vehicle system bus. Upon receiving an input signal with a voice command, the system bus is queried for one or more possible sources of a noise component in the input signal. In addition to vehicle-internal information (e.g., window status, fan blower speed, vehicle speed), the system may acquire external information (e.g., weather status) in order to better classify the noise component in the input signal. If the noise source is found to be a window, for example, the driver may be prompted to close the window. In addition, if the fan blower is at a high speed level, it may be slowed down automatically.

7. A voice command acquisition system in a motor vehicle, which comprises the following steps:
-
a microphone disposed to capture a voice command uttered by an occupant of the motor vehicle; a processor connected to a system bus of the motor vehicle and to said microphone for receiving a microphone capture signal containing the voice command and a noise component; said processor being programmed to; query the system bus for a status of possible noise sources in the microphone capture signal; issue a command triggering the noise source to be eliminated or alleviated for improving a success rate of a voice recognition; and prompt for a continuance of the voice command acquisition and recognition. - View Dependent Claims (8)
