Abstract
In at least one embodiment, a vehicle active noise cancellation (ANC) apparatus including an ANC controller is disclosed. The ANC controller is operably coupled to at least one error microphone. The ANC controller is configured to receive a first signal indicative of environmental noise that propagates through a vehicle cabin and that is received at a voice recognition (VR) microphone and to generate a noise cancellation wave to remove the environmental noise, the noise cancellation wave being received at the VR microphone. The ANC controller is configured to receive an audio output from the at least one error microphone that is at least indicative of the environmental noise and the noise cancellation wave received at the VR microphone and to apply at least one correction filter to the audio output to remove the environmental noise and the noise cancellation wave that is received at the VR microphone.
