Abstract
A mirror-based audio system for a vehicle comprises an interior rearview mirror system including a plurality of microphones for receiving audio signals within a cabin of the vehicle. The plurality of microphones comprise at least two microphones which generate output signals indicative of sound generated within the vehicle cabin. The at least two microphones are (i) positioned within an interior rearview mirror assembly, (ii) positioned adjacent to an interior rearview mirror assembly, (iii) positioned in an attachment to an interior rearview mirror assembly, or (iv) positioned within a module mounted to the windshield. The audio system further includes a control which is operable to distinguish the presence of vocal signals versus non-vocal signals and to at least partially filter out the non-vocal signals.
