Abstract
A voice acquisition system for a vehicle includes a rearview mirror assembly, at least one microphone and a control. The at least one microphone receives audio signals within a cabin of the vehicle and generates an output signal indicative of the audio signals. The at least one microphone provides sound capture for at least one of a hands free cell phone system, an audio recording system and an emergency communication system. The control is operable to receive the output signal from the at least one microphone, and is operable to distinguish the presence of vocal signals from non-vocal signals. The control distinguishes the vocal signals from the non-vocal signals by a ratio of at least 2:1.
