Abstract

A voice acquisition system for a vehicle includes an interior rearview mirror assembly attached at an inner portion of the windshield of a vehicle equipped with the interior rearview mirror assembly. The interior rearview mirror assembly includes at least two microphones for receiving audio signals within a cabin of the vehicle and generating an output indicative of the audio signals. A control is in the vehicle and is responsive to the output from the at least one microphone. The control at least partially distinguishes vocal signals from non-vocal signals present in the output. The at least two microphones provide sound capture for at least one of a hands free cell phone system, an audio recording system and a wireless communication system.

Claims (35)

1. A voice acquisition system for a vehicle, said voice acquisition system comprising:

wherein said at least two microphones provide sound capture for at least one of a hands free cell phone system, an audio recording system and a wireless communication system.

2. The voice acquisition system of claim 1 , wherein said control is operable to distinguish said vocal signals present in said output from said non-vocal signals by a ratio of at least 10:1.

3. The voice acquisition system of claim 1 , wherein at least one of (a) said voice acquisition system comprises an indicator operable to indicate when said vocal signals are being adequately distinguished by said control, (b) said control is disposed within a mirror housing of said interior rearview mirror assembly, and (c) said interior rearview mirror assembly includes at least one user input for controlling at least one accessory of the equipped vehicle.

4. The voice acquisition system of claim 1 , wherein said interior rearview mirror assembly comprises an interior electrochromic rearview mirror assembly having electrically variable reflectivity, and wherein said interior electrochromic rearview mirror assembly includes electronic circuitry for at least adjusting the reflectivity of said interior electrochromic rearview mirror assembly, and wherein said at least two microphones at least one of (a) accesses a component of said electronic circuitry of said interior electrochromic rearview mirror assembly, and (b) shares a component of said electronic circuitry of said interior electrochromic rearview mirror assembly.

5. The voice acquisition system of claim 1 including an illumination source for a vehicle security system, wherein said illumination source for a vehicle security system is one of (i) included in said interior rearview mirror assembly of the equipped vehicle, (ii) positioned adjacent to said interior rearview mirror assembly of the equipped vehicle, and (iii) included in an attachment to said interior rearview mirror assembly of the equipped vehicle.

6. The voice acquisition system of claim 1 , wherein said voice acquisition system is operable to communicate with devices or components in the equipped vehicle via a signal carried over a vehicle bus network of the equipped vehicle.

7. The voice acquisition system of claim 1 , wherein at least two of (a) said non-vocal signals originate from at least one noise source selected from the group consisting of engine noise, road noise, wind noise, HVAC noise, a radio and a turn signal, (b) said non-vocal signals originate from at least one noise source selected from the group consisting of wind noise, a radio and HVAC noise, said voice acquisition system being operable to automatically adjust at least one of (i) a window setting, (ii) a radio volume and (iii) a fan speed of a blower in response to said noise, (c) said at least two microphones provides sound capture for a hands free cell phone system, (d) said at least two microphones provides sound capture for an audio recording system, and (e) said at least two microphones provides sound capture for a wireless communication system.

8. A voice acquisition system for a vehicle, said voice acquisition system comprising:

an interior rearview mirror assembly attached at an inner portion of the windshield of a vehicle equipped with said interior rearview mirror assembly;

said interior rearview mirror assembly including at least two microphones for receiving audio signals within a cabin of the equipped vehicle and generating an output indicative of said audio signals, wherein said at least two microphones generate outputs indicative of sound generated within the vehicle cabin;

a control in the vehicle, said control responsive to said output from said at least two microphones, said control at least partially distinguishing vocal signals from non-vocal signals present in said output, wherein said control is operable to distinguish said vocal signals present in said output from said non-vocal signals by a ratio of at least 10:1; and

wherein said at least two microphones provide sound capture for at least one of a hands free cell phone system, an audio recording system and a wireless communication system.

9. The voice acquisition system of claim 8 , wherein at least one of (a) said voice acquisition system comprises an indicator operable to indicate when said vocal signals are being adequately distinguished by said control, (b) said control is disposed within a mirror housing of said interior rearview mirror assembly, and (c) said interior rearview mirror assembly includes at least one user input for controlling at least one accessory of the equipped vehicle.

10. The voice acquisition system of claim 8 , wherein said interior rearview mirror assembly comprises an interior electrochromic rearview mirror assembly having electrically variable reflectivity, and wherein said interior electrochromic rearview mirror assembly includes electronic circuitry for at least adjusting the reflectivity of said interior electrochromic rearview mirror assembly, and wherein said at least two microphones at least one of (a) accesses a component of said electronic circuitry of said interior electrochromic rearview mirror assembly, and (b) shares a component of said electronic circuitry of said interior electrochromic rearview mirror assembly.

11. The voice acquisition system of claim 8 including an illumination source for a vehicle security system, and wherein said illumination source for a vehicle security system is one of (i) included in said interior rearview mirror assembly of the equipped vehicle, (ii) positioned adjacent to said interior rearview mirror assembly of the equipped vehicle, and (iii) included in an attachment to said interior rearview mirror assembly of the equipped vehicle.
