Abstract

A speech recognition system 7 for an automotive vehicle 10 is provided including a microphone receiver 12 for receiving a voice audio signal and converting the same to an analog signal 13, a microphone aimer for giving the microphone receiver 12 a locational bias for reception, an analog to digital converter 15 for converting the analog signal to a digital signal, a speech recognizer 17 for recognizing a voice from the digital signal received from the analog to digital converter 15, an occupant restraint system 22 having an occupant informational system 60/18 to control deployment of the occupant restraint system 22 resultant upon an occupant condition, an occupant restraint system signal generator 18 for signaling the occupant condition to the microphone aimer to locationally bias the reception of the microphone receiver 12.

Claims

1. A speech recognition system for an automotive vehicle comprising:

a microphone receiver for receiving a voice audio signal and converting the same to an analog signal;

a microphone aimer for giving said microphone receiver a locational bias for reception;

an analog to digital converter for converting said analog signal to a digital signal;

a speech recognizer for recognizing a voice from said digital signal received from said analog to digital converter;

an occupant restraint system having an occupant informational system to control deployment of said occupant restraint system resultant upon an occupant condition;

an occupant restraint system signal generator for signaling said occupant condition to said microphone aimer to locationally bias said reception of said microphone receiver.

2. A speech recognition system as described in claim 1, wherein the occupant condition is a position of said occupant in said vehicle.

3. A speech recognition system as described in claim 2, wherein said position of said occupant is at least partially determined based upon an adjusted position of a seat within said vehicle.

4. A speech recognition system as described in claim 3, wherein an electromagnetic sensor is utilized to determine a position of said occupant.

5. A speech recognition system as described in claim 4, having a plurality of sensors.

6. A speech recognition system as described in claim 2, wherein said position of said occupant is at least partially determined upon an adjusted position of a seat back within said vehicle.

7. A speech recognition system as described in claim 2, wherein a sonic sensor is utilized to determine a position of said occupant.

8. A speech recognition system as described in claim 7, having a plurality of sensors.

9. A speech recognition system as described in claim 2, wherein said position of said occupant is at least partially determined based upon a weight of said occupant on a seat within said vehicle.

10. A speech recognition system as described in claim 2, wherein said position of said occupant is at least partially determined based upon a pressure distribution of said occupant on a vehicle seat within said vehicle.

11. A speech recognition system for an automotive vehicle as described in claim 2, wherein said position of said occupant is at least partially determined based upon a pedal position of a positionally adjustable pedal assembly.

12. A speech recognition system for an automotive vehicle comprising:

a microphone receiver for receiving a voice audio signal and converting the same to an analog signal, said microphone receiver having an aimer employing dynamic and electronic adaptive beam forming;

an analog to digital converter for converting said analog signal to a digital signal;

a speech recognizer for recognizing a voice from said digital signals received from said analog to digital converter;

an occupant restraint system having an occupant informational system to control deployment of said occupant restraint system resultant upon seat occupant position, said occupant restraint system including sonic sensors to determine the position of said seat occupant within said vehicle; and

an occupant restraint system signal generator for signaling said occupant position to said microphone aimer to locationally bias said reception of said microphone.

13. A speech recognition system as described in claim 12, wherein said position of said seat occupant is at least partially determined by a position of said seat in respect to said vehicle.

14. A speech recognition system as described in claim 12, wherein said sensors sense a position of said seat occupant is at least partially determined by a weight of said seat occupant.

15. A speech recognition system as described in claim 12, wherein said sensors sense a position of said seat occupant is at least partially determined by sensing a pressure distribution of said seat occupant upon a seat of said vehicle.

16. A speech recognition system as described in claim 12, wherein said sensors sense a position of a seat occupant is at least partially determined by sonically sensing a position of said seat occupant within said vehicle.

17. A speech recognition system as described in claim 12, wherein said sensors sense a position of said seat occupant is at least partially determined by sensing a position of an adjustable pedal assembly.
