Abstract

A speech recognition driven system provides a speech model based on a biometric signature. Initially, the speech recognition driven system receives a biometric signature from a user of the system. Based upon the received biometric signature, the system selects a speech model. The selected speech model is utilized to determine whether a voice input provided by the user corresponds to a speech selectable task that is recognized by the speech recognition driven system. When the voice input provided by the user corresponds to the speech selectable task, the system causes the speech selectable task to be performed. In one embodiment, the biometric signature is an image of the user'"'"'s face. When face recognition technology is implemented, the image of the user'"'"'s face is utilized to select a speech model.

Claims

1. A method for providing a speech model based on a biometric signature in a speech recognition driven system, comprising the steps of:

receiving a biometric signature from a user of the system;

selecting a speech model based on the received biometric signature;

utilizing the selected speech model to determine whether a voice input provided by the user corresponds to a speech selectable task that is recognized by the speech recognition driven system; and

performing a speech selectable task when the voice input provided by the user corresponds to a speech selectable task.

2. The method of claim 1, wherein the biometric signature is an image of the user'"'"'s face.

3. The method of claim 1, wherein the system utilizes a default speech model when the system fails to recognize the biometric signature.

4. The method of claim 1, wherein the system creates a new speech model when the system fails to recognize the biometric signature.

5. The method of claim 1, further including the step of:

updating the selected speech model such that the system adapts to the speech pattern of the user.

6. The method of claim 1, further including the step of:

prompting the user to provide another voice input when the voice input is not recognized.

7. The method of claim 1, wherein the speech selectable task is performed by a motor vehicle accessory.

8. A speech recognition driven system that utilizes selectable speech models, comprising:

a memory subsystem for storing information;

a processor coupled to the memory subsystem;

an audio input device coupled to the processor, the input device receiving a voice input from a user; and

speech recognition code for causing the processor to perform the steps of;

receiving a biometric signature from the user of the system;

selecting a speech model based on the received biometric signature;

utilizing the selected speech model to determine whether the voice input provided by the user corresponds to a speech selectable task that is recognized by the speech recognition driven system; and

performing a speech selectable task when the voice input provided by the user corresponds to a speech selectable task.

9. The system of claim 8, wherein the biometric signature is an image of the user'"'"'s face.

10. The system of claim 8, wherein the system utilizes a default speech model when the system fails to recognize the biometric signature.

11. The system of claim 8, wherein the system creates a new speech model when the system fails to recognize the biometric signature.

12. The system of claim 8, wherein the speech recognition code causes the processor to perform the additional steps of:

updating the selected speech model such that the system adapts to the speech pattern of the user.

13. The system of claim 8, wherein the speech recognition code causes the processor to perform the additional steps of:

prompting the user to provide another voice input when the voice input is not recognized.

14. The system of claim 8, further including:

an audio output device coupled to the processor, the output device providing voice feedback to the user.

15. The system of claim 14, wherein the audio output device is a speaker.

16. The system of claim 8, wherein the audio input device is a microphone.

17. The system of claim 8, wherein the speech selectable task is performed by a motor vehicle accessory.

18. A multi-level speech recognition driven system for controlling motor vehicle accessories that utilizes selectable speech models, comprising:

a memory subsystem for storing information;

a processor coupled to the memory subsystem;

a motor vehicle accessory coupled to the processor;

an audio input device coupled to the processor, the input device receiving a voice input from a user; and

speech recognition code for causing the processor to perform the steps of;

receiving a biometric signature from the user of the system;

selecting a speech model based on the received biometric signature;

utilizing the selected speech model to determine whether the voice input provided by the user corresponds to a speech selectable task that is recognized by the speech recognition driven system; and

controlling the motor vehicle accessory according to a speech selectable task when the voice input provided by the user corresponds to a speech selectable task.

19. The system of claim 18, wherein the biometric signature is an image of the user'"'"'s face.

20. The system of claim 18, wherein the system utilizes a default speech model when the system fails to recognize the biometric signature.

21. The system of claim 18, wherein the system creates a new speech model when the system fails to recognize the biometric signature.

22. The system of claim 18, wherein the speech recognition code causes the processor to perform the additional steps of:

updating the selected speech model such that the system adapts to the speech pattern of the user.

23. The system of claim 18, wherein the speech recognition code causes the processor to perform the additional steps of:

prompting the user to provide another voice input when the voice input is not recognized.

24. The system of claim 18, further including:

an audio output device coupled to the processor, the output device providing voice feedback to the user.

25. The system of claim 24, wherein the audio output device is a speaker.

26. The system of claim 18, wherein the audio input device is a microphone.
