Abstract

A speech recognition system is provided. The speech recognition system includes a speech recognition module; a plurality of domain specific dialog manager modules that communicate with the speech recognition module to perform speech recognition; and a speech interface module that that communicates with the plurality of domain specific dialog manager modules to selectively enable the speech recognition.

Claims

1. A speech recognition system, comprising:

a speech recognition module;

a plurality of domain specific dialog manager modules that communicate with the speech recognition module to perform speech recognition; and

a speech interface module that communicates with the plurality of domain specific dialog manager modules to selectively enable the speech recognition.

2. The system of claim 1 further comprising a human machine interface (HMI) module that communicates with the speech interface module based on user input.

3. The system of claim 2 wherein the speech interface module communicates speech recognition results to the HMI module.

4. The system of claim 3 wherein the domain specific dialog manager modules communicate the speech recognition results to the speech interface module.

5. The system of claim 1 wherein the plurality of domain specific dialog manager modules each include domain specific control logic.

6. The system of claim 5 wherein the domain specific control logic includes at least one of display logic, error logic, and speech recognition logic.

7. The system of claim 1 wherein the plurality of domain specific dialog manager modules include at least one grammar.

8. The system of claim 1 wherein the plurality of domain specific dialog manager modules include a language model.

9. The system of claim 1 wherein the plurality of domain specific dialog manager modules includes at least one of a phone dialog manager module, a navigation dialog manager module, a media dialog manager module, a telematics dialog manager module.

10. The system of claim 1 wherein at least one of the plurality of domain specific dialog manager modules includes a network interface manager module.

11. A vehicle, comprising:

a plurality of speech enabled applications; and

a speech recognition system that communicates with each of the plurality of speech enabled applications to perform speech recognition.

12. The vehicle of claim 11 wherein the speech recognition system includes a plurality of domain specific dialog manager modules that are each associated with at least one of the plurality of speech enabled applications.

13. The vehicle of claim 12 wherein the speech recognition system further includes a speech interface module that that communicates with the plurality of domain specific dialog manager modules to selectively enable the speech recognition.

14. The vehicle of claim 13 wherein the speech recognition system further includes a human machine interface (HMI) module that communicates with the speech interface module based on user input.

15. The vehicle of claim 12 wherein the plurality of domain specific dialog manager modules each include domain specific control logic.

16. The vehicle of claim 15 wherein the domain specific control logic includes at least one of display logic, error logic, and speech recognition logic.

17. The vehicle of claim 12 wherein the plurality of domain specific dialog manager modules include at least one grammar.

18. The vehicle of claim 12 wherein the plurality of domain specific dialog manager modules include a language model.

19. The vehicle of claim 12 wherein the plurality of domain specific dialog manager modules includes at least one of a phone dialog manager module, a navigation dialog manager module, a media dialog manager module, a telematics dialog manager module.

20. The vehicle of claim 12 wherein at least one of the plurality of domain specific dialog manager modules includes a network interface manager module.
