Abstract

Methods and systems are provided for processing speech for an autonomous or semi-autonomous vehicle. In one embodiment, a method includes receiving, by a processor, context data generated by the vehicle; determining, by a processor, a dialog delivery method based on the context data; and selectively generating, by a processor, a dialog prompt to the user via at least one output device based on the dialog delivery method.

Claims

1. A method of processing speech for an autonomous or semi-autonomous vehicle, comprising:

receiving, by a processor, context data generated by the vehicle;

determining, by a processor, a dialog delivery method based on the context data; and

selectively generating, by a processor, a dialog prompt to the user via at least one output device based on the dialog delivery method.

2. The method of claim 1, wherein the context data includes at least one of a level or mode of automation of the vehicle, a vehicle state, road conditions, and a driver state.

3. The method of claim 1, wherein the delivery method includes a dialog pace.

4. The method of claim 3, wherein the dialog pace includes one or more time periods associated with at least one of speech recognition and speech prompt delivery.

5. The method of claim 3, wherein the delivery method at least one of increases, decreases, or delays a dialog pace.

6. The method of claim 1, wherein the delivery method includes an indication of an input modality.

7. The method of claim 6, wherein the input modality is associated with at least one of a microphone, a touch screen, an image processor, a knob, and a switch.

8. The method of claim 1, wherein the delivery method includes an indication of an output modality.

9. The method of claim 8, wherein the output modality is associated with the at least one output device, and wherein the output device includes at least one of an audio device, a visual device, and a haptic device.

10. The method of claim 1, further comprising determining the dialog prompt based on the context data.

11. A system for processing speech for an autonomous or semi-autonomous vehicle, comprising:

a non-transitory computer readable medium comprising;

a first module that receives, by a processor, context data generated by the vehicle;

a second module that determines, by a processor, a dialog delivery method based on the context data; and

a third module that selectively generates, by a processor, a dialog prompt to the user via at least one output device based on the dialog delivery method.

12. The system of claim 11, wherein the context data includes at least one of a level or mode of automation of the vehicle, a vehicle state, road conditions, and a driver state.

13. The system of claim 11, wherein the delivery method includes a dialog pace.

14. The system of claim 13, wherein the dialog pace includes one or more time periods associated with at least one of speech recognition and speech prompt delivery.

15. The system of claim 11, wherein the delivery method at least one of increases, decreases, or delays a dialog pace.

16. The system of claim 11, wherein the delivery method includes an indication of an input modality.

17. The system of claim 16, wherein the input modality is associated with at least one of a microphone, a touch screen, an image processor, a knob, and a switch.

18. The system of claim 11, wherein the delivery method includes an indication of an output modality.

19. The system of claim 18, wherein the output modality is associated with the at least one output device, and wherein the at least one output device includes at least one of an audio device, a visual device, and a haptic device.

20. The system of claim 11, further comprising determining the dialog prompt based on the context data.
