Abstract

A first computing device registers a first grammar that is stored in a persistent memory of the first computing device and that is a system grammar of the first computing device. The first computing device further registers at least one second grammar associated with an application stored in at least one second computing device. Input including may be received. The first grammar is selected for the command upon a determination that the input is specified as a command in each of the first grammar and the second grammar.

Claims

1. A system, comprising a computer, the computer comprising a processor and a memory, wherein the computer is configured to:

receive input including at least one word;

determine that the input is specified as a command in a plurality of grammars, each of the two or more grammars being associated with a respective application in a plurality of applications;

select one of the applications to which to apply the command according a status of the application with respect to a human machine interface associated with the application; and

provide the command to the selected one of the applications.

2. The system of claim 1, wherein each of the applications is included on a computing device that is separate from the computer.

3. The system of claim 2, wherein the computer is further configured to select one of the computer and one of the separate devices to receive the command based on user input.

4. The system of claim 1, wherein the input is voice input.

5. The system of claim 1, wherein the computer is in a vehicle.

6. The system of claim 1, wherein the computer is further configured to register each of the plurality of application grammars, and further wherein registering an application grammar includes determining whether a command in the application grammar conflicts with a command in another grammar registered in the computer.

7. The system of claim 6, wherein the computer is further configured to reject a command included in an application grammar when the command in the application grammar is reserved by a system grammar.

8. A system, comprising a first computing device, the first computing device comprising a processor and a memory, wherein the first computing device is configured to:

register a first grammar that is stored in a persistent memory of the first computing device and that is a system grammar of the first computing device;

register at least one second grammar associated with an application stored in at least one second computing device;

receive input including at least one word;

select the first grammar for the command upon a determination that the input is specified as a command in each of the first grammar and the second grammar.

9. The system of claim 8, wherein the computing device is further configured to register a plurality of second grammars, each associated with an application stored in the at least one second computing device.

10. The system of claim 9, wherein registering each of the second grammars includes determining whether a command in the grammar being registered conflicts with a command in the first grammar or another second grammar registered in the first computing device.

11. The system of claim 9, wherein the computing device is further configured to

select one of the applications to which to apply the command according to a status of the application with respect to a human machine interface associated with the application;

and

provide the command to the selected one of the applications.

12. The system of claim 8, wherein the input is voice input.

13. The system of claim 8, wherein the computer is in a vehicle.

14. A method implemented in a computer, comprising:

receiving input including at least one word;

determining that the input is specified as a command in a plurality of grammars, each of the two or more grammars being associated with a respective application in a plurality of applications;

selecting one of the applications to which to apply the command according a status of the application with respect to a human machine interface associated with the application; and

providing the command to the selected one of the applications.

15. The method of claim 14, wherein each of the applications is included on a computing device that is separate from the computer.

16. The method of claim 15, wherein the computer is further configured to select one of the computer and one of the separate devices to receive the command based on user input.

17. The method of claim 14, wherein the input is voice input.

18. The method of claim 14 wherein the computer is in a vehicle.

19. The method of claim 14, further comprising registering each of the plurality of application grammars, wherein registering an application grammar includes determining whether a command in the application grammar conflicts with a command in another grammar registered in the computer.

20. The method of claim 19, further comprising rejecting a command included in an application grammar when the command in the application grammar is reserved by a system grammar.
