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:

register each of a 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;

receive input including at least one word;

determine that the input is specified as a command in a plurality of the grammars, each of the grammars being associated with a respective instance of one application in a plurality of instances of the application each currently running on one of a plurality of devices;

select one of the currently-running instances of the application to which to apply the command according a specified status of the selected instance of the application; and

provide the command to the selected one of the applications.

2. The system of claim 1, wherein each of the plurality of devices is 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 reject a command included in an application grammar when the command in the application grammar is reserved by a system grammar.

7. The system of claim 1, wherein the computer is further configured to specify the status based on a device associated with the currently-running instance.

8. A method implemented in a computer, comprising:

registering each of a 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;

receiving input including at least one word;

determining that the input is specified as a command in a plurality of the grammars, each of the grammars being associated with a respective instance of one application in a plurality of instances of the application each currently running on one of a plurality of devices;

selecting one of the currently-running instances of the application to which to apply the command according a specified status of the selected instance of the application; and

providing the command to the selected one of the applications.

9. The method of claim 8, wherein each of the plurality of devices is a computing device that is separate from the computer.

10. The method of claim 9, 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.

11. The method of claim 8, wherein the input is voice input.

12. The method of claim 8, wherein the computer is in a vehicle.

13. The method of claim 8, further comprising rejecting a command included in an application grammar when the command in the application grammar is reserved by a system grammar.

14. The method of claim 8, wherein the status is specified based on a device associated with the currently-running instance.
