Abstract

A method, system and article of manufacture of recognizing a voice command. One embodiment of the invention comprises: receiving a voice input; using the number of sound fragments, determining a number of sound fragments to be processed in a first set of sound fragments; determining whether the first set of sound fragments of the voice input matches with the first set of sound fragments of a voice command; and if the first set of sound fragments matches with the first set of sound fragments of the voice command, then determining whether one or more remaining sound fragments matches with one or more remaining sound fragments of the voice command.

Claims

1. A method of recognizing a voice command, comprising:

receiving a voice input;

determining a number of sound fragments to be processed in a first set of sound fragments of the voice input;

using the number of sound fragments, determining whether the first set of sound fragments from the voice input matches with a first set of sound fragments of a voice command; and

if the first set of sound fragments matches with the first set of sound fragments of the voice command, then determining whether one or more remaining sound fragments matches with one or more remaining sound fragments of the voice command.

2. The method of claim 1, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system.

3. The method of claim 1, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

and wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system.

4. The method of claim 1, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system; and

wherein the number of sound fragments of the voice input depends on a load of the first processing system and a load of the second processing system.

5. The method of claim 1, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system; and

wherein determining the number of sound fragments to be processed in the first set of sound fragments comprises;

monitoring a load of the first processing system and a load of the second processing system; and

determining the number of sound fragments of the voice input based on the load of the first processing system and the load of the second processing system, wherein the number of sound fragments of the voice input is reduced when the load of the first processing system exceeds a predefined threshold.

6. The method of claim 1, further comprising if the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command, then invoking an action for which the voice command is configured.

7. The method of claim 1, further comprising if the one or more remaining sound fragments does not match with the one or more remaining sound fragments of the voice command, then discarding the voice input.

8. The method of claim 1, further comprising if the first set of sound fragments does not match with the first set of sound fragments of the voice command, then discarding the voice input and processing a subsequent voice input.

9. A method of recognizing a voice command, comprising:

receiving a voice input;

determining, by a load manager, a number of sound fragments to be processed in a first set of sound fragments of the voice input;

using the number of sound fragments of the voice input, determining, by a first processing system, whether the first set of sound fragments of the voice input matches with a first set of sound fragments of a voice command; and

if the first set of sound fragments matches with the first set of sound fragments of the voice command, then determining, by a second processing system, whether one or more remaining sound fragments matches with one or more remaining sound fragments of the voice command.

10. The method of claim 9, wherein the number of sound fragments depends on a load of the first processing system and a load of the second processing system.

11. A computer readable medium containing a program which, when executed, performs an operation, comprising:

receiving a voice input;

determining a number of sound fragments to be processed in a first set of sound fragments of the voice input;

using the number of sound fragments, determining whether the first set of sound fragments of the voice input matches with the a set of sound fragments of a voice command; and

if the first set of sound fragments matches with the first set of sound fragments of the voice command, then determining whether one or more remaining sound fragments matches with one or more remaining sound fragments of the voice command.

12. The computer readable medium of claim 11, determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system.

13. The computer readable medium of claim 11, wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system.

14. The computer readable medium of claim 11, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

and wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system.

15. The computer readable medium of claim 11, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system; and

wherein the number of sound fragments depends on a load of the first processing system and a load of the second processing system.

16. The computer readable medium of claim 11, wherein determining whether the first set of sound fragments matches with the first set of sound fragments of the voice command is performed by a first processing system;

wherein determining whether the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command is performed by a second processing system; and

wherein determining the number of sound fragments to be processed in the first set of sound fragments comprises;

monitoring a load of the first processing system and a load of the second processing system; and

determining the number of sound fragments based on the load of the first processing system and the load of the second processing system, wherein the number of sound fragments is reduced when the load of the first processing system exceeds a predefined threshold.

17. The computer readable medium of claim 11, wherein the operation further comprises if the one or more remaining sound fragments matches with the one or more remaining sound fragments of the voice command, then invoking an action for which the voice command is configured.

18. The computer readable medium of claim 11, wherein the operation further comprises if the one or more remaining sound fragments does not match with the one or more remaining sound fragments of the voice command, then discarding the voice input.

19. The computer readable medium of claim 11, wherein the operation further comprises if the first set of sound fragments does not match with the first set of sound fragments of the voice command, then discarding the voice input and processing a subsequent voice input.

20. A computer readable medium containing a program which, when executed, performs an operation, comprising:
