Abstract

An embodiment provides a method, including: receiving, at an audio receiver of an information handling device, user voice input; identifying, using a processor, words included in the user voice input; determining, using the processor, one of the identified words renders ambiguous a command included in the user voice input; accessing, using the processor, context data; disambiguating, using the processor, the command based on the context data; and committing, using the processor, a predetermined action according to the command. Other aspects are described and claimed.

Claims

1. A method, comprising:

receiving, at an audio receiver of an information handling device, user voice input;

identifying, using a processor, words included in the user voice input;

determining, using the processor, at least one of the identified words renders ambiguous a command included in the user voice input;

accessing, using the processor, context data;

disambiguating, using the processor, the command based on the context data; and

committing, using the processor, a predetermined action according to the command.

2. The method of claim 1, wherein the context data is derived from the voice input.

3. The method of claim 2, wherein the context data derived from the voice input includes an identified word included in the user voice input selected from the group of words consisting of a contact and an application name.

4. The method of claim 1, wherein the context data is derived from a list of open applications on the information handling device.

5. The method of claim 1, wherein the context data is derived from a list of most recently used applications on the information handling device.

6. The method of claim 1, wherein the context data is derived from a list of most recently used objects on the information handling device.

7. The method of claim 1, wherein the disambiguating comprises associating a context data item with the identified word rendering the command ambiguous.

8. The method of claim 7, wherein the associating comprises linking a device object to the identified word rendering the command ambiguous using the context data item.

9. The method of claim 8, further comprising replacing the identified word rendering the command ambiguous with a device object identifier.

10. The method of claim 9, wherein the device object identifier is a file name pointing to the device object subject to the command.

18. The information handling device of claim 7, wherein the associating comprises linking a device object to the identified word rendering the command ambiguous using the context data item.

19. The information handling device of claim 8, further comprising replacing the identified word rendering the command ambiguous with a device object identifier.

11. An information handling device, comprising:

an audio receiver;

a processor; and

a memory device that stores instructions executable by the processor to;

receive, at the audio receiver of an information handling device, user voice input;

identify words included in the user voice input;

determine one of the identified words renders ambiguous a command included in the user voice input;

access context data;

disambiguate the command based on the context data; and

commit a predetermined action according to the command.

12. The information handling device of claim 11, wherein the context data is derived from the voice input.

13. The information handling device of claim 12, wherein the context data derived from the voice input includes an identified word included in the user voice input selected from the group of words consisting of a contact and an application name.

14. The information handling device of claim 11, wherein the context data is derived from a list of open applications on the information handling device.

15. The information handling device of claim 11, wherein the context data is derived from a list of most recently used applications on the information handling device.

16. The information handling device of claim 11, wherein the context data is derived from a list of most recently used objects on the information handling device.

17. The information handling device of claim 11, wherein the disambiguating comprises associating a context data item with the identified word rendering the command ambiguous.

20. A product, comprising:

a storage device having code stored therewith, the code comprising;

code that receives at an audio receiver of an information handling device, user voice input;

code that identifies, using a processor, words included in the user voice input;

code that determines, using the processor, one of the identified words renders ambiguous a command included in the user voice input;

code that accesses, using the processor, context data;

code that disambiguates, using the processor, the command based on the context data; and

code that commits, using the processor, a predetermined action according to the command.
