Abstract

An embodiment provides a method, including: accepting, at an audio receiver of an information handling device, voice input of a user; interpreting, using a processor, the voice input; identifying, using a processor, at least one ambiguity in interpreting the voice input; thereafter accessing stored non-audible input associated in time with the at least one ambiguity; and adjusting an interpretation of the voice input using non-audible input. Other aspects are described and claimed.

Claims

1. A method, comprising:

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

interpreting, using a processor, the voice input;

identifying, using a processor, at least one ambiguity in interpreting the voice input;

thereafter accessing stored non-audible input associated in time with the at least one ambiguity; and

adjusting an interpretation of the voice input using non-audible input.

3. The method of claim 1, further comprising capturing, using a sensor, non-audible input associated in time with the at least one ambiguity.

4. The method of claim 3, wherein the sensor is a camera.

5. The method of claim 3, wherein said capturing proceeds according to a policy.

6. The method of claim 5, wherein said policy permits said capturing responsive to detecting a factor selected from the group consisting of:

history of low speech recognition confidence, detection of multiple speech candidates, a detection of background noise exceeding a predetermined threshold, detection of a repeated word, and detection of an atypical voice characteristic.

7. The method of claim 5, wherein said policy adjusts said capturing responsive to battery level falling below a predetermined threshold.

8. The method of claim 1, wherein the accessing stored non-audible input associated in time with the at least one ambiguity comprises accessing non-audible input derived from data selected from the group consisting of visible light image data, non-visible electromagnetic radiation image data, and non-audible sound data.

9. The method of claim 1, wherein the identifying, using a processor, at least one ambiguity in interpreting the voice input comprises identifying a word including a predetermined sound characteristic associated with ambiguity.

10. The method of claim 9, wherein the predetermined sound characteristic associated with ambiguity is a consonant sound.

2. The method of claim 2, wherein the adjusting comprises correcting the voice input.

11. An information handling device, comprising:

an audio receiver;

a sensor that captures input;

a processor; and

a memory storing instructions that are executed by the processor to;

accept, at the audio receiver, voice input of a user;

interpret the voice input;

identify at least one ambiguity in interpreting the voice input;

thereafter access stored non-audible input associated in time with the at least one ambiguity; and

adjust an interpretation of the voice input using non-audible input derived from the sensor.

13. The information handling device of claim 11, further wherein the instructions are further executable by the processor to capture non-audible input associated in time with the at least one ambiguity.

14. The information handling device of claim 13, wherein the sensor is a camera.

15. The information handling device of claim 13, wherein to capture comprises capturing non-audible input according to a policy.

16. The information handling device of claim 15, wherein said policy permits said capturing responsive to detecting a factor selected from the group consisting of:

history of low speech recognition confidence, detection of multiple speech candidates, a detection of background noise exceeding a predetermined threshold, detection of a repeated word, and detection of an atypical voice characteristic.

17. The information handling device of claim 15, wherein said policy adjusts said capturing responsive to battery level falling below a predetermined threshold.

18. The information handling device of claim 11, wherein to access stored non-audible input associated in time with the at least one ambiguity comprises accessing non-audible input derived from data selected from the group consisting of visible light image data, non-visible electromagnetic radiation image data, and non-audible sound image data.

19. The information handling device of claim 11, wherein the identifying, using a processor, at least one ambiguity in interpreting the voice input comprises identifying a word including a predetermined sound characteristic associated with ambiguity.

12. The information handling device of claim 12, wherein to adjust comprises correcting the voice input.

20. A product, comprising:

a device readable storage device having device readable code stored therewith, the device readable code being executable by a processor and comprising;

code that accepts voice input of a user;

code that interprets the voice input;

code that identifies at least one ambiguity in interpreting the voice input;

code that thereafter accesses stored non-audible input associated in time with the at least one ambiguity; and

code that adjusts an interpretation of the voice input using non-audible input.
