Abstract

Compensating for identifiable background content in a speech recognition device, including: receiving, by a noise filtering module, an identification of environmental audio data received by the speech recognition device; and filtering, by the noise filtering module in dependence upon which portion of the identified environmental audio data was being rendered when the audio data generated from the plurality of sources was received, the audio data generated from the plurality of sources.

Claims

1. A method of compensating for identifiable background content in a speech recognition device, the method comprising:

receiving, by the noise filtering module via an out-of-band communications channel, an identification of environmental audio data received by the speech recognition device, wherein the environmental audio data is not generated by a user of the speech recognition device; and

filtering, by the noise filtering module in dependence upon which portion of the identified environmental audio data was being rendered when audio data generated by a plurality of sources was received, the audio data generated by the plurality of sources.

2. The method of claim 1 further comprising sending, by the noise filtering module, a request to create an out-of-band communications channel with a background noise producing device, the request including channel creation parameters.

3. The method of claim 1 further comprising receiving, by the noise filtering module from a background noise producing device, a request to create an out-of-band communications channel, the request including channel creation parameters.

4. The method of claim 1 wherein receiving, by the noise filtering module via an out-of-band communications link, an identification of environmental audio data received by the speech recognition device further comprises receiving timing information identifying which portion of the identified environmental audio data was being rendered when the audio data generated from the plurality of sources was received.

5. The method of claim 1 wherein receiving, by the noise filtering module via an out-of-band communications channel, the identification of environmental audio data received by the speech recognition device further comprises:

detecting, by the noise filtering module, that a voice command has been issued; and

responsive to detecting that the voice command has been issued, requesting, by the noise filtering module, the identification of environmental audio data received by the speech recognition device at the time that the voice command was issued.

6. The method of claim 1 further comprising executing, by the speech recognition device in dependence upon filtered audio data, one or more device actions.

7. An apparatus for compensating for identifiable background content in a speech recognition device, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the steps of:

receiving, by the noise filtering module via an out-of-band communications channel, an identification of environmental audio data received by the speech recognition device, wherein the environmental audio data is not generated by a user of the speech recognition device; and

filtering, by the noise filtering module in dependence upon which portion of the identified environmental audio data was being rendered when audio data generated by a plurality of sources was received, the audio data generated by the plurality of sources.

8. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of sending, by the noise filtering module, a request to create an out-of-band communications channel with a background noise producing device, the request including channel creation parameters.

9. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of receiving, by the noise filtering module from a background noise producing device, a request to create an out-of-band communications channel, the request including channel creation parameters.

10. The apparatus of claim 7 wherein receiving, by the noise filtering module via an out-of-band communications link, an identification of environmental audio data received by the speech recognition device further comprises receiving timing information identifying which portion of the identified environmental audio data was being rendered when the audio data generated from the plurality of sources was received.

11. The apparatus of claim 7 wherein receiving, by the noise filtering module via an out-of-band communications channel, the identification of environmental audio data received by the speech recognition device further comprises:

detecting, by the noise filtering module, that a voice command has been issued; and

responsive to detecting that the voice command has been issued, requesting, by the noise filtering module, the identification of environmental audio data received by the speech recognition device at the time that the voice command was issued.

12. The apparatus of claim 7 further comprising computer program instructions that, when executed by the computer processor, cause the apparatus to carry out the step of executing, by the speech recognition device in dependence upon filtered audio data, one or more device actions.

13. A computer program product for compensating for identifiable background content in a speech recognition device, the computer program product disposed upon a computer readable medium, the computer program product comprising computer program instructions that, when executed, cause a computer to carry out the steps of:

receiving, by the noise filtering module via an out-of-band communications channel, an identification of environmental audio data received by the speech recognition device, wherein the environmental audio data is not generated by a user of the speech recognition device; and

filtering, by the noise filtering module in dependence upon which portion of the identified environmental audio data was being rendered when audio data generated by a plurality of sources was received, the audio data generated by the plurality of sources.

14. The computer program product of claim 13 further comprising computer program instructions that, when executed, cause the computer to carry out the step of sending, by the noise filtering module, a request to create an out-of-band communications channel with a background noise producing device, the request including channel creation parameters.

15. The computer program product of claim 13 further comprising computer program instructions that, when executed, cause the computer to carry out the step of receiving, by the noise filtering module from a background noise producing device, a request to create an out-of-band communications channel, the request including channel creation parameters.

16. The computer program product of claim 13 wherein receiving, by the noise filtering module via an out-of-band communications link, an identification of environmental audio data received by the speech recognition device further comprises receiving timing information identifying which portion of the identified environmental audio data was being rendered when the audio data generated from the plurality of sources was received.

17. The computer program product of claim 13 wherein receiving, by the noise filtering module via an out-of-band communications channel, the identification of environmental audio data received by the speech recognition device further comprises:

detecting, by the noise filtering module, that a voice command has been issued; and

responsive to detecting that the voice command has been issued, requesting, by the noise filtering module, the identification of environmental audio data received by the speech recognition device at the time that the voice command was issued.

18. The computer program product of claim 13 further comprising computer program instructions that, when executed, cause the computer to carry out the step of executing, by the speech recognition device in dependence upon filtered audio data, one or more device actions.

19. The computer program product of claim 13 wherein the computer readable medium comprises a signal medium.

20. The computer program product of claim 13 wherein the computer readable medium comprises a storage medium.
