Abstract

A radio frequency connection between a far field voice detection device and a further device is used to determine a first angular direction from the far field voice detection device to the further device. The determined first angular direction is then used to emphasize, during a noise processing of a plurality of sounds received via use of a plurality of microphones of the far field voice detection device, a first one of the plurality of sounds relative to a remainder of the plurality of sounds.

First claim

What is claimed is:

1. A non-transitory, computer-readable media having instructions stored thereon, the instructions, when executed by a far field voice detection device, causing the far field voice detection device to perform steps, comprising:
using a radio frequency connection between the far field voice detection device and a further device to determine a first angular direction from the far field voice detection device to the further device; and
using the determined first angular direction to emphasize, during a noise processing of a plurality of sounds received via use of a plurality of microphones of the far field voice detection device, a first one of the plurality of sounds relative to a remainder of the plurality of sounds.

2. The non-transitory, computer-readable media as recited in claim 1 , wherein the first angular direction from the far field voice detection device to the further device is determined via use of an angle of arrival direction finding methodology.

3. The non-transitory, computer-readable media as recited in claim 1 , wherein the first angular direction from the far field voice detection device to the further device is determined via use of an angle of departure direction finding methodology.

4. The non-transitory, computer-readable media as recited in claim 1 , wherein each of the plurality of sounds arrives at the far field voice detection device from a corresponding one of a plurality of angular directions and the first one of the plurality of sounds arrives at the far field voice detection device from a first one of a plurality of angular directions that most closely corresponds to the first angular direction.

5. The non-transitory, computer-readable media as recited in claim 4 , wherein the further device comprises a remote control device.

6. The non-transitory, computer-readable media as recited in claim 1 , wherein each of the plurality of sounds arrives at the far field voice detection device from a corresponding one of a plurality of angular directions and the first one of the plurality of sounds arrives at the far field voice detection device from a first one of a plurality of angular directions that least closely corresponds to the first angular direction.

7. The non-transitory, computer-readable media as recited in claim 6 , wherein the further device comprises a television.

8. The non-transitory, computer-readable media as recited in claim 1 , wherein the first angular direction from the far field voice detection device to the further device is caused to be determined in response to a detected utterance of a wake-word.

9. The non-transitory, computer-readable media as recited in claim 1 , wherein the first angular direction from the far field voice detection device to the further device is caused to be determined in response to a powering on of the far field voice detection device.

10. The non-transitory, computer-readable media as recited in claim 1 , wherein the first angular direction from the far field voice detection device to the further device is caused to be periodically determined.

11. A far field voice detection device, comprising:
a radio frequency receiver for providing a radio frequency connection between the far field voice detection device and a further device;
a processing device;
a plurality of microphones; and
a memory having instructions stored thereon, the instructions, when executed by the processing device, causing the far field voice detection device to perform steps, comprising:
using the radio frequency connection between the far field voice detection device and the further device to determine a first angular direction from the far field voice detection device to the further device; and
using the determined first angular direction to emphasize, during a noise processing of a plurality of sounds received via use of the plurality of microphones of the far field voice detection device, a first one of the plurality of sounds relative to a remainder of the plurality of sounds.

12. The far field voice detection device as recited in claim 11 , wherein the first angular direction from the far field voice detection device to the further device is determined via use of an angle of arrival direction finding methodology.

13. The far field voice detection device as recited in claim 11 , wherein the first angular direction from the far field voice detection device to the further device is determined via use of an angle of departure direction finding methodology.

14. The far field voice detection device as recited in claim 11 , wherein each of the plurality of sounds arrives at the far field voice detection device from a corresponding one of a plurality of angular directions and the first one of the plurality of sounds arrives at the far field voice detection device from a first one of a plurality of angular directions that most closely corresponds to the first angular direction.

15. The far field voice detection device as recited in claim 14 , wherein the further device comprises a remote control device.

16. The far field voice detection device as recited in claim 11 , wherein each of the plurality of sounds arrives at the far field voice detection device from a corresponding one of a plurality of angular directions and the first one of the plurality of sounds arrives at the far field voice detection device from a first one of a plurality of angular directions that least closely corresponds to the first angular direction.

17. The far field voice detection device as recited in claim 16 , wherein the further device comprises a television.

18. The far field voice detection device as recited in claim 11 , wherein the first angular direction from the far field voice detection device to the further device is caused to be determined in response to a detected utterance of awake-word.

19. The far field voice detection device as recited in claim 11 , wherein the first angular direction from the far field voice detection device to the further device is caused to be determined in response to a powering on of the far field voice detection device.

20. The far field voice detection device as recited in claim 11 , wherein the first angular direction from the far field voice detection device to the further device is caused to be periodically determined.
