Method and apparatus for providing noise suppression to an intelligent personal assistant
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.
1. A method for providing noise suppression capability to a system having a far field voice detection device, 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 method 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 method 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 method 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 method as recited in claim 4 , wherein the further device comprises a remote control device.
6. The method 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 method as recited in claim 6 , wherein the further device comprises a television.
8. The method 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 method 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 method 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 method for providing noise suppression capability to a system having a plurality of far field voice detection devices, comprising:
using each of a plurality of radio frequency connections between a respective each one of the plurality of far field voice detection devices and a remote control device to determine the one of the plurality of far field voice detection devices the remote control device is being pointed at; and
emphasizing, during a noise processing of a plurality of sounds received via use of the plurality of far field voice detection devices, a one of the plurality of sounds received via the determined one of the plurality of far field voice detection devices.
12. The method as recited in claim 11 , wherein emphasizing the one of the plurality of sounds received via the determined one of the plurality of far field voice detection devices comprises ignoring the plurality of sounds received via remaining ones of the plurality of far field voice detection devices.
13. The method as recited in claim 11 , wherein an angle of arrival direction finding methodology is used to determine the one of the plurality of far field voice detection devices the remote control device is being pointed at.
14. The method as recited in claim 11 , wherein an angle of departure direction finding methodology is used to determine the one of the plurality of far field voice detection devices the remote control device is being pointed at.
15. The method as recited in claim 11 , wherein the one of the plurality of far field voice detection devices the remote control device is being pointed at is caused to be determined in response to a detected utterance of a wake-word.
16. The method as recited in claim 11 , wherein the one of the plurality of far field voice detection devices the remote control device is being pointed at is caused to be determined in response to a detected interaction with the remote control device.
17. The method as recited in claim 11 , wherein the one of the plurality of far field voice detection devices the remote control device is being pointed at is caused to be periodically determined.
