Abstract

Systems and methods for speech recognition are provided. Some methods can include detecting a relative location of a user within one of a plurality of voice pickup areas of a multi-directional microphone array and the multi-directional microphone array activating a setting of the multi-directional microphone array based on the relative location of the user within the one of the plurality of voice pickup areas.

Claims (30)

1. A security or home automation system comprising:

a multi-directional microphone array that includes a plurality of microphones each of which corresponds to a respective one of a plurality of voice pickup areas; and

control circuitry in communication with the multi-directional microphone array,

wherein the control circuitry is configured to receive information identifying a location of a user relative to the multi-directional microphone array,

wherein, after receiving information identifying the location of the user relative to the multi-directional microphone array, the control circuitry is configured to transmit instructions to the multi-directional microphone array to enter a first microphone setting, wherein the first microphone setting comprises activation of a first microphone of the plurality of microphones,

wherein, after entering the first microphone setting, the first microphone is configured to detect a wakeup command at the multi-directional microphone array, and

wherein, responsive to detecting the wakeup command at the first microphone and while in the first microphone setting, the multi-directional microphone array is configured to enter an active listening mode at the multi-directional microphone array.

2. The security or home automation system of claim 1 , wherein the control circuitry is configured to receive a first signal from a first sensor in or proximate to a first area of the plurality of voice pickup areas.

3. The security or home automation system of claim 2 , wherein the first signal comprises the information identifying the location of the user relative to the multi-directional microphone array.

4. The security or home automation system of claim 3 , wherein the first signal is indicative of the first sensor detecting the user in the first area of the plurality of voice pickup areas.

5. The security or home automation system of claim 1 , wherein each of the plurality of microphones is capable of detecting sound from a respective one of a plurality of directions surrounding the multi-directional microphone array.

6. The security or home automation system of claim 1 , wherein the wakeup command includes a voice command of the user.

7. The security or home automation system of claim 1 , wherein, responsive to detecting the wakeup command at the multi-directional microphone array and while in the first microphone setting, the multi-directional microphone array directs a beamforming function of a first microphone of the plurality of microphones towards a first area of the plurality of voice pickup areas.

8. The security or home automation system of claim 1 , wherein the control circuitry uses the information identifying the location of the user relative to the multi-directional microphone array to configure the first microphone setting.

9. The security or home automation system of claim 8 , wherein the first microphone setting includes activation of a first microphone of the plurality of microphones corresponding to a first voice pickup area of the plurality of voice pickup areas.

10. A method comprising:

associating each of a plurality of microphones of a multi-directional microphone array with a respective one of a plurality of voice pickup areas;

communicating with the multi-directional microphone array via control circuitry that receives information identifying a location of a user relative to the multi-directional microphone array;

after receiving information identifying the location of the user relative to the multi-directional microphone array, transmitting, via the control circuitry, instructions to the multi-directional microphone array to enter a first microphone setting, wherein entering the first microphone setting comprises activating a first microphone of the plurality of microphones;

after entering the first microphone setting, detecting, via the first microphone, a wakeup command at the multi-directional microphone array; and

responsive to detecting the wakeup command at the first microphone and while in the first microphone setting, entering an active listening mode at the multi-directional microphone array.

11. The method of claim 10 , further comprising:

receiving a first signal from a first sensor in or proximate to a first of the plurality of voice pickup areas.

12. The method of claim 11 , wherein the first signal comprises the information identifying the location of the user relative to the multi-directional microphone array.

13. The method of claim 12 , wherein the first signal is indicative of the first sensor detecting the user in the first of the plurality of voice pickup areas.

14. The method of claim 10 , wherein each of the plurality of microphones is capable of detecting sound from a respective one of a plurality of directions surrounding the multi-directional microphone array.

15. The method of claim 10 , wherein the wakeup command includes a voice command of the user.

16. The method of claim 10 , wherein, responsive to detecting the wakeup command at the multi-directional microphone array and while in the first microphone setting, directing, via the multi-directional microphone array, a beamforming function of a first microphone of the plurality of microphones towards a first area of the plurality of voice pickup areas.

17. The method of claim 10 , wherein the information identifying the location of the user relative to the multi-directional microphone array is used to configure the first microphone setting.

18. The method of claim 17 , wherein the first microphone setting includes activation of a first microphone of the plurality of microphones corresponding to a first voice pickup area of the plurality of voice pickup areas.
