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.
Claims18
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.

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.
