Abstract
Systems and methods for automatic speech recognition are provided. Some methods can include a sensor 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 direction 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.
Claims20
A method comprising:
- a sensor 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 direction 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, the direction setting enhancing speech recognition by the multi-directional microphone array from the relative location of the user within the one of the plurality of voice pickup areas.
A system comprising:
- a multi-directional microphone array for recognizing speech commands from within a plurality of voice pickup areas;
- and
- a sensor deployed within or proximate to the plurality of voice pickup areas,
- wherein the sensor detects a relative location of a user within one of the plurality of voice pickup areas,
- wherein, responsive to the sensor detecting the relative location of the user within the one of the plurality of voice pickup areas, the multi-directional microphone array activates a direction 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, and
- wherein the direction setting enhances speech recognition by the multi-directional microphone array from the relative location of the user within the one of the plurality of voice pickup areas.
3 more elements
A system comprising:
- a plurality of sensors deployed in a region;
- a plurality of multi-directional microphone arrays deployed in the region for recognizing speech commands from within a respective plurality of voice pickup areas;
- and
- a control panel coupled to the plurality of sensors and the plurality of mufti-directional microphone arrays,
- wherein one of the plurality of sensors detects a relative location of a user within the region and sends first data indicative of the relative location of the user within the region to the control panel,
- wherein the control panel identifies one of the plurality of multi-directional microphone arrays for which one of the respective plurality of voice pickup areas is closest to to the relative location of the user within the region and, responsive thereto, transmits second data indicative of the relative location of the user within the region to the one of the plurality of multi-directional microphone arrays,
- wherein, responsive to receiving the second data, the one of the plurality of multi-directional microphone arrays activates a direction setting based on the relative location of the user within the one of the respective plurality of voice pickup areas, and
- wherein the direction setting enhances speech recognition by the one of the plurality of multi-directional microphone arrays from the relative location of the user within region.
