HANDSFREE BEAM PATTERN CONFIGURATION
First Claim
1. A method for adjusting sound emitted by a loudspeaker array, comprising:
- sensing, by one or more microphone arrays, a voice command from a user in a listening area;
determining a location in the listening area to steer a beam pattern based on the sensed voice command; and
steering the beam pattern at the determined location in the listening area.

Abstract
An audio system that adjusts one or more beam patterns emitted by one or more loudspeaker arrays based on the preferences of users/listeners is described. The audio system includes an audio receiver that contains a listener location estimator, a listener identifier, and a voice command processor. Inputs from the listener location estimator, the listener identifier, and the voice command processor are fed into an array processor. The array processor drives the one or more loudspeaker arrays to emit beam patterns into the listening area based on inputs from each of these devices. By examining the location, preferred usage settings, and voice commands from listeners, the generated beam patterns are customized to the explicit and implicit preferences of the listeners with minimal direct input. Other embodiments are also described.

10. An audio system for adjusting sound emitted by one or more loudspeaker arrays, comprising:
-
a plurality of microphones to sense a voice command from a listener; a voice command processor to determine a first setting to apply to a beam pattern emitted by one of the one or more loudspeaker arrays based on signals representing the sensed voice command received from the plurality of microphones; and an array processor to generate a set of driving signals to drive each transducer in the one of the one or more loudspeaker arrays to emit the beam pattern based on the determined first setting. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. An article of manufacture for adjusting sound emitted by a loudspeaker array, comprising:
a non-transitory machine-readable storage medium that stores instructions which, when executed by a processor in a computing device, detect, from microphone signals, a voice command from a user in a listening area; determine a location in the listening area to steer a beam pattern based on the detected voice command; and steer the beam pattern at the determined location in the listening area. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
