Zusammenfassung: | This specification relates to robots and audio processing in robots. In general, one innovative aspect of the subject matter described in this specification can be embodied in a robot that includes: a body and one or more physically moveable components; a plurality of microphones and one or more other sensor subsystems; one or more processors; and one or more storage devices storing instructions that are operable, when executed by the one or more processors, to cause the robot to perform operations. The operations can include: receiving one or more sensor inputs from the one or more other sensor subsystems; determining a predicted direction of a detected sound emitter based on the one or more sensor inputs of the one or more other sensor subsystems; calculating a spatial filter based on the predicted direction; obtaining, by the plurality of microphones, respective audio inputs; and processing the respective audio inputs according to the calculated spatial filter. |
