Abstract: A system for audio-visual multi-speaker speech separation. The system includes a processing circuitry and a memory containing instructions that, when executed by the processing circuitry, configure the system to: receive audio signals captured by at least one microphone; receive video signals captured by at least one camera; and apply audio-visual separation on the received audio signals and video signals to provide isolation of sounds from individual sources, wherein the audio-visual separation is based, in part, on angle positions of at least one speaker relative to the at least one camera. The system provides for reliable speech processing and separation in noisy environments and environments with multiple users.

Abstract: A voice-controlled device, comprising at least one hardware processor adapted for receiving a set of preferred local commands or computing thereof by receiving from at least one other voice-controlled device a set of used commands and identifying in a plurality of voice commands a set of preferred local commands not members of the set of used commands; and responding to at least one voice command, received from a user, subject to identifying the at least one voice command in the set of preferred local commands, otherwise declining to respond thereto.
