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.

Abstract: A system and method for audio-visual multi-speaker speech separation, including: receiving audio signals captured by at least one microphone; receiving video signals captured by at least one camera; and applying 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.

Abstract: An exerciser apparatus for enabling exercising of facial muscles and jaws through movement of the jaws. The apparatus comprises a pair of flat spring arms which are pivotally connected to each other by 360.degree. convolutions which form a torque spring. The upper arm is provided with a receptacle or similar member to receive the upper teeth or gingiva and another receptacle or similar member is provided on the other of the arms to receive the lower teeth or gingiva. The torque spring biases the arms in a first direction and the user attempts to squeeze the arms together at one end against the action of the biasing mechanism.
