Abstract: A communication system with a noise cancellation (NC) assembly providing adaptive or dynamic noise cancellation. The NC assembly includes a localizer module determining, during a communication session (active speaking or during idle times), a location of the active talker. The NC assembly includes a beam generator forming a beam in the determined direction of the active talker to enhance the active talker speech. Once the NC assembly has determined the position of the active talker, the NC assembly assigns a microphone of the microphone array or generated beam in that active direction to be the “active signal” source. The NC assembly assigns a second microphone or beam to be the noise source for NC purposes, and this source may be selected to be in acoustic shadow of the first microphone used as the active signal source or may be the farthest away in its position from the active talker's position.

Abstract: A method for rotating a field of view represented by a displayed image is disclosed. The method may include displaying a first image representing a first field of view. The method may also include determining a gaze direction of a user toward the first image. The method may further include identifying a subject in the first image at which the gaze direction is directed, wherein the subject is in a first direction from a center of the first image. The method may further include receiving a directional input in a second direction. The method may additionally include, based at least in part on the second direction being substantially the same as the first direction, displaying a second image representing a second field of view, wherein the subject is centered in the second image.

Abstract: An apparatus is configured to rest on a wearer's neck or shoulders, and has a first microphone positioned at a first position located on the right side of the wearer, when the apparatus is worn, and a second microphone positioned at a second position located on the left side of the wearer. A processor receives audio signals output by the first and second microphones, and compares the audio signals from the first microphone to the audio signals from the second microphone. Based on the comparison, the processor determines whether the wearer's head is rotated to the right, left, or center, during an instance of the user speaking. Based on the determination, the processor selects a first one of at least two audio signal destinations, and provides the audio signal from at least one of the microphones to the first selected audio signal destination.

Abstract: An echo cancellation system that performs audio beamforming to separate audio input into multiple directions and determines a target signal and a reference signal from the multiple directions. For example, the system may detect a strong signal associated with a speaker and select the strong signal as a reference signal, selecting another direction as a target signal. The system may determine a speech position and may select the speech position as a target signal and an opposite direction as a reference signal. The system may create pairwise combinations of opposite directions, with an individual direction being selected as a target signal and a reference signal. The system may select a fixed beamformer output for the target signal and an adaptive beamformer output for the reference signal, or vice versa. The system may remove the reference signal (e.g., audio output by the loudspeaker) to isolate speech included in the target signal.
