Abstract: A method for hybrid noise suppression. The method involves obtaining a noisy audio input signal, generating a noise-suppressed audio output signal by performing a combination of a noise spectrum estimate-based noise suppression and a machine learning-based noise suppression, and outputting the noise-suppressed audio output signal.

Abstract: Methods and apparatuses for heart rate detection are described. In one example, a headphones apparatus and method includes emitting a first light in a first light direction directed at a left ear location from a left ear light emitter, and detecting a detected first light at a left ear light detector following interaction of the first light with a left ear tissue. The method includes emitting a second light in a second light direction directed at a right ear location from a right ear light emitter, the right ear location different from the left ear location. The method further includes detecting a detected second light at a right ear light detector following interaction of the second light with a right ear tissue, and estimating a heart rate from the detected first light and the detected second light.

Abstract: A video conferencing device for video conferencing between at least one local participant and a remote participant includes a video camera, a microphone array, and a speaker tracker. The video camera provides a local video input signal. The microphone array provides a local audio input signal. The speaker tracker is configured to identify a local speaker from the at least one local participant using a sound source localizer. The video conferencing device processes the local video input signal without the local speaker, based on the video conferencing device receiving a signal from a computing system, the signal dependent on a loopback audio output signal indicating that the remote participant is speaking.

Abstract: A method is disclosed for performing extension mobility via a headset connection. The method includes receiving a headset identifier from a headset. Also, the method includes, in response to receiving the headset identifier, sending the headset identifier to a device management server. Further, the method includes receiving a call control user identifier from the device management server, and sending, to a call control server, the call control user identifier. Still yet, the method includes receiving, from the call control server, a configuration profile associated with the call control user identifier. One or more settings of a desk phone are configured using the configuration profile.

Abstract: The frame or image of a video stream of a videoconference is divided into a series of segments for analysis. There is a primary grid, which covers the entire frame, and an alternate grid, which is shifted from the primary grid. Each segment is small enough to allow a neural network to efficiently operate on the segment without requiring downsampling. By operating on full resolution images, a participant can be identified at a greater distance from the camera. The entire frame is analyzed at a lower frequency, such as once per five seconds, but each segment containing a participant in the conference is scanned at a higher frequency, such as once per second, to maintain responsiveness to participant movement but also allow the full resolution operation.

Abstract: A method implementing dynamic camera presets. An image is received. A list of bounding boxes and a list of classification values are generated from the image. A set of tags, for the image, are generated from the list of bounding boxes and the list of classification values. A tagged image incorporating the set of tags into the image is presented. In response to a user input, a tag selection identifying a tag of the set of tags is received. View settings are adjusted to focus on a bounding box, from the list of bounding boxes, corresponding to the tag selection. An adjusted image is presented using the view settings.

Abstract: A method is disclosed for forking call audio channels. The method includes, during an active call, receiving a first audio stream of first call audio that originates from a far-end telephony device, and receiving a second audio stream of second call audio that originates from a microphone of a near-end headset. Further, the method includes generating, during the active call, a third audio stream containing the first call audio by processing the first audio stream, and generating a fourth audio stream containing the second call audio by processing the second audio stream. Still yet, the method includes, during the active call, generating a fifth audio stream containing the first call audio, and generating a sixth audio stream containing the second call audio.

Abstract: An apparatus includes an interface for microphones, a separated source processor configured to analyze channels from the microphones, and a voice activity detector (VAD) circuit. The VAD circuit is configured to generate a voice estimate (VE) value. The VE value is to indicate a likelihood of human speech received by the microphones. Generating the VE value includes adjusting the VE value based upon a delay between two of the microphones. The VAD circuit is configured to provide the VE value to the separated source processor.

Abstract: Methods and apparatuses for detecting user speech are described. In one example, a method for detecting user speech includes receiving a microphone output signal corresponding to sound received at a microphone and identifying a spoken vowel sound in the microphone signal. The method further includes outputting an indication of user speech detection responsive to identifying the spoken vowel sound.

Abstract: Embodiments of the present disclosure include an apparatus with a camera. A shutter is positioned horizontally in front of the lens of the camera. The shutter is configured to move in front of a lens of the camera and is further configured to move orthogonally to the horizontal axis so as to at least partially obscure the lens of first camera in a closed shutter position. The apparatus further includes a motor positioned horizontally behind the front of the lens of the camera. The motor is configured to move the shutter orthogonally to the horizontal axis between the closed shutter position and an open shutter position.

Abstract: A method for hybrid noise suppression includes receiving a processed audio signal from an audio device. The processed audio signal results from a partial audio processing performed on a noisy audio input signal. The method further includes predicting a noise suppression parameter using a neural network model operating on the processed audio signal and generating a noise-suppressed audio signal from the processed audio signal, using the noise suppression parameter. The method further includes generating a noise-suppressed audio output signal from the noise-suppressed audio signal using an additional audio processing and outputting the noise-suppressed audio output signal.

Abstract: The development of a region of interest (ROI) video frame that includes only ROIs of interest and not other elements and providing the ROI video frames in a single video stream simplifies the development of gallery view continuous presence displays. ROI position and size information metadata can be provided or subpicture concepts of the particular codec can be used to separate the ROIs in the ROI video frame. Metadata can provide perspective/distortion correction values, speaker status and any other information desired about the participant or other ROI, such as name. Only a single encoder and a single decoder is needed, simplifying both transmitting and receiving endpoints. Only a single video stream is needed, reducing bandwidth requirements. As each participant can be individually isolated, the participants can be provided in similar sizes and laid out as desired in a continuous presence display that is pleasing to view.
