Abstract: A videoconferencing endpoint is described that uses a combination of face detection, motion detection, and upper body detection for selecting participants of a videoconference for group framing. Motion detection is used to remove fake faces as well as to detect motion in regions around detected faces during postprocessing. Upper body detection is used in conjunction with the motion detection in postprocessing to allow saving faces that have been initially detected by face detection for group framing even if the participant has turned away from the camera, allowing the endpoint to keep tracking the participants region better than would be possible based only on an unstable result coming from face detection.

Abstract: A videoconferencing system has a videoconferencing unit that use portable devices as peripherals for the system. The portable devices obtain near-end audio and send the audio to the videoconferencing unit via a wireless connection. In turn, the videoconferencing unit sends the near-end audio from the loudest portable device along with near-end video to the far-end. The portable devices can control the videoconferencing unit and can initially establish the videoconference by connecting with the far-end and then transferring operations to the videoconferencing unit. To deal with acoustic coupling between the unit's loudspeaker and the portable device's microphone, the unit uses an echo canceller that is compensated for differences in the clocks used in the A/D and D/A converters of the loudspeaker and microphone.

Abstract: A device includes one or more processor devices, an audio sensor, a speaker device, and one or more memory devices. The audio sensor is configured to generate an audio stream. The one or more memory devices store data including data identifying a wake phrase and instructions. The instructions are executable by the one or more processor devices to initiate, as a result of detecting the wake phrase in the audio stream and determining that the wake phrase is invalid, presentation via the speaker device of audio output identifying a valid wake input. The instructions are further executable by the one or more processors to initiate, as a result of detecting the valid wake input, communication of a portion of the audio stream to a natural language processing service.

Abstract: A technique for merging conference session dialogs allows presenting content and media streams from a non-Skype endpoint to a Skype multipoint control unit (MCU), so that they present a single caller in a conference with both media and content. A signaling adapter intercepts session dialogs and merges or other modifies. When adding the non-Skype endpoint, requests from a content server are dropped while requests from the MCU handling non-Skype media streams are forwarded to the Skype MCU. Responses to the request from the MCU are also forwarded to the content server. When creating subscription dialogs, requests from the content server are modified to appear as if they came from the MCU, while responses go back to the proper requester. Conference notifications are forked to go to both the content server and the MCU. Because Skype uses separate media and content dialogs, merging of audio/video and content dialogs may be omitted. By merging dialogs, user experience is improved.

Abstract: A telepresence system which includes at least one display device and a beacon coupled to the display device. The beacon emits a signal so as to be discoverable by electronic devices nearby such as in a meeting location. The system also includes a receiver-controller coupled to the beacon, the receiver-controller configured to enable such electronic devices to be recognized and to join a collaborative session in which content from one electronic device can be shared with other electronic devices. The receiver-controller can and will share some or all of its functions with one or more of the joined devices simultaneously, if security and identity protocols are satisfied.

Abstract: The amount of far-field noise transmitted by a primary communication device in an open-plan office environment is reduced by defining an acoustic perimeter of reference microphones around the primary device. Reference microphones generate a reference audio input including far-field noise in the proximity of the primary device. The primary device generates a main audio input including the voice of the primary speaker as well as background noise. Reference audio input is compared to main audio input to identify the background noise portion of the main audio signal. A noise reduction algorithm suppresses the identified background noise in the main audio signal. The one or more reference microphones defining the acoustic perimeter may be included in separate microphone devices placed in proximity to the main desktop phone, microphones within other nearby desktop telephone devices, or a combination of both types of devices.
