Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for a voice command recognition system (VCR). An example embodiment operates by receiving a voice command directed to controlling a device, the voice command including a wake command and an action command. An amplitude of the wake command is determined. A gain adjustment for the voice command is calculated based on a comparison of the amplitude of the wake command to a target amplitude. An amplitude of the action command is adjusted based on the calculated gain adjustment for the voice command based on the comparison of the amplitude of the wake command to the target amplitude. A device command for controlling the device is identified based on the action command comprising the adjusted amplitude. The device command is provided to the device.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for selecting a digital assistant from among multiple digital assistants. An embodiment operates by receiving a voice input containing a trigger word at a first voice adapter associated with a digital assistant that generates a first confidence score for the trigger word. The embodiment further receives the voice input at a second voice adapter that generates a second confidence score for the trigger word. The embodiment determines the first confidence score is higher than the second confidence score. The embodiment selects the digital assistant based on the determining.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for reducing irrelevant alerts and/or network bandwidth usage from Internet of Things (IoT) cameras through the intelligent filtering out of video data. An example embodiment operates by receiving video data from an IoT camera. The embodiment further generates an ignore mask based on the video data, wherein the ignore mask specifies one or more regions in a video stream from the IoT camera that cannot trigger an alert. The embodiment then transmits the ignore mask to the IoT camera. The embodiment then receives the video stream from the IoT camera in response to transmitting the ignore mask to the IoT camera. The embodiment then determines that the video stream is associated with the alert. The embodiment may then transmit the alert to a user device in response to the determining.

Abstract: Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for sharing video streams in a camera system network. The video streams may be modified and/or masked to obscure private video stream features from being shared. An example embodiment operates by linking a first camera system to a first user device. The first camera system detects a second camera system in its field of view, wherein the second camera system is linked to a second user device. Upon exchanging requests to share video streams, the first and second user devices may view the video streams from both camera systems. The video streams may be modified to mask and/or obscure private property and/or known persons to preserve privacy despite sharing video streams. For example, the first camera system may modify and stream a masked video stream to the second user device.
