    Abstract: Systems and methods for providing voice feedback for video conferences are provided. A computer-implemented method includes joining, by a client device, a video conference hosted by a video conference provider, the video conference having a plurality of participants using a plurality of client devices. With voice feedback enabled, the client device may receive a first audio stream from the video conference provider, the first audio stream associated with a first participant of the plurality of participants and a second audio stream from a user of the client device, the second audio stream comprising a voice of the user of the client device. The client device can play the first audio stream on one or more channels of one or more audio devices connected to the client device and play the second audio stream on the one or more channels of the one or more audio devices.

    Abstract: Various embodiments of an apparatus, method(s), system(s) and computer program product(s) described herein are directed to a Visualization Engine. The Visualization Engine receives audio data associated with a user account accessing a virtual meeting via a communications environment client software application. The Visualization Engine detects presence of a pre-selected type(s) of audio event(s) in the received audio data. The Visualization Engine generates a visualization representative of at least one attribute of the detected audio event(s). During playback of the audio data in the virtual meeting, the Visualization Engine renders the visualization within the communications environment client software application of the user account.

    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media for generating echo recordings. The system receives, by an autoencoder, an audio signal representation that represents an audio signal and a target echo embedding that comprises information about a target room. The autoencoder comprises an encoder and a decoder. The system generates, by the encoder, a content embedding and an estimated echo embedding. The system generates, by the decoder, an echo recording representation based on the content embedding and the target echo embedding.

    Abstract: An apparatus and/or method discloses a video conference with enhanced audio quality using high-fidelity audio sharing (“HAS”). In one embodiment, a network connection between a first user equipment (“UE”) and a second UE is established via a communication network for providing an interactive real-time meeting. After sending a first calibration audio signal from the first UE to the second UE, a second calibration audio signal is retuned from the second UE to the first UE according to the first calibration audio signal. Upon identifying a far end audio (“FEA”) delay based on the first calibration audio signal and the second calibration audio signal, a first mixed audio data containing the first shared audio data and first FEA data is fetched from an audio buffer. The first FEA data is subsequently removed or extracted from the mixed audio data in response to the FEA delay.

    Abstract: An error resilience method comprising: using a computer, creating and storing, in computer memory, one or more FEC filter tables for use by the FEC filter for selectively forwarding a FEC packet; selectively forwarding a request for the FEC packet through a FEC filter based on the FEC table and a dynamic packet loss level at a receiver; limiting a re-transmission request for a particular packet through the FEC filter based on a number of re-transmission requests for the particular packet; and selectively skipping a key frame request based on a number of key frame requests received from a plurality receiver devices, wherein the method is performed by one or more special-purpose computing devices.
