Various embodiments of an apparatus, method(s), system(s) and computer program product(s) described herein are directed to a Viseme Engine. The Viseme Engine receives audio data associated with a user account. The Viseme Engine predicts at least one viseme that corresponds with a portion of phoneme audio data and identifies one or more facial expression parameters associated with the predicted viseme. The facial expression parameters being applicable to a face model. The Viseme Engine renders the predicted viseme according to the one or more facial expression parameters.

Methods, systems, and apparatus, including computer programs encoded on computer storage media related to video bandwidth optimization, and more particularly, to systems and methods for video resolution downscaling and upscaling a video communications platform. A first video stream comprising first multiple image frames of a first resolution is received. A modified video stream of a second resolution higher than the first resolution, is generated using a trained machine learning network. A user interface may display the modified video stream.

Video bandwidth optimization within a video communications platform

A best available video stream is determined for each of multiple conference participants within a conference room including multiple cameras based on scores determined for video streams obtained from the cameras. The scores are determined based on representations of the conference participants within the video streams, for example, based on percentages of conference participant faces visible within the video streams, directions of conference participant faces relative to the cameras, directions of eye gaze of the conference participants relative to the cameras, and/or degrees to which conference participant faces are obscured within the video streams. The best available video streams are output for rendering within separate user interface tiles of conferencing software.
