In plain words: A system turns new text into speech and a video of someone saying it, mouth moves timed to the audio. Unlike lip-sync tools that use hand-built graphics code, every part is learned from data; it is the first to make both from text alone.

Abstract · ObamaNet: Photo-realistic lip-sync from text

We present ObamaNet, the first architecture that generates both audio and synchronized photo-realistic lip-sync videos from any new text. Contrary to other published lip-sync approaches, ours is only composed of fully trainable neural modules and does not rely on any traditional computer graphics methods. More precisely, we use three main modules: a text-to-speech network based on Char2Wav, a time-delayed LSTM to generate mouth-keypoints synced to the audio, and a network based on Pix2Pix to generate the video frames conditioned on the keypoints.
