Center node: "photorealistic lip sync with adversarial temporal convolutional networks"
  Abstract: Lip sync has emerged as a promising technique to generate mouth movements on a talking head. However, synthesizing a clear, accurate and human-like performance is still challenging. In this paper, we present a novel lip-sync solution for producing a high-quality and photorealistic talking head from speech. We focus on capturing the specific lip movement and talking style of the target person. We model the seq-to-seq mapping from audio signals to mouth features by two adversarial temporal convolutional networks. Experiments show our model outperforms traditional RNN-based baselines in both accuracy and speed. We also propose an image-to-image translation-based approach for generating high-resolution photoreal face appearance from synthetic facial maps. This fully-trainable framework not only avoids the cumbersome steps like candidate-frame selection in graphics-based rendering methods but also solves some existing issues in recent neural network-based solutions. Our work will benefit related applications such as conversational agent, virtual anchor, tele-presence and gaming.
