Textbased Editing of Talkinghead Video Editing talkinghead video to change the speech content or to remove filler words is challenging. We propose a novel method to edit talkinghead video based on its transcript to produce a realistic output video in which the dialogue of the speaker has been modified, while maintaining a seamless audiovisual flow (i.e. no jump cuts). Our method automatically annotates an input talkinghead video with phonemes, visemes, 3D face pose and geometry, reflectance, expression and scene illumination per frame. To edit a video, the user has to only edit the transcript, and an optimization strategy then chooses segments of the input corpus as base material. The annotated parameters corresponding to the selected segments are seamlessly stitched together and used to produce an intermediate video representation in which the lower half of the face is rendered with a parametric face model. Finally, a recurrent video generation network transforms this representation to a photorealistic video that matches the edited transcript. We demonstrate a large variety of edits, such as the addition, removal, and alteration of words, as well as convincing language translation and full sentence synthesis.

Mining Audio, Text and Visual Information for Talking Face Generation Providing methods to support audiovisual interaction with growing volumes of video data is an increasingly important challenge for data mining. To this end, there has been some success in speechdriven lip motion generation or talking face generation. Among them, talking face generation aims to generate realistic talking heads synchronized with the audio or text input. This task requires mining the relationship between audio signaltext and lipsync video frames and ensures the temporal continuity between frames. Due to the issues such as polysemy, ambiguity, and fuzziness of sentences, creating visual images with lip synchronization is still challenging. To overcome the problems above, we present a datamining framework to learn the synchronous pattern between different channels from large recorded audiotext dataset and visual dataset, and apply it to generate realistic talking face animations. Specifically, we decompose this task into two steps: mouth landmarks prediction and video synthesis. First, a multimodal learning method is proposed to generate accurate mouth landmarks with multimedia inputs (both text and audio). Second, a network named Face2Vid is proposed to generate video frames conditioned on the predicted mouth landmarks. In Face2Vid, optical flow is employed to model the temporal dependency between frames, meanwhile, a selfattention mechanism is introduced to model the spatial dependency across image regions. Extensive experiments demonstrate that our method can generate realistic videos with background, and exhibit the superiorities on accurate synchronization of lip movements and smooth transition of facial movements.
