Figure 1: Our novel Wav2Lip model produces significantly more accurate lip-synchronization in dynamic, unconstrained talking face videos. Quantitative metrics indicate that the lip-sync in our generated videos are almost as good as real-synced videos.Thus, we believe that our model can enable a wide range of real-world applications where previous speaker-independent lipsyncing approaches [17,18] struggle to produce satisfactory results.

Humans involuntarily tend to infer parts of the conversation from lip movements when the speech is absent or corrupted by external noise. In this work, we explore the task of lip to speech synthesis, i.e., learning to generate natural speech given only the lip movements of a speaker. Acknowledging the importance of contextual and speakerspecific cues for accurate lip-reading, we take a different path from existing works. We focus on learning accurate lip sequences to speech mappings for individual speakers in unconstrained, large vocabulary settings. To this end, we collect and release a large-scale benchmark dataset, the first of its kind, specifically to train and evaluate the singlespeaker lip to speech task in natural settings. We propose a novel approach with key design choices to achieve accurate, natural lip to speech synthesis in such unconstrained scenarios for the first time. Extensive evaluation using quantitative, qualitative metrics and human evaluation shows that our method is four times more intelligible than previous works in this space.

Figure 1: In light of the increasing amount of audio-visual content in our digital communication, we examine the extent to which current translation systems handle the different modalities in such media. We extend the existing systems that can only provide textual transcripts or translated speech for talking face videos to also translate the visual modality i.e. lip and mouth movements. Consequently, our proposed pipeline produces fully translated talking face videos with corresponding lip synchronization. ABSTRACTIn light of the recent breakthroughs in automatic machine translation systems, we propose a novel approach that we term as "Faceto-Face Translation". As today's digital communication becomes increasingly visual, we argue that there is a need for systems that can automatically translate a video of a person speaking in language A into a target language B with realistic lip synchronization. In this work, we create an automatic pipeline for this problem and demonstrate its impact in multiple real-world applications. First, we

Figure 1: We address the problem of generating speech from silent lip videos for any speaker in the wild. Previous works train either on large amounts of data of isolated speakers or in laboratory settings with a limited vocabulary. Conversely, we can generate speech for the lip movements of arbitrary identities in any voice without additional speaker-specific fine-tuning. Our new VAE-GAN approach allows us to learn strong audio-visual associations despite the ambiguous nature of the task.
