TY - JOUR TI - Wav2Lip: A Lip Sync Expert Is All You Need AU - Prajwal, K. R. AU - Mukhopadhyay, R. AU - Namboodiri, V. P. AU - Jawahar, C. V. PY - 2020 DA - 2020/08// JO - ACM Multimedia 2020 AB - Prajwal, Mukhopadhyay, Namboodiri and Jawahar (2020) introduced Wav2Lip, an audio-driven lip-synchronisation method that uses a pretrained lip-sync expert discriminator as a teacher to train a generator producing accurate mouth movements for any speaker given an audio track. The key insight is using a discriminator specifically trained to judge lip-sync quality rather than general visual realism, producing accurate synchronisation on in-the-wild video without per-subject fine-tuning. Wav2Lip is speaker-agnostic and directly applicable to dubbing and dialogue-replacement workflows in animation and localisation. It became the open-source baseline cited by all subsequent talking-face and audio-driven animation research.
