Emo-LiveSync: Real-Time Universal Lip Synchronization with Explicit Emotion Control

Emo-LiveSync is a real‑time universal lip‑sync video generation framework that builds on LivePortrait and a warp‑based portrait animation model. By aligning audio signals to an implicit motion space through knowledge distillation from a pre‑trained video‑to‑motion model, it achieves high visual fidelity and lip‑sync accuracy while remaining computationally efficient. The method also introduces an expressive control gate for explicit emotion manipulation, enabling content enrichment and generalization to stylized characters beyond photo‑realistic humans.

Personalizing Causal Audio-Driven Facial Motion via Dynamic Multi-modal Retrieval

The paper introduces an end‑to‑end framework for personalized audio‑driven facial motion that operates in real time without look‑ahead. It combines a causal multi‑resolution motion tokenizer, which captures both global temporal context and fine articulatory details, with a multi‑modal style retriever that pulls stylistic priors from arbitrary reference footage using ongoing audio and motion queries. This approach allows high‑fidelity, identity‑consistent animation from just a few casually recorded clips, outperforming existing methods in lip‑sync accuracy, identity consistency, and perceived realism while maintaining real‑time streaming constraints.

FacEDiT: Talking Head Video Editing via Facial Motion Infilling

FacEDiT is a mask‑controlled model for editing local segments of talking head videos by infilling facial motion from speech and surrounding context. It uses a self‑supervised pretext task that masks a motion span during training, enabling variable‑duration local rewriting while preserving identity, unedited regions, and boundary continuity. The authors also release FacEDiTBench, a benchmark covering diverse edit types and lengths, and demonstrate that FacEDiT achieves accurate, speech‑aligned edits with strong identity preservation and seamless transitions.

GaussianEmoTalker: Real-Time Emotional Talking Head Synthesis with Audio-Driven and Blendshape-Based 3D Gaussian Splatting

Audio-driven talking head synthesis has achieved impressive progress in lip synchronization and visual quality, yet generating expressive emotional avatars with controllable intensity remains challenging, especially under real-time constraints. In this paper, we present GaussianEmoTalker, an audio-driven framework for real-time emotional talking head synthesis based on 3D Gaussian Splatting.
