It synthesizes realistic lip movements, head poses, and facial expressions synchronized to a spoken audio track, using either a single still image or a small set of reference video frames as the visual source. The system can produce videos of arbitrary length while maintaining temporal coherence, and it supports animating multiple subjects in a single scene. A key differentiator is the ability to coordinate multiple talking subjects through a structured JSON description, giving each independent lip sync and motion. The system can infer plausible head and body motion from a single static image, and it provides an interactive web interface for uploading media and generating videos without command-line interaction. An audio-visual feature alignment network ensures accurate lip sync across varying speech rates, and temporal recurrent frame generation keeps motion smooth over long durations. ## Tags ### Artificial Intelligence & ML - [Talking Head Generators](https://awesome-repositories.com/f/artificial-intelligence-ml/talking-head-generators.md) — Generates talking head videos from an audio track and sparse-frame references, with lip-sync and consistent head motion.
