Infinite Talk AI

InfiniteTalk AI is a sparse-frame video dubbing framework that generates lip-synced videos from audio input. It synchronizes not just lips but also head movements, body posture, and facial expressions with speech, supporting infinite-length video generation while preserving identity. The tool works in both audio-to-video and image-to-audio modes, enabling creators to dub existing videos or generate talking avatars from static images paired with audio tracks.
