ByteDance LatentSync API
ByteDance LatentSync is an advanced AI-powered lip-syncing model designed to synchronize mouth movements in video with any audio input, generating natural, frame-accurate facial motion. Built on latent diffusion technology, it directly transforms audio into video expressions without relying on intermediate motion markers. Its TREPA-based temporal enhancement ensures smooth, stable, and highly consistent animations, making it ideal for creators, studios, dubbing workflows, and virtual avatar applications.
