Lip sync that feels natural
Frame-accurate lip synchronization powered by AI — so dubbed videos look and feel like they were always recorded in the target language.
How it works
Upload your video
Provide the original video in any format. Ollang ingests audio and visual tracks simultaneously.
AI speech synthesis
Our model generates natural-sounding speech in the target language, perfectly timed to on-screen mouth movements.
Pixel-perfect sync
Lip movements are adjusted frame-by-frame so dubbed speech matches the speaker's natural expression.
