Lipsync
Voice replacement with auto lip-sync
Dub an existing video: upload a clip + new audio track — the model syncs lip movements with the new speech. Two models to choose from: Sync.so v3 (top quality) and HeyGen Speed (fast and cheap).
Model versions
Sync.so v3
Top model for lip-sync. Specifically trained on facial animation: lips synchronize with speech in high quality. Great for dubbing, voice replacement, video translation.
