InfiniteTalk Multi-Speaker Dubbing
InfiniteTalk syncs each person in a photo or a clip to their own audio track, turning multi-speaker footage into naturally dubbed conversation video.
Working with InfiniteTalk
InfiniteTalk is built for more than one speaker. Its Multi variants take footage or a single photo containing several people and match each person's lips and expressions to their own audio track; the single-speaker variants do the same for one subject from either an image or a video.
When to choose InfiniteTalk
Choose InfiniteTalk when a scene has two or more people who each need their own audio. LatentSync and VEED Lipsync handle single-speaker footage; EchoMimic and Veed Fabric animate one portrait.
Choosing between the variants
The Multi variants are the reason to be here — Video to Video for existing multi-speaker footage, Image to Video to build a conversation from one photo. The single-speaker variants cover the simpler case from a clip or an image.
About InfiniteTalk
- Can InfiniteTalk handle two people in one photo?
- Yes. Multi Image-to-Video turns a photo of two or more people into a lip-synced conversation, with each speaker matched to their own track.
- Does it work on existing footage?
- Yes — the video-to-video variants transform multi-speaker footage into naturally dubbed video, syncing expressions as well as lips.
- How is it different from a single-speaker lipsync model?
- It assigns a separate audio track per person, which a single-speaker model cannot do without cutting the scene apart first.
