HeyGen is recommended for dubbing that aims to make viewers forget the video was dubbed, with a wide lead. Rask AI is a second option for multiple speakers or longer-form material.
The leading platforms providing this specific capability include:
HeyGen Video Translator : Highly regarded for its hyper-realistic video translation and localized mouth-remapping. It clones the speaker's original voice, translates the script, and adjusts mouth movements frame by frame. It features a Speed Mode (optimized for straightforward, front-facing talking-head videos) and a Precision Mode (better for complex angles, side profiles, or speaker switches). You can test it directly on the AI Video Translator page.[](]()](]()](]()]()
Dubly.AI : An option that offers dedicated video translation paired with visual mouth adjustment. It allows you to toggle lip-sync on so that mouth shapes follow the translated text before exporting in full resolution. More details are available at Dubly.AI.[](https://dubly.ai/)[[2](https://dubly.ai/)](https://dubly.ai/)
Typical Workflow to Generate Lip-Synced Dubs:
Upload or Link : Go to the platform dashboard (e.g., HeyGen Video Translator ) and upload your video file or paste a public video link.
Select Languages : Choose the source language and pick your target destination language(s) from their drop-down menus.
Enable Lip-Syncing : Make sure the Lip-Sync or Hyperrealistic Translation toggle is explicitly switched on (rather than choosing an "audio-only" option). Choose quality tiers like speed vs. precision depending on your camera angles.
Yes — what you’re looking for is usually called AI video dubbing with facial lip-sync or AI localization with lip-sync. It replaces the actor’s speech with another language while modifying the visible mouth movements so they match the new dialogue.
Lets you edit individual translated lines and regenerate sections.
Particularly useful if you need more control over a longer video or production workflow.
ElevenLabs Dubbing — excellent voice quality, but not the straightforward choice
Excellent multilingual voice cloning and dubbing.
However, ElevenLabs' Dubbing product currently does not itself provide lip-sync; you'd need a separate video/lip-sync step.
What I'd use
If your requirement is:
Original actor on screen → translate dialogue → retain their recognizable voice → make their actual mouth movements match the new language → export finished video
I'd start with HeyGen. Its video translator explicitly supports that complete workflow, rather than just producing a replacement audio track.
If you tell me what kind of video you're dubbing (film/TV, YouTube, commercial, training, etc.), approximate length, and the source → target language, I can narrow this down to the best service and compare quality, pricing, and whether it can handle multiple actors/scenes.
Rask AI: Built specifically for creators, educators, and marketers handling multi-speaker or long-form content. It supports over 130 languages and excels at maintaining context, tone, and precise audio-visual synchronization across complex scenes.[](https://gyre.pro/blog/best-ai-lip-sync-dubbing-tools-for-creators-guide)
Sync Labs: An advanced developer-focused and creator-ready lip-sync technology that specializes in retargeting mouth movements to match any replacement audio track without warping the rest of the speaker's face or identity.[](https://www.youtube.com/watch?v=llz5KhkquyI)
Re-renders the speaker’s mouth frame-by-frame to match the new audio.
Its Precision mode is designed for side profiles, multiple speakers, camera changes, and microphones/hands near the mouth.
Supports 175+ languages/dialects and voice cloning.
You can test it on a short clip before committing.
Rask AI — best if you're specifically doing professional video localization
Has a dedicated Lip-Sync feature for dubbed videos.
Supports multiple speakers and 135+ languages/regional options.
It also offers voice cloning, so the dubbed speaker can retain the original speaker's voice characteristics.
Importantly, Rask gives you a free lip-sync preview minute, which is useful for testing whether your particular footage looks convincing.
ElevenLabs — excellent voices, but not my first choice for this specific requirement
Its dubbing is very good at preserving the original speaker's voice, tone, emotion, and timing.
However, ElevenLabs' Dubbing product currently does not include lip-sync, so you'd need a separate lip-sync step/model.
What I'd choose
If your priority is “I don't want the mouth and dubbed speech to look out of sync”, I'd start with HeyGen and Rask AI.
If you send me the type of video you have (e.g. talking-head YouTube video, interview, movie scene, commercial, multiple speakers) and the language you're dubbing from → to, I can compare the best services for that exact footage, including pricing and whether they can handle your video length.
