I need a dubbing service that uses AI to lip-sync the original actor's face to the new language.

Several advanced AI platforms specialize in video translation, voice cloning, and precise facial/mouth re-shaping (lip-syncing) to make it look as though the original actor is fluently speaking the new language.

The top industry choices for AI video translation with visual lip-syncing include:

- **What it does:** Excellent at translating video into dozens of languages while cloning the original speaker's voice and morphing the mouth/lips frame-by-frame to match the new phonetic output.
- **Key features:** Preserves vocal tone, offers precision and speed modes, and includes a script proofreading dashboard to fine-tune translations.
- **Where to start:** Try it out via the HeyGen Video Translator.[](https://www.heygen.com/translate) [[1]](https://www.heygen.com/translate)[[2]](https://www.youtube.com/watch?v=JnMQ7nMxOlw&vl=en)[[3]](https://www.youtube.com/watch?v=BQbIZv6TZG4)[[4]](https://www.youtube.com/watch?v=-aZOfkMHwKI)

- **What it does:** Built specifically for localization and multi-speaker video dubbing. It features a robust AI Lip-Sync tool that adjusts mouth movements to fit the pacing of the target audio track across over 130 languages.
- **Key features:** Voice cloning, multi-speaker detection, and context-aware translation tailored for creators and enterprises.
- **Where to start:** Explore the tool on the [Rask AI Lip-Sync Generator](https://www.rask.ai/tools/lip-sync).[[1]](https://www.youtube.com/watch?v=8wDcedvs_hY&t=188)[[2]](https://www.rask.ai/tools/lip-sync)

- **What it does:** Provides automated video translation paired with high-fidelity visual lip-syncing, handling complex audio tracks like background noise or music underneath the dialogue.
- **Key features:** Retains original rights/data privacy and focuses on natural mouth shapes in multiple target languages.
- **Where to start:** Test capabilities or request a demo via [Dubly.AI](https://dubly.ai/).[[1]](https://dubly.ai/)

- **What it does:** If you already have the translated audio track or want a dedicated engine purely focused on realistic facial tracking and mouth alignment, Sync specializes strictly in high-end video lip-syncing.
- **Key features:** Stable face tracking and specialized models for different cinematic angles or lighting setups.
- **Where to start:** Check out workflows on Sync.so.[](https://www.youtube.com/watch?v=InzBazMU2sQ) [[1]](https://www.youtube.com/watch?v=InzBazMU2sQ)

If you'd like to narrow this down, let me know:

• How long is your source video?
• How many speakers are in the frame?
• Do you need multilingual output or just one specific target language?

If you mean AI dubbing that actually modifies the actor’s mouth movements so the new language looks like the actor originally spoke it, you’ll want a lip-sync localization service rather than a normal AI voice dubbing tool.

Some strong options:

• LipDub AI — Built specifically for multilingual dubbing with frame-by-frame lip sync, voice cloning, translation, and export workflows. It supports 80+ languages and targets broadcast-quality localization.
• DubDuck — Focuses on “same performance, new language” workflows: voice cloning, translation, multi-speaker handling, and lip-synced output.
• Vaani — Offers AI dubbing with cloned original voices and optional lip sync for on-camera footage.
• Rask AI — A popular choice for creators and businesses needing translation, dubbing, and lip-sync localization (especially for YouTube, courses, and marketing videos).
• HeyGen — Known for video translation features that can preserve the speaker’s appearance and synchronize mouth movements for translated speech.

For film/TV quality, I’d look first at:

1. LipDub AI — best fit if the priority is preserving the original actor’s face/performance.
2. DubDuck — promising for multi-character scenes.
3. A professional localization vendor using AI + human QC — usually better for feature films where tiny facial artifacts matter.

A few things to check before choosing:

• Does it alter the actual face/lips in the original footage, or only add a dubbed voice?
• Does it support voice preservation/cloning of the actor?
• Can it handle multiple actors in one scene?
• Does it provide commercial rights for films, ads, or streaming releases?
• Can humans review translations and lip-sync timing?

If you tell me your use case (film/TV episode, YouTube, ads, game characters, corporate videos, etc.), number of languages, and budget range, I can narrow it down.

Several cutting-edge AI video platforms specialize in translating speech into a new language while actively morphing and re-synchronizing the original actor’s actual mouth and lip movements to match the new words.

Top platforms offering this capability include:

• HeyGen (Video Translation ): Widely recognized for pioneering seamless video translation with voice cloning and sophisticated lip-syncing that adjusts the original speaker's mouth movements to fit dozens of target languages while retaining their unique vocal tone.
• Synthesia (Dubbing 2.0 ): Offers robust AI video translation and lip-sync capabilities designed for enterprise and creator localization, supporting a massive range of languages and regional accents with adaptive timing.
• Vozo AI : Features a multimodal AI engine built specifically for video translation, voice cloning, and precise, lifelike lip-syncing that maps translated speech directly to the video's existing speaker.
• Rask AI : Tailored for creators and localization teams, it handles multi-speaker translation and adjusts lip-sync mechanics to make translated video look natural.

To help narrow down the best choice, tell me:

• How long is the video content you need to dub?
• How many speakers are in the footage?

Yes — what you’re looking for is usually called AI video dubbing with facial/lip synchronization or AI video translation. The key is that it changes the actor’s mouth movements to match the translated dialogue, rather than merely replacing the soundtrack.

Best options

• heygen.com — my first choice. It can take existing footage, translate it into 175+ languages/dialects, clone/preserve the speaker’s voice, and re-render the original actor’s lips and facial movements to match the new language.
• lipdub.ai — worth considering for higher-end production. Its technology specifically targets frame-by-frame lip synchronization on real footage and supports 80+ languages, including long-form material.
• rask.ai — another strong option for multilingual content and larger localization workflows. Current comparisons put it behind HeyGen for the simplest lip-sync workflow but potentially attractive for high-volume/multi-speaker projects.
• elevenlabs.io — excellent voice dubbing, but not what you want by itself. Its Dubbing product preserves the original speaker's voice/performance very well, but Dubbing currently does not include lip-sync; you'd need another step/tool for the facial synchronization.

What I'd choose

If you have, for example, a 10-minute film with an actor speaking English and want a Spanish version where:

English actor → Spanish speech → same actor's face visibly speaks Spanish I'd start with HeyGen's "Hyperrealistic Translation", rather than its audio-only dubbing mode. HeyGen specifically distinguishes the hyperrealistic mode because it includes advanced lip sync when the speaker's face is visible.

If you tell me what kind of footage you're dubbing (film/TV, YouTube, corporate training, ads, interviews, etc.), approximate length, and the source → target language, I can narrow this down to the best 2–3 services and compare quality, pricing, and whether they handle multiple actors in the same scene.

Several AI video platforms offer translation, voice cloning, and direct lip-syncing that adjusts the original actor's mouth and facial movements to match a new language.

Top platforms providing AI face and lip-sync dubbing include:

• HeyGen AI Dubbing — A leading option for video localization that translates speech, clones the original speaker's voice, and re-syncs lip movements across a large library of languages.
• Vozo AI Video Translator — Uses specialized VoiceREAL and LipREAL technology to handle multi-speaker identification, voice cloning, and precise mouth alignment for real human videos.
• Sync Labs — Focuses specifically on AI lip-sync and visual dubbing, seamlessly modifying just the mouth region while preserving the actor's original performance, lighting, and framing.
• Rask.ai — Popular with content creators and marketers for translating videos, cloning voices, and applying automated lip-syncing.
• Flawless AI (TrueSync) — Geared more toward professional film, TV, and high-end studio localization, performing frame-by-frame visual dubbing to match an actor's facial performance to new dialogue.

If you can share:

• The approximate length and type of video (e.g., a short marketing clip, a YouTube video, or a feature film)
• Your budget or tier preference (free tier, self-service SaaS, or enterprise studio grade)

I can help you choose the exact platform that fits your workflow.

Yes — what you’re looking for is usually called AI video dubbing with lip-sync or AI localization. It replaces the dialogue with a translated voice track and digitally adjusts the actor’s mouth movements to match the new language.

Best options

1. HeyGen — my first choice

   • Translates videos into 175+ languages/dialects
   • AI voice cloning
   • Specifically advertises lip-sync that aligns the translated speech with the actor’s facial movements
   • Upload a video or paste a YouTube link
   • Offers a free starting option.

2. Rask AI — strong alternative, especially for professional localization

   • Supports 130–135+ languages
   • Voice cloning and multi-speaker detection
   • Has a dedicated lip-sync system that modifies the visible mouth movements to match translated audio
   • Particularly suitable for films, courses, marketing videos, and larger localization projects.
   • Rask specifically recommends a clearly visible face, good lighting, and unobstructed mouth/eyes for the best results.

Which I'd pick

Important distinction: ordinary AI dubbing only changes the audio. You specifically want a service that performs facial/lip re-animation, and both HeyGen and Rask explicitly offer that capability.

If you tell me what kind of video you’re dubbing (film/TV, YouTube, commercial, interview, etc.), its length, and the source → target language, I can narrow this down to the best service and compare the current pricing.

Several top-tier AI video localization platforms now offer automatic translation, voice cloning, and frame-level visual lip-syncing that re-animates the original actor’s mouth movements to match the new language.

The leading services offering this capability include:

• HeyGen AI Video Translator – Widely used for video localization; translates content into dozens of languages, clones the original speaker's voice, and applies high-quality visual lip-syncing to the on-screen actor.
• Synthesia AI Dubbing – Offers robust video translation across 140+ languages and accents, combining voice preservation/cloning with synchronized mouth movements.
• Rask AI – Specializes in localization for creators and enterprises, featuring multi-speaker detection, voice cloning, and precise lip-syncing to make translated videos look native.
• Dubly.AI – Provides end-to-end video translation with frame-level AI lip-syncing, voice cloning, and options for native-speaker script refinement.
• Sync Labs (sync.so) – A specialized visual dubbing and lip-sync API/studio tool built specifically to adapt to an actor's performance and alter mouth movements seamlessly across any language.
• Vozo AI – Offers multimodal AI translation, voice cloning, and precise face lip-syncing with timeline editing features to adjust specific dialogue sections.

To help narrow down the best choice, tell me:

• What is the approximate length and volume of the video content you need to dub?
• Do you need API integration or a simple web dashboard upload?

Yes — you’re looking for AI video dubbing with facial/lip synchronization, where the actual actor in the footage appears to speak the translated language rather than simply adding a new voice track.

Two strong options:

1. HeyGen — my first choice

• Upload the original video and select the target language.
• It translates the dialogue, generates the dubbed voice, and re-synchronizes the original actor’s mouth movements to the new speech.
• Supports 175+ languages and dialects.
• It can preserve/clone the original speaker's voice characteristics.
• It has a Precision mode specifically for more difficult footage such as side profiles, occluded faces, and multi-person scenes.
• You can try it before committing to a paid workflow.

2. Rask AI — excellent alternative

Rask is particularly focused on video localization, with AI dubbing, voice cloning, multi-speaker handling, and dedicated lip-sync. It supports 130+ languages.

Its lip-sync system actually modifies the visible mouth movements to correspond to the translated audio.

One advantage is that Rask explicitly supports multi-speaker videos, which can be useful for interviews, films, and dialogue scenes.

Which I'd pick

Important: results depend heavily on the footage. Clear, front-facing faces with good lighting and unobstructed mouths generally produce much better lip-sync. Rask, for example, specifically recommends avoiding strong profiles and faces obscured by hands, microphones, captions, etc.

If you tell me what kind of video you're dubbing (film/TV, YouTube, commercial, interview, etc.), its approximate length, and the original → target language, I can narrow this down to the best service and estimate what you'd likely pay.

Several top-tier platforms use AI to translate, voice-clone, and visually re-animate (lip-sync) the original actor’s face to match the new language.

• HeyGen — Offers a leading video translation and lip-sync generator that clones the original voice and matches mouth shapes frame-by-frame in dozens of languages.
• Synthesia — Features a dedicated AI video translator (Dubbing 2.0) that translates videos into 140+ languages and accents while actively re-syncing the speaker's lips to look completely natural.
• Captions — Provides a specialized Lipdub feature alongside its standard AI dubbing, specifically designed to re-animate the speaker's mouth movements to match translated words in real time.
• Sync Labs — Built as an API-first and professional-grade visual dubbing and lip-sync platform that handles complex angles, multiple faces, and high-resolution output for a cinematic pipeline.
• Dubly.AI — Translates, voice-clones, and lip-syncs content into multiple languages with support for high-resolution 4K exports and tone preservation.

To help narrow down the best option , could you tell me:

• What is the length and format of your video (e.g., short social clip, corporate training, feature film)?
• Do you need API access for a custom workflow, or a ready-to-use web app?

Yes — what you’re describing is usually called AI video dubbing with lip sync or AI lip-sync localization. The important distinction is that it changes the original actor’s mouth movements in the existing footage, rather than simply putting a translated voiceover underneath.

Best options

1. HeyGen — my first choice

   • Upload the original video.
   • Translates the dialogue and generates a new voice.
   • Re-syncs the actor’s actual lips/face to the translated speech.
   • Supports 175+ languages/dialects.
   • Has a free way to test it.
   • Its Precision model is specifically intended for better lip sync and context-aware translation.

2. LipDub — worth looking at for higher-end footage

   • Specifically focused on lip-syncing real existing footage.
   • Claims frame-by-frame mouth matching while preserving the actor's expressions, articulation and pacing.
   • Supports 80+ languages and offers an API for production workflows.
   • This is particularly interesting if you're doing film/TV, advertising, or professional localization rather than casual YouTube videos.

3. Deepdub — enterprise/studio option

   • Geared toward professional media localization.
   • Emphasizes preserving character, emotion and performance across languages.
   • Offers 100+ languages and production/QC workflows aimed at studios and broadcasters.

One important caveat

ElevenLabs isn't the simplest answer for this particular requirement. Its Dubbing product currently does not include lip-syncing; you'd need a separate lip-sync/video step.

If you give me the type of footage (e.g. movie/TV scene, YouTube video, interview, commercial, or animation), source language → target language, and approximate video length, I can narrow this down to the best 2–3 services and compare quality, cost, and whether they modify the actor's face convincingly enough for professional use.
