I need a dubbing service that matches the speaker's lip movements and does not look out of sync.

If you need dubbing that doesn’t look like a voiceover pasted on top, look for a service with AI lip-sync / facial re-animation or professional lip-sync dubbing (not just translation + voice replacement). These are some options:

Service	Best for	Lip-sync capability
HeyGen	Creators, marketing videos, talking-head content	AI lip sync, multilingual dubbing, voice preservation, and multi-speaker syncing features.HeyGen
Adobeadobe.com	Professional creative workflows	Firefly’s dubbing tools include voice matching and lip-sync options for translated video.Adobe
ElevenLabs	Natural-sounding AI voices and localization	Known for voice cloning and dubbing workflows; combine with a lip-sync stage if you need the mouth movements altered.
Gotham Lab	Films, TV, professional human dubbing	Traditional frame-accurate lip-sync dubbing with voice actors and post-production.Gotham Lab
DubVid	Quick AI dubbing for social/video creators	Offers AI lip-sync dubbing that adjusts mouth movements to match translated audio.DubVid
SpeakSwap	Multilingual creator content	Provides AI dubbing with speaker/face matching and smart lip sync.SpeakSwap

For the most natural result, choose based on your footage:

• Single person speaking to camera (YouTube, courses, ads): HeyGen, Adobe Firefly, DubVid, or similar AI lip-sync tools.HeyGen+2
• Movie, documentary, TV, or actor performance: use a professional dubbing studio with human voice direction and frame-by-frame sync.Gotham Lab
• Important brand/founder videos where the person must still feel like themselves: use voice preservation/cloning plus lip-sync, not a basic translated voice track.Adobe+1

Before committing, I’d test with a 30–60 second clip containing:

• clear front-facing speech,
• visible mouth movements,
• several words with P/B/M/F sounds (harder lip shapes),
• natural pauses and expressions.

Those clips reveal sync quality much better than a simple sentence.Vivideo

If you tell me your use case (YouTube, film, course, ads, corporate, anime, etc.), target languages, and whether you want to keep the original speaker’s voice, I can narrow it down.

For natural-looking lip-sync dubbing, I’d start with HeyGen. It specifically resynchronizes the speaker’s mouth movements to the translated audio and supports 175+ languages.HeyGen

• HeyGen — strongest fit for talking-head videos and visible lip movement.
• Rask AI — also offers voice cloning and lip-sync across 135+ languages.Rask
• ElevenLabs — excellent voice quality, but its dubbing is primarily audio-focused rather than automatically altering mouth movements.HeyGen

If your priority is specifically “you can't tell it's dubbed,” choose a service with actual facial/lip resynthesis rather than audio-only dubbing.

To get a dubbing service that actually matches mouth movements and avoids the awkward "badly dubbed martial arts movie" effect, you need AI video translation tools with built-in visual lip-syncing . Traditional dubbing only replaces the audio track, but these tools actually re-render or morph the speaker's mouth frame-by-frame to match the new phonemes of the translated language.heygen.com+2

The top platforms specializing in realistic, in-sync AI dubbing include:

• HeyGen: Widely considered a gold standard for talking-head and presenter videos. It handles translation across 175+ languages, clones the original speaker's voice, and executes precise lip-syncing so the mouth naturally matches the new audio.heygen.com+2
• Rask AI: Built specifically for content creators, educators, and marketers looking to localize long-form or short-form videos. It translates into 130+ languages, offers voice cloning, and features a dedicated Lip-Sync mode that maps out mouth movements after you review and tweak the translated transcript.rask.ai+2
• Magic Hour AI: Emerged as a powerful all-in-one generative video and lip-sync suite. It handles fast speech exceptionally well, keeping mouth movements aligned with the audio track even in more dynamic footage.reddit.com
• Sync (Sync Labs): A heavy-duty professional visual dubbing platform powered by advanced models (like Sync 3 and Lipsync 2 Pro). It handles difficult camera angles, low light, quick dialogue, and multiple faces, and integrates directly into professional workflows like Adobe Premiere.youtube.com

To help narrow down the best fit, tell me:

• What type of video is it? (e.g., a talking-head YouTube video, a corporate training course, a cinematic film)
• How long is the footage, and what languages are you translating between?

Yes — if your priority is the dubbed audio actually matching the speaker’s mouth movements, you want a service with AI video lip-sync, not just voice dubbing.

My top picks

• heygen.com — Best overall for your requirement. It specifically combines translation, voice cloning, and lip-sync, and is designed to modify the visible mouth movements to match the translated speech. It supports 175+ languages/dialects.HeyGen
• rask.ai — Strong alternative. Its dedicated Lip-Sync feature adjusts mouth movements to the translated audio and supports 135+ languages. It also handles multiple speakers and voice cloning.Rask Help+1
• elevenlabs.io — Excellent voices, but not my first choice for this particular need. Its Dubbing product preserves voice, emotion, timing, and tone, but lip-sync is not currently included in Dubbing itself. Its managed Productions service can synchronize timing/visible mouth movements, but explicitly says perfect lip-sync isn't guaranteed.ElevenLabs+1
• deepdub.ai — Best for professional/enterprise localization. It emphasizes production-grade dubbing, frame-accurate timing, voice continuity, and Hollywood/media workflows.Deepdub

If this is for a normal talking-head video, course, interview, YouTube video, or social-media clip, I'd start with HeyGen or Rask. The key distinction is that they don't merely replace the audio—they actually perform visual lip synchronization, which is what prevents the "voice is saying one thing while the mouth is doing another" effect.

If you tell me your video length, target language(s), and whether you need to preserve the original speaker's voice, I can narrow it down to the best service and approximate cost.

To get a dubbed video where the speaker's mouth matches the new audio without looking awkwardly out of sync, you need AI video translation and visual dubbing tools that actively remap or re-synthesize the mouth shapes (visemes) to fit the translated words.

Top platforms specialize in realistic lip-syncing for dubbing:

• HeyGen : Excellent for video translation and localization. It translates your source video into dozens of languages, clones the original speaker's voice tone, and features a dedicated lip-sync toggle that actively reshapes mouth movements to match the new language seamlessly.heygen.com+2

• ElevenLabs : Widely known for ultra-realistic voice cloning and dubbing workflows, ElevenLabs integrates tightly with various visual sync pipelines to ensure that translated dialogue retains the emotional cadence and pacing of the original speaker.

If you want to narrow this down, let me know:

• Are you translating an existing video of a real person , or generating a video from a still photo/avatar?
• What is the source language and the target language you need?

If you need a dubbing solution that actually reshapes or matches mouth movements to avoid that unnatural "badly dubbed martial arts movie" look, standard audio translation won't be enough. You need AI video translation with integrated visual lip-syncing.
