Seven AI tools that translate and dub your videos into other languages, from HeyGen and ElevenLabs to Rask, Synthesia, Vozo, Perso and YouTube's free auto-dubbing, with prices, languages, voice cloning and lip sync.
HeyGen is the best AI video translation tool for most creators: it translates into 175+ languages and dialects in your own voice, syncs your lips to the new audio, and handles up to 10 languages in one pass, from $29 a month.
ElevenLabs gives you the most natural cloned voices for the money, with dubbing in 90+ languages from $6 a month, but it doesn't sync lips.
Rask and Synthesia add lip sync and multi-speaker detection, though both charge extra for it: Rask puts lip sync on its $99 Creator Pro plan, and Synthesia's uses twice the credits.
Vozo is the pick if your video has text on screen, since its Visual Translate feature translates captions and graphics too.
YouTube's auto-dubbing is free for every channel in 27 languages, but you can't edit the dubs.
We looked at how natural the translated voice sounds and whether it keeps the speaker's own voice, lip sync quality, how many languages each tool covers, multi-speaker handling, whether you can edit the translated script before rendering, and what a month of regular dubbing costs.

HeyGen is an AI video platform, and its video translation tool dubs an existing video in your own voice and matches your lips to the new language.
What works: It covers 175+ languages and dialects, keeps the speaker's voice, and aligns lip movement to the translated audio. You can send one video into up to 10 languages at once, paste a YouTube link instead of uploading, and add a brand glossary so product names and protected terms come out right. It also writes subtitles and offers an API. The free plan includes three videos a month, and Creator ($29 a month, or about $24 billed yearly) removes the watermark and handles 30-minute translations.
What doesn't: Lip sync on the free plan is a limited trial, and reviewing and editing the translated script before rendering starts on the $49 Pro plan. HeyGen bills translation in credits that vary by model and video length, so it's hard to predict a month's cost, and unused credits roll over for only one month.
Best for: Creators and marketers who want on-camera videos that look and sound native in many languages.
ElevenLabs is an AI voice company, and its Dubbing tool translates a video's speech while cloning each speaker's voice.
What works: It dubs into 90+ languages, detects each speaker, and lets you set how closely the dub matches the original voice. Dubbing v2, released in May 2026, translates audio directly so tone and emotion carry over, and it reached the API in August 2026 with better handling of several speakers and background audio. Automatic dubbing costs 2,000 credits a minute, so the $6 Starter plan (30,000 credits) covers about 15 minutes, and Creator ($22) about 60. The API is available on every plan.
What doesn't: Dubbing doesn't sync lips, so it suits voiceover, podcasts and videos where the speaker isn't on camera better than talking-head footage. Free dubs carry a watermark, and the older Dubbing Studio editor is in maintenance mode.
Best for: YouTubers, podcasters and course makers who care most about how the voice sounds.
Rask AI is a dedicated video translation tool with dubbing, voice cloning and lip sync.
What works: It translates into 135+ languages, clones voices in 32 of them, and detects multiple speakers so each keeps a distinct voice. You can edit the translated text before rendering, keep a translation dictionary for terms, import and export SRT subtitle files, and use an API. A free trial gives you three minutes without a card, and Creator costs $39 a month ($28 billed yearly) for 25 minutes.
What doesn't: Lip sync is listed only from the $99 Creator Pro plan (100 minutes), and its enhanced lip sync uses three minutes of your allowance for every minute of video. Monthly plans don't roll unused minutes over.
Best for: Interviews, panels and other videos with more than one speaker.
Synthesia is best known for AI avatar videos, and its AI dubbing tool translates videos you've already shot.
What works: It clones every speaker's voice, syncs lips, detects multiple speakers, and lets you review and edit the transcript with free retranslation. Dubbing 2.0, released in July 2026, rebuilt its lip sync to drift less across cuts and in scenes with several people, and added glossary support. The free plan includes 10 dubbing minutes a month, and Starter costs $29 a month ($18 billed yearly) for up to 16 minutes. It accepts 4K uploads and YouTube links.
What doesn't: Free videos carry a watermark, lip sync uses twice the credits, and self-serve plans cover 70+ dubbing languages, while the full list of 140+ is for Enterprise.
Best for: Teams that want to test dubbing on a few videos a month for free.
Vozo is an AI video localization tool that translates speech and the text that appears in your video.
What works: It dubs from 111 source languages into 165 target languages, with voice cloning and lip sync on files up to 60 minutes long at up to 4K. Its Visual Translate feature, launched in beta in March 2026, translates on-screen text like captions, titles and graphics. Creator costs $29 a month for 150 points, which works out to about 50 dubbing minutes or 15 lip-sync minutes.
What doesn't: Free trial points expire after seven days, points only work while you're subscribed, and you need Creator to remove the watermark. Lip sync costs about three times as much as dubbing alone.
Best for: Tutorials, explainers and ads with text on screen.
Perso AI is a dubbing tool from South Korean software company ESTsoft.
What works: It syncs lips in 74 languages and lets you edit each speaker and export each one's audio separately. Starter costs $6.99 a month for seven minutes, including two minutes of lip sync, and Creator ($29) includes 40 minutes with 13 of lip sync. In 2026 it added audio separation and the option to buy extra dubbing time.
What doesn't: Starter caps each video at three minutes, and you get a single free generation when you sign up.
Best for: Short-form creators who want lip-synced clips on a small budget.
YouTube now dubs videos automatically, and in February 2026 it said the feature is available to everyone in 27 languages.
What works: It costs nothing, and eligible channels get it on by default (others can turn it on in Advanced settings). Expressive Speech, which keeps more of your tone, works in eight languages: English, French, German, Hindi, Indonesian, Italian, Portuguese and Spanish. Viewers can switch audio tracks, and you can review dubs before they publish or turn the feature off. YouTube says more than 6 million viewers a day watched at least 10 minutes of auto-dubbed content in December 2025.
What doesn't: You can't edit the dubs, lip sync is only a pilot for select channels, and videos over 120 minutes, music-heavy videos and videos with copyrighted material aren't eligible. It only works on YouTube, so you can't take the dubbed audio elsewhere.
Best for: YouTube creators who want to reach other languages without paying for a tool.
Only if the speaker's face is on screen for long stretches. For voiceover, screen recordings, animation and B-roll-heavy videos, a dubbed voice with no lip sync works fine, and tools like ElevenLabs are cheaper for it. For talking-head videos, ads and interviews, mismatched lips are easy to notice, so a tool with lip sync like HeyGen, Rask, Synthesia or Vozo is worth the extra cost. Most of them charge more for lip sync than for dubbing alone.
HeyGen, for most creators. It translates into 175+ languages and dialects in your own voice with lip sync, from $29 a month. ElevenLabs is the better pick if you only need the voice, from $6 a month.
YouTube's auto-dubbing is free for videos on YouTube in 27 languages. Synthesia's free plan includes 10 dubbing minutes a month with a watermark, and HeyGen's free plan includes three videos a month.
Yes. HeyGen, ElevenLabs, Rask, Synthesia, Vozo and Perso all clone the original speaker's voice, so the dub sounds like you speaking another language.
HeyGen, Rask (from Creator Pro), Synthesia, Vozo and Perso sync lips to the translated audio. ElevenLabs' Dubbing doesn't, and YouTube's lip sync is a pilot for select channels.
Yes. Viewers see that a video is auto-dubbed, and they can switch back to the original audio track.
