What each platform means by a language
Two products both say they support your target language, and they are describing different jobs. One will have a stock synthetic voice read a translated script. The other will reproduce the original presenter's own voice speaking that language, and move their mouth to match. Everything below was read from the vendors' own pages on 12 August 2026.
| Capability | HeyGen | Synthesia | Rask |
|---|---|---|---|
| Languages claimed | 175+ | 80+ | 32 |
| Clones original speaker | Voice cloning | Tier dependent | Yes, core feature |
| Lip-sync to new audio | Not listed | Not listed | Creator Pro |
| Translation available from | Creator $29 | Enterprise | Free trial |
| Script proofread step | Pro $49 | Not listed | Creator Pro |
| Free allowance | 3 videos | 10 min/mo | 3 min total |
| Entry paid | $29/mo | $19/mo | $33/mo |
| Minutes included | 600 credits | Credits | 300 per year |
| Overage per minute | Credit based | Credit based | $3 stated |
The language count is the least useful number on the page
HeyGen lists 175+ languages and dialects on its Creator tier at $29. Synthesia lists 1-click translation into 80+ languages at Enterprise. Rask lists 32. Ranked on that column alone, Rask finishes last and the ranking is meaningless, because Rask's 32 describes cloning a specific human voice into another language while the larger numbers describe the availability of stock synthetic voices.
Both are legitimate products. They are simply not substitutes:
- Synthetic voice localisation suits content where the presenter is a device rather than a person. Training modules, product explainers, anything with a stock avatar already. Nobody expects the narrator to be a specific individual, so a different voice per language costs nothing in credibility.
- Speaker-preserving dubbing is required when the person on screen is the point. A founder, an instructor with a following, a spokesperson, a talking-head channel. Swap that voice for a stock one and you have replaced the thing the audience came for.
The diagnostic question: if a viewer who knows the presenter watched the localised version, would anything feel wrong? If yes, you need the cloning-and-lip-sync category and the language count is a secondary filter applied within it. If no, take the widest language coverage you can afford.
Dubbing is priced per minute, and the minutes are annual
Avatar platforms sell credits. Dedicated dubbing platforms sell minutes, and the difference makes dubbing the one part of this market where cost is genuinely computable in advance.
Rask includes 300 minutes on Creator, 1,200 on Creator Pro and 6,000 on Business. Those allowances are per year, not per month, which is easy to misread on a page displaying a monthly price beside them. Creator at $33 a month is $396 billed yearly for 300 annual minutes, so the effective rate is around $1.32 per localised minute. Beyond the allowance, Rask states $3 per extra minute on Creator Pro and Business.
That $3 figure is the most useful number in this article, because it is a real published rate rather than a credit conversion, and it gives you a way to sanity check any localisation budget. A hundred minutes of overage is $300. A course library of forty ten-minute modules localised into three languages is 1,200 minutes, which lands squarely in Creator Pro territory and would be ruinous as overage.
And the annual billing pattern repeats here. Rask's $33, $78 and $500 assume yearly payment, exactly as Synthesia's $14 and $59 do. This is close to universal in the category now, so set every pricing page to the same billing term before comparing anything, and treat a headline monthly figure as an annual-commitment figure until you have checked.
Lip-sync is a tier, not a feature, and it is the one that sells the illusion
Translated audio over unchanged footage reads as dubbed. It is watchable, audiences accept it, and for internal training it is entirely sufficient. Lip-sync is what makes localised video read as native, and it sits higher up the price list than most buyers expect.
Rask places preserve speaker identity with lip-sync on Creator Pro at $78 a month, alongside control over translation and speech accuracy. Its entry Creator tier at $33 covers translating a single video into a few languages without that step. So the gap between acceptable and convincing is roughly $45 a month on this platform, and it is worth understanding which side of it your content needs before choosing a tier.
ElevenLabs approaches localisation from the audio side, with automatic dubbing, a Dubbing Studio and a Productions service across its tiers, and its Starter plan at $6 a month is the cheapest entry to commercially licensed cloned-voice output in this comparison. If your workflow already separates audio from picture, pairing an audio-first dubbing pass with your existing edit is often cheaper and more controllable than a single platform doing both.
Also worth pricing: Camb.ai for languages the larger platforms cover thinly, Colossyan which includes 15 auto translations a month on its free tier, and Vidnoz which places video translation on its Business tier at $56.99. For enterprise localisation pipelines, AI Studios and Elai both build around multi-language training output.
Which to choose, by what the video is
A named person whose audience knows them: Rask Creator Pro at $78. Speaker identity preserved with lip-sync is the specific capability that keeps a personal brand intact across languages, and 1,200 annual minutes covers a substantial channel. Budget $3 a minute beyond it.
Stock-avatar training content going wide: HeyGen Creator at $29. 175+ languages and dialects at the entry paid tier is the widest coverage here by a distance, and the translation proofreading step on Pro at $49 is what prevents a mistranslation becoming a re-render across a whole library.
Audio-led workflows, podcasts and voiceover: ElevenLabs Starter at $6. The cheapest commercially licensed cloned-voice output in this group, with dubbing tools attached, and it slots into an existing edit rather than replacing it.
Enterprise procurement with an approved-vendor list: Synthesia. 1-click translation into 80+ languages sits at Enterprise, so price it there rather than from the advertised entry tiers, and use the free 10 minutes a month to build the internal case.
Testing before committing anything: Colossyan. 15 auto translations a month on a free tier is the least expensive way to find out whether synthetic-voice localisation is good enough for your material, which is the question that decides everything else on this page.

Frequently asked questions
Which AI tool dubs video into the most languages?
HeyGen lists 175+ languages and dialects on its Creator tier at $29 per month, the widest coverage in this comparison. But the number describes availability of synthetic voices, not preservation of the original speaker. Rask lists 32 languages and clones the actual speaker's voice into them with lip-sync. If the person on screen matters to your audience, the smaller number is the more capable product for your purpose.
Can AI dubbing keep the original speaker's voice?
Yes, and it is the main thing separating dedicated dubbing platforms from avatar platforms. Rask clones the speaker's voice across 32 languages and adds lip-sync on its Creator Pro tier at $78 per month, where it also lists control over translation and speech accuracy. ElevenLabs offers cloned-voice output with dubbing tools from its Starter tier at $6 per month, approaching the same job from the audio side rather than the video side.
How much does AI video dubbing cost per minute?
Rask publishes the clearest figure at $3 per extra minute beyond the plan allowance on Creator Pro and Business. Its included minutes are annual rather than monthly: 300 per year on Creator, 1,200 on Creator Pro and 6,000 on Business. Creator at $33 per month billed yearly works out around $1.32 per localised minute within the allowance. Avatar platforms selling credits rather than minutes cannot be converted to a per-minute rate reliably.
Is lip-sync worth paying extra for?
It depends entirely on whether the presenter is the point of the video. Translated audio over unchanged footage reads as dubbed, which audiences accept and which is fine for internal training. Lip-sync is what makes a localised video read as native, and it matters when a founder, instructor or spokesperson has a relationship with the audience. On Rask the step from translation to lip-synced speaker preservation is roughly $45 per month, from Creator at $33 to Creator Pro at $78.
Why do dubbing prices look cheaper than they are?
Two reasons, and both recur across the category. First, headline monthly prices frequently assume annual billing: Rask's $33, $78 and $500 are billed yearly, as are Synthesia's $14 and $59. Second, included minutes on dubbing platforms are often annual allowances displayed next to a monthly price, so 300 minutes beside $33 per month reads as monthly and is not. Set every pricing page to the same billing term and check whether allowances are monthly or yearly before comparing.
