What AI dubbing actually costs per minute

One dubbed minute runs from about $0.16 to $2.34 across the tools listed here, at each vendor's best published annual rate — and the ordering is the opposite of what you would guess. Rask AI, the only dedicated dubbing product on the list, is the most expensive way to buy a lip-synced minute at $0.78, against $0.24 for the same job inside a HeyGen Creator subscription. Buy them as identical throughput and the gap is plain: 1,200 lip-synced minutes a year costs $288 on HeyGen and $936 on Rask.

Quick verdict

Review type: Public-data comparison, not hands-on testing. Every rate below is transcribed from the vendor's own pricing page, credits guide or help centre, checked 15 September 2026. The per-minute conversions and every percentage are CartSignal arithmetic and are labelled where they appear.

Short answer: If you already pay for an avatar-video tool, dub inside it. A dubbing specialist sells you a bigger, more flexible pool of minutes — not a cheaper minute.

Disclosure: ElevenLabs has an affiliate redirect on this site, disclosed on its profile. HeyGen, Synthesia, Speechify, Murf and Rask AI carry no affiliate relationship in the local CartSignal data, and the vendor links below are plain official URLs. Nothing in the ranking is affected by either.

"Dubbing" is two different products at two different prices

Before any rate makes sense, the word has to be split. Every tool here takes a finished recording and gives it back speaking another language. Only some of them move the speaker's mouth to match.

ElevenLabs is the clearest case, because it says so plainly. Its dubbing product guide states verbatim: "At the moment, ElevenLabs does not offer lip syncing as part of Dubbing." You can feed it a video — the website accepts files up to 2 GB and 180 minutes — and it returns translated audio over the original picture, in 90+ languages. That is a genuinely useful product for podcasts, narration and voice-over-b-roll. It is not the same product as a talking-head video whose lips match the new language, and comparing the two on price alone is how most "cheapest AI dubbing" lists go wrong.

So the table below carries a lip-sync column, and the honest gaps are marked as gaps.

Cost per dubbed minute, at each vendor's best annual rate

Plan prices and credit rates are the vendors' own. The dollars-per-minute column is CartSignal's arithmetic: plan price divided by credit allowance, multiplied by the published credits-per-minute rate.

Tool and modePublished rateCost per dubbed minuteLip sync

Murf Dub, pay as you go — Automated2 credits per minute per language, $1 per credit$2.000Not documented
Rask AI Creator Pro annual — Enhanced lip sync1 minute of video = 3 minutes$2.340Yes

The floor-to-ceiling span is about 15x, and about 12.8x if you stop before Rask's Enhanced mode. Two caveats sit on this table and neither is small. First, these are list prices for different products — a lip-synced minute and an audio-only minute are not substitutes, and nothing here is a judgement about how good any vendor's output is. Second, monthly billing moves several rows sharply: Synthesia Starter billed monthly is $29 for 1,200 credits, which turns its lip-synced minute from $0.745 into $1.208, and Rask Creator billed monthly is $2.40 a minute against $1.32 annually.

The Speechify asterisk

Speechify's Studio pricing page publishes exactly one dubbing rate — 3 credits per second — and no separate lip-sync rate. Its video dubbing editor page markets "precise lip-syncing capabilities", and its dubbing page advertises "Dub Content in 60+ Languages". Whether that lip sync is included at the 3-credit rate is not establishable from public data, so CartSignal does not claim the cheapest minute on this page is also the cheapest lip-synced one. If it is, Speechify undercuts everything here. Ask before you buy on that basis.

The specialist premium

The result worth arguing with is that the purpose-built tool is the expensive one. Rask AI sells dubbed minutes directly rather than in credits, which makes it the easiest product here to budget — Creator Pro is "$78/mo billed $936 yearly" for 1,200 minutes a year. That is $0.78 a minute with Standard lip sync, and Rask's own pricing page gives the multiplier for the better mode: "Standard Lip-sync: 1 minute of video = 1 minute. Enhanced Lip-sync: 1 minute of video = 3 minutes." So Enhanced is $2.34.

Held against HeyGen at matched throughput, with no credit conversion in the way:

1,200 lip-synced minutes a yearHow it is boughtAnnual cost
HeyGen Creator, billed annually600 credits a month ÷ 6 per minute = 100 minutes a month$288
Rask AI Creator Pro, billed annually1,200 minutes, pooled across the year$936

That is 3.25x for the same number of minutes. What the extra buys is real but it is not price: Rask's pool is annual and can be spent in any distribution, while HeyGen's is a monthly allowance with its own rollover rules, and Rask's API documents 130 destination languages against HeyGen's cap of 10 languages per job. If your localisation arrives as one big batch twice a year, the pooled minutes matter. If it arrives steadily, they do not.

Rask also contains the pattern this site keeps finding in credit ladders — it runs backwards at the top. Business billed annually is $6,000 for 6,000 minutes, exactly $1.00 a minute, which is 28.2% more per minute than the Creator Pro tier beneath it. On monthly billing the two are identical at $1.50. Buying the bigger plan buys volume headroom and, on Business, $3.00-a-minute overage — not a discount.

Dub it, or regenerate it?

If the source is already an AI avatar video, you have a choice most buyers never price: translate the render you have, or generate a fresh one from a translated script. Both platforms that publish rates for each make dubbing the cheaper move.

PlatformGenerate a fresh minuteTranslate an existing minuteVerdict
Synthesia2 credits per second = 120 per minute25 without lip sync, 50 withDubbing is 4.8x or 2.4x cheaper
HeyGen4 credits/min on Avatar III Video Look, up to 48 on Avatar V4 audio only, 6 Speed, 10 PrecisionPrecision is 4.8x cheaper than Avatar V — but exactly ties Avatar III Video Look at 4 credits

HeyGen's tie is the useful oddity. Translating a video without lip sync and generating a completely new minute on its cheapest avatar model cost the identical 4 credits. So if your source is an avatar video and you still hold the script, regenerating in the target language is free relative to dubbing it, and gives you a clean render instead of a lip-sync pass. That only works when you own the script and the avatar; for filmed footage of a real person, translation is the only route. Both models' full rate cards are on the HeyGen vs Synthesia comparison.

The multiplier nobody puts on the pricing page

Dubbing bills per language, not per video. Murf's help centre is the most explicit about it: "2 credits are consumed for every minute of your file for each language selected." HeyGen allows up to 10 target languages per translation job, and charges for every one. So the quantity you are buying is source minutes × languages, and it grows much faster than people plan for.

Here is one realistic job — a ten-minute explainer into ten languages, which is 100 billed minutes:

ToolWhat the job costsAgainst the plan it sits on
Speechify Studio Creator$15.6218,000 of 345,600 credits — 5.2% of the year
ElevenLabs Pro annual, watermarked$27.50200,000 of 600,000 credits — a third of the month
Rask AI Creator Pro annual$78.00100 of 1,200 minutes — 8.3% of the year
Murf Dub, pay as you go$200.00200 credits bought outright
HeyGen Creator annual, Speed lip sync600 creditsExactly 100% of one month's allowance
Synthesia Starter yearly, with lip sync5,000 credits34.5% of the entire year's 14,500

Two things fall out. The same job is 12.8x dearer on Murf than on Speechify. And on the two avatar platforms, the plan allowance binds long before the price does — one ten-minute video, localised once, eats a whole month of HeyGen Creator or a third of a Synthesia Starter year. This is the same shape the best AI video tools ranking found in the generative lane: the sticker price is rarely the constraint.

Five traps in the small print

  • ElevenLabs charges to remove its watermark. Automatic dubbing is 2,000 credits a minute with a watermark and 3,000 without — a flat 50% surcharge on every minute. Its Dubbing Studio route is 5,000 and 10,000 respectively, up to 5x the automatic rate, for in-app editing on a product the docs describe as in maintenance mode.
  • Murf rounds up to the half minute. Its credits article states file durations are "rounded up to the nearest(subsequent) 30 seconds". A 31-second clip bills as 60 seconds — a 94% overcharge on short social cuts, and it applies per language.
  • Entry plans buy startlingly little. ElevenLabs Starter billed annually is 30,000 credits, which at 2,000 a minute is 15 dubbed minutes a month. Speechify Creator's 345,600 credits are 32 dubbed hours for the year. Check the allowance in minutes, not in credits.
  • Synthesia credits do not accumulate. Its credits guide says so directly: credits reset at the start of the billing period with no accumulation of unused credit. A localisation batch you postpone is a batch you pay for twice.
  • The cheapest mode may not survive your footage. HeyGen documents Speed mode as suited to front-facing video, and Precision as the mode that handles speaker switches, side-profile shots and facial occlusions. If your source is an interview, the honest planning rate is $0.40, not $0.24.

How to choose

  • Already paying for HeyGen or Synthesia? Dub there. You are almost certainly not going to beat $0.24 a lip-synced minute, and you avoid a second subscription.
  • Audio only — podcast, narration, voice-over-b-roll? ElevenLabs at ~$0.28 on Pro annual, or Speechify Studio at ~$0.156 if its allowance fits. Neither moves lips, and for these formats neither needs to.
  • Large, lumpy batches in many languages? This is the case Rask AI is actually built for — 1,200 pooled annual minutes and 130 destination languages, at a unit price you pay for knowingly.
  • Just testing? Synthesia's dubbing page offers a first free minute, and Murf Dub's free trial carries 200 credits — 100 automated dubbed minutes, watermarked and limited to one project.
  • Publishing into the EU? A dubbed video is synthetic media. Article 50 duties apply to you, not to your vendor — see labelling AI video and voice under the EU AI Act.

What this page does not establish

No audio or video was dubbed for this comparison, so there is no finding here about translation accuracy, voice likeness across languages, or how convincing any vendor's lip sync looks in motion — and those differences are very likely larger than the price differences. Three specific gaps are worth naming: whether Speechify's 3-credit dubbing rate includes lip sync; whether Murf Dub performs lip sync at all, since neither of its dubbing help pages mentions it; and what Murf's Quality Assured dubbing really costs, because the published rate of 62 credits a minute per language sits on an Enterprise plan with custom pricing and volume discounts, so the $62.00 that falls out of the $1 pay-as-you-go credit price is an upper bound rather than a quote. Per-character narration rates for the same vendors, which are a different meter again, are ranked on ElevenLabs alternatives.

FAQ

How much does AI dubbing cost per minute?

At each vendor's best published annual rate: about $0.156 on Speechify Studio Creator, $0.16 on HeyGen without lip sync, $0.24 with Speed lip sync, $0.275 on ElevenLabs Pro or Business, $0.372 on Synthesia Starter yearly without lip sync and $0.745 with it, $0.78 on Rask AI Creator Pro, and a flat $2.00 on Murf Dub. That is about 12.8x across the list, or 15x including Rask's Enhanced lip sync at $2.34.

Is a dedicated dubbing tool cheaper than dubbing inside a video tool?

No. Rask AI's cheapest lip-synced minute is $0.78 against HeyGen's $0.24. Bought as identical throughput — 1,200 lip-synced minutes a year — HeyGen Creator annual is $288 and Rask Creator Pro annual is $936, about 3.25x. The specialist sells a flexible annual pool and 130 destination languages, not a cheaper minute.

Does ElevenLabs dubbing do lip sync?

No. Its product guide says so verbatim. It takes video and returns translated audio in 90+ languages over the original picture, so the speaker's mouth still moves to the old language. Removing the watermark costs 50% more.

Is it cheaper to dub a video or regenerate it in the new language?

Dubbing, on both platforms that publish both rates. Synthesia generates at 120 credits a minute and dubs at 25 or 50, so dubbing is 4.8x or 2.4x cheaper. HeyGen translates without lip sync at 4 credits a minute, exactly what generating a fresh minute on Avatar III Video Look costs — so if you own the script and the avatar, regenerating is a free alternative there.

Does dubbing bill per language?

Yes. Murf states it outright, and HeyGen bills each of the up-to-10 languages in a job. A ten-minute video into ten languages is 100 billed minutes: $15.62 on Speechify Creator, $27.50 on ElevenLabs Pro annual, $78.00 on Rask Creator Pro annual, $200.00 on Murf — or the whole of one HeyGen Creator month.
