What is AI dubbing?

AI dubbing takes the audio track of an existing video and replaces it with a new spoken track in a different language, timed to roughly match the original speaker's mouth movements and pacing. The better tools try to preserve the original speaker's tone and delivery rather than flattening everything into one generic narrator voice. This is different from translation alone, a dubbing tool handles the actual voice generation and timing, not just the text.

Tools compared

Tool	What it is	Languages	Cost
ElevenLabs Dubbing Studio	AI dubbing built into the ElevenLabs platform, using a model the company calls Dubbing v2	90+ languages and accents, including Mandarin, Hindi, Japanese, Polish, Swedish, Vietnamese and French	Included on every plan from $5/month (Starter); extra dubbing minutes cost $4.91 (Starter), $2.70 (Creator) or $2.45 (Pro) each
Descript	Video editor with AI voice features, used by some teams for simple same-language dubbing or voiceover replacement rather than full multilingual dubbing	Primarily English voice generation, not a dedicated multilingual dubbing product	From $16/month (Hobbyist)

For genuine multilingual dubbing specifically, ElevenLabs is the clearest fit on this list: it's a purpose-built dubbing feature with per-minute overage pricing stated directly on its own site, rather than a general editor repurposed for the job. For voiceover tools as well, see the wider comparison for business video.

How ElevenLabs actually prices dubbing

Dubbing runs on the same credit system as the rest of your ElevenLabs plan. Your monthly credit allowance (10,000 free, 30,000 on Starter, 121,000 on Creator, 600,000 on Pro, as of October 2026) covers a mix of text to speech, dubbing and other generation. Once you go past your included dubbing minutes, ElevenLabs bills extra minutes separately: $4.91 a minute on Starter, dropping to $2.70 on Creator and $2.45 on Pro. For a 20-minute training video dubbed into three languages, that's 60 minutes of dubbed audio, which can get expensive fast on the Starter plan and is noticeably cheaper on Creator or above if dubbing is a recurring need.

A worked example

Say you have a 10-minute product demo and want it dubbed into Spanish, French and Arabic. That's 30 minutes of dubbed output. On the Creator plan at $2.70 a minute for overage, that's roughly $81 in overage charges on top of your $11 monthly plan (or $22 at the promotional first-month rate), assuming your included credits are already used elsewhere. Run the same math against your own video length and target language count before you commit, since the per-minute cost adds up quickly past a handful of languages.

Dubbing vs. subtitles: which actually serves your audience

Dubbing isn't always the right call just because it's available. Subtitles are cheaper, faster to produce, and easier to correct after the fact, a wrong word in a subtitle file is a one-line text edit, while a wrong word in dubbed audio means regenerating that section of speech. Dubbing earns its extra cost and effort specifically when your audience is likely to be doing something else while watching, driving, working with their hands, or when literacy in the written form of the target language is a genuine concern for your audience. For most internal training content where staff are sitting and watching attentively, subtitles alone often serve the purpose at a fraction of the cost and complexity. Save dubbing for content where someone genuinely needs to listen rather than read, a safety video playing on a job site screen, or a product demo meant to run unattended at a trade show booth. For Arabic and English, see the subtitles, dubbing and lip sync options.

Quality fixes you will actually need to make

• Product names and brand terms: AI dubbing frequently mispronounces names that aren't common words in the target language. Check every instance of your product name in the dubbed output.
• Numbers, prices and units: These often render incorrectly or awkwardly across languages, especially currency and measurement units that don't translate directly.
• Timing drift on longer videos: Dubbed audio can drift out of sync with on-screen action over a long video, even when it starts aligned. Spot-check the middle and end of the video, not just the opening.
• Tone on emotionally sensitive content: If the original video includes genuine enthusiasm, urgency or empathy, check that the dubbed version still carries it, rather than reading flat.

Budget time for a native speaker to review the dubbed output before it goes live externally. This is true of every tool on this list, not just the cheaper ones. If your dubbed video also needs new product shots or visuals rather than just a translated voice track, ElevenLabs' image and video tools sit inside the same account.

Build the native-speaker review into your actual production schedule, not as an optional extra step squeezed in if time allows. A reasonable rule of thumb is budgeting roughly the length of the video itself for a careful review pass, a 10-minute video needs about 10 focused minutes of a native speaker actually listening and checking against the source script, longer if the content includes technical or industry-specific vocabulary that's more likely to trip up the dubbing model. This guide explains when AI is enough and when to hire a native speaker.

Choosing which languages to dub into first

Don't default to dubbing into every language a tool supports just because the option exists. Start from your actual audience data, which languages do your current customers, trainees or site visitors actually speak, and dub into those first. A trades business with a largely Spanish-speaking crew gets far more value from one well-reviewed Spanish dub of a safety video than from ten languages dubbed thinly and never properly checked. If you genuinely don't know your audience's language breakdown, a quick survey of your current staff or customer base is a better starting point than guessing, since getting this wrong means spending credits and review time on languages nobody in your actual audience needs.

Dubbing a whole library at once, vs. one video at a time

If you have a backlog of existing training or product videos rather than just one new piece, dub them in a deliberate order rather than all at once: start with your highest-traffic or most frequently referenced video, confirm the quality and review process works well on that one, then move through the rest of the library. This catches process problems, a recurring mispronunciation, a tone mismatch, a timing issue, on a single video before you've spent the time and credits dubbing an entire library the same flawed way. Batch dubbing an entire library in one pass only makes sense once you've already validated the approach on a representative sample.

How does Blur Studio approach multilingual video?

For a one-off training video or demo, a dubbing tool like ElevenLabs is usually the right call, it's fast and the cost is predictable once you've run the math on minutes and languages. Where I get involved is when a business needs dubbing wired into a repeatable pipeline, say every new product video automatically gets dubbed into your top three markets and published, rather than someone manually running each video through a tool by hand.
