One video, ten languages,
dubbed and lip-synced by an agent
A video that works in one market usually needs a dubbing studio booking per language to reach the next nine, which is slow and expensive enough that most teams just subtitle instead. We build a dubbing pipeline that translates the script, generates a matched voice in each target language, and lip-syncs the result, with a native speaker reviewing every language before it ships.
The process today
A video that performs well in its home market usually just gets subtitled for everywhere else, because dubbing has meant booking a studio and a voice actor per language, which costs more and takes longer than most content calendars can absorb for more than one or two priority markets. The result is that most video content never gets a real local voice treatment, and subtitle-only versions underperform dubbed ones on platforms where autoplay starts muted or where literacy in the subtitle language is lower than spoken fluency.
The second cost is consistency: when dubbing does happen, it is often outsourced per language to different vendors, producing a different voice, tone and glossary choice in each market instead of one coherent brand voice.
The third is turnaround on anything time-sensitive, a product launch, a seasonal campaign, where a studio booking cycle per language means some markets get the video weeks after it matters.
None of this shows up as one dramatic failure. It shows up as a steady drag: AI video dubbing work that should take minutes stretching into a backlog item, a quality bar that holds on a quiet week and slips on a busy one, and a team that knows the fix is mechanical but never has a free afternoon to build it themselves.
What the agent does
The agent takes the source video and script, translates it for spoken delivery rather than literal text, keeping idioms and pacing natural in each target language, and generates a voice matched to the original speaker’s tone across up to 10 languages in one pipeline run. It adjusts lip-sync so the dubbed audio tracks the speaker’s mouth movement closely enough to not distract the viewer, which is the detail that makes dubbed content feel native rather than overlaid.
A glossary of brand terms, product names and anything that should stay untranslated is applied consistently across every language, so the same product is called the same thing everywhere it should be. Every language version then goes to a native speaker for review, checking meaning, tone and delivery, not just whether the translation is grammatically correct.
Typical integrations: your video editing or storage tool for the source file, and whatever platforms or ad accounts the dubbed versions are published to per market.
What stays with humans
Native speaker review of every language is a fixed step, not an optional one, since translation quality and tone are judgment calls a machine should not make unchecked. Deciding which markets get priority, and catching anything culturally off in a particular market even if the translation is technically correct, stays with your team and the reviewers in each market.
Guards
Every dubbed version is logged against the source script and the glossary used, so a reviewer can trace a translation choice back to its source. Nothing publishes without the native speaker review step signed off per language, and the glossary is a hard constraint, meaning brand terms cannot drift between languages even as the surrounding translation varies.
Before it runs unattended, we run a side-by-side dry run against a sample of your own AI video dubbing material so your team can see exactly what it would have done. Every build ships with a short written runbook so your team can pause it, adjust a threshold, or roll it back without waiting on us, and the running-cost estimate below is a starting budget you set, with an alert built in before it is crossed.

FAQ
How much does AI dubbing cost?
from $700 per video for up to 10 languages, live in 5 to 10 days depending on review turnaround from native speakers. Ongoing dubbing of a regular video output is quoted per batch.
Does the dubbed voice sound like the original speaker?
The voice generation is matched to the tone and pacing of the original speaker as closely as the target language allows; a native speaker reviews delivery, not just translation accuracy, before approval.
Who checks the translation is actually correct, not just fluent?
A native speaker reviews every language before it publishes, specifically for meaning and tone, not only grammar, since a fluent but wrong translation is worse than an obviously rough one.
Which languages can it dub into?
Up to 10 per pipeline run, chosen from your target markets; the common set is Spanish, Portuguese, French, German, Thai, Vietnamese, Indonesian, Arabic, Japanese and Korean, but we build around your actual markets.
What happens to brand terms and product names across languages?
A glossary of brand terms, product names and devices that should not be translated is set once and applied consistently across every language in the batch.
