Quick answer: AI dubbing lets you take one explainer video and release it in ten languages for a fraction of what studio voice work used to cost, often 70 to 90 percent less. Animated videos are the easiest to localise because there is no mouth to sync. The catch: you still need a native speaker to check each version, the on-screen text has to be swapped too, and you need written consent before cloning anyone’s voice.
Why is everyone talking about AI dubbing?
Because it got good and got cheap at the same time. The AI dubbing market is growing at about 44 percent a year and is expected to go from roughly $32 million in 2024 to almost $400 million by 2032 (source). For a SaaS company selling in Europe, LATAM or Asia, that means the German, Spanish and Japanese versions of your homepage video are no longer a $10,000 line item.
Why is animation easier to dub than live action?
Live action has a person’s mouth on screen. If the new language does not match the lip movements, it looks wrong. Animated explainers rarely show lips, so the new voice just needs to fit the timing of each scene. That is a small edit, not a re-shoot. It is one more reason SaaS companies with global customers choose 2D animation.
What has to change besides the voice?
- On-screen text. Labels, buttons and headlines need translating and re-fitting. German is about 30 percent longer than English.
- Numbers and formats. Currency, dates, decimal commas.
- Timing. Some languages run longer, so scenes may need an extra second.
- Captions. A new caption file per language.
- Cultural details. A hand gesture or an example company name that does not travel.
What is the right process?
- Lock the English master and get the source files from your studio.
- Translate the script with a human, then generate the AI voice per language.
- Swap on-screen text in the layered project.
- Re-time scenes that run long.
- Have a native speaker watch each version once. This step catches the errors that make you look careless.
- Export, caption, and publish each version on its own page for SEO.
What are the rules on voice cloning?
If you clone your founder’s voice so the German version sounds like him, get it in writing first and keep the consent with the project files. Never clone a voice actor without a contract that covers it. If in doubt, use a stock AI voice per language.
How much does it cost?
Per language, AI dubbing plus text swaps and a native review usually lands between $150 and $500 for a 60-second explainer, compared with $1,500 to $3,000 for a studio voice actor and re-edit. Ten languages for the price of one. The English master is still the expensive part, which is why it is worth making it well. See explainer video cost.
Quick questions
Is AI voice quality good enough for a homepage?
For most languages, yes in 2026. Test two voices and pick the calmer one.
Should each language get its own YouTube video?
Yes. Separate videos with titles in that language rank and get cited in that language.
Can you localise a video you did not make?
Only if you have the layered source files. If not, on-screen text cannot be changed cleanly.
