AI dubbing: your video in another language, with the mouth to match

• Transcript

  What happens

  Every word and when it is said

  Why it matters

  You can't translate to length without knowing the length

• Translation

  What happens

  Written to fit the time, not word for word

  Why it matters

  A literal line runs long and falls out of sync

• New voice

  What happens

  The lines read in the new language

  Why it matters

  Matched to the original's pace and tone

• Lip sync

  What happens

  The mouth moved to the new words

  Why it matters

  Without it, it's a voiceover, not a dub

Lip sync is the one step you can skip. If the speaker is mostly off screen, or the shots are wide, a voiceover in the new language is cheaper and nobody will notice. When a face fills the frame, matching the mouth is what makes it believable.

• One speaker facing the camera: interviews, founder videos, explainers.
• Clear speech without music underneath it.
• Lines of normal length, with pauses between them.
• Harder: several people talking over each other, shouting, singing, or a face turned away.

Start where your viewers already are. Your analytics show which countries watch your videos or visit your store; dub into the top one or two languages there before anything else. For most English-language brands that means Spanish, Portuguese for Brazil, French and German.

• Dub the videos that already work in your own language first: your best ad, your best explainer.
• Keep one version per language, and name the files clearly so they're easy to swap.
• Translate the on-screen text and captions too, not only the speech.
• Check local rules for ads, such as what counts as a health claim, before you run them.

1. 01
   Have a native speaker read the scriptBefore the voice is made, have someone who speaks the language read the translation. It's the cheapest moment to fix a mistake.
2. 02
   Watch the close-upsWatch every shot where the face fills the frame, with the sound on, and look for words that land late.
3. 03
   Check names and numbersPrices, dates, product names and phone numbers are the things a translation gets wrong most.

Only dub people who have agreed to it: yourself, your team, or someone who said yes in writing. Making a real person appear to say something they didn't say is not allowed, in any language. Tell viewers the voice was made with AI, too. In more and more places, the law asks for it.
