What Happens to Your Video
Five steps, fully automatic: the original music stays, the timing follows the original, and every speaker gets their own cloned voice.
Listen
Every spoken word is transcribed with precise timing.
Separate
Voices are lifted out so the music and sound effects stay exactly as they were.
Translate
A context-aware AI translates the whole conversation on our own servers, keeping meaning and tone.
Voice
Each speaker is re-voiced in the new language with a voice cloned from their own.
Mix
The new voices are timed to the original and mixed back with the original soundtrack. Subtitles included.
Tips for the Best Results
A few simple things help LinguaDub produce the most natural dub.
Upload the best quality you have
Clear audio gives the clearest voices. Upload the original file rather than a re-compressed copy.
Speech should be easy to hear
Music and sound effects are kept, but speech that is buried under very loud music is harder to understand.
Speakers who talk in turn
Each speaker gets their own voice. Conversations where people take turns come out best; heavy overlapping speech is harder.
Start with a short clip
Your first 3 minutes are free — try a short clip first to hear the result in your language.
Download within 72 hours
For your privacy, dubs are deleted automatically 72 hours after delivery, so save your copy.
Only upload what you may dub
Your own videos, family videos, licensed content, or Creative Commons content with attribution.
