You can now edit the speaker attribution, create new speakers, and rename then in your dubbed videos. Available for creators on Enterprise plans.

How it works and why it matters
Dubbing relies on automatically detecting who's speaking. That detection doesn't always get it right—a line can end up attributed to the wrong person, or a distinct voice can go undetected entirely. Until now, fixing that meant either living with an unusable dub, or correcting it word-by-word and still ending up with awkward pauses in the result.
Now you can fix it directly:
- Reassign a speaker on any segment with one click, when a line's been attributed to the wrong person
- Create a new speaker if someone's voice wasn't picked up as distinct—this builds a unique voice clone from the audio you assign to them
- Rename speakers with real names instead of "Speaker 1, 2, 3," so your team can review edits without guessing who's who
