Review & voice

Tweak the translation, pick a voice for each speaker β€” or clone the real one β€” and preview any line.

4

Download

Get a synced voiceover plus clean, soft-subtitle, and burned-in versions, and the subtitle file.

Everything you need to localize at scale

πŸ—£οΈ

A voice per speaker

Automatic speaker separation gives each person their own natural AI voice β€” interviews sound right.

🧬

Voice cloning

Clone the original speaker from a short sample so the translation sounds like them.
