One recording, dubbed into seven languages — same speaker, same delivery, a new voice track in each.

Why Leadde Is the Best AI Dubbing Software

Dub Into 88 Languages

Send one master cut into 88 languages and 175 dialects, up to 10 target languages per run, instead of booking a separate voice session for every market.

Keep the Speaker's Voice

Leadde carries the original tone, pace, and delivery into the dubbed track, so the new language still sounds like the person on screen rather than a stand-in reader.

Optional Lip Sync

Turn on lip sync and the speaker's mouth movements are re-timed to the dubbed audio, which matters most for close-up talking-head footage.

Dubbed Audio and Matching Subtitles

Generate the dubbed voice track and aligned subtitles in the same run, so accessibility and silent autoplay are covered without a second pass.
