AI Video Dubbing
Without the Studio

Capto’s AI dubbing feature replaces the original audio in your video with a natural-sounding text-to-speech voice in any language you’ve translated into. Powered by OpenAI TTS, the dubbed audio is generated segment by segment, timed precisely to match the original subtitle timestamps so speech stays in sync with on-screen action. You can download the dubbed audio track alone, or request a fully dubbed and burned-in MP4 with both the translated subtitles and the new voice track mixed together — no re-recording, no studio time, no post-production. Pay per minute of video duration, using the same credit system as the rest of Capto. Dubbed exports are ready in minutes.
