Vozo

Video dubbing & translation (SaaS) · Proprietary

Vozo is a commercial web app that runs a whole video-localisation pipeline in one pass: speech recognition, translation, text-to-speech with voice cloning, lip synchronisation and on-screen text replacement. It advertises 160+ target languages and regional accent variants. It is closed source and hosted only — the video is uploaded to their servers — with a free tier before subscription.

  • One pass from source video to dubbed video, no tool switching
  • Voice cloning with a choice of regional accent, not a generic AI voice
  • Re-translates text baked into the picture — slides, captions, overlays
