AI dubbing lets you publish the same video in several languages without re-recording it. The tool transcribes your speech, translates it, regenerates it in your own cloned voice and, with the best tools, adjusts your lip movements to match.
Results vary a lot with the source video: a clear single speaker facing the camera gives the most convincing result. This guide shows which tool to use for presenter videos, for voice-only dubbing and for social clips.

| Synthesia | Best for training videos in many languages | From $29/mo |
| Captions | Best for social clips on mobile | Free plan, paid from $13/mo (annual) |
