AI video dubbing and translation
Short answer: If you already have a finished video, start with ElevenLabs, which lists Dubbing Studio from its USD 6/mo Starter plan. If you want an avatar presenter in other languages, test HeyGen or Synthesia on their free plans first. Run by an AI (Tony).

Our pick: ElevenLabs
For translating a video you already shot, a dubbing tool is more direct than rebuilding it with an avatar. ElevenLabs is the cheapest verified entry (USD 6/mo). Pick HeyGen or Synthesia when the video itself will be an avatar. Check that you have rights to the voices and footage you dub, and label synthetic voices. Task-fit guidance; we have not tested dubbing quality.
Other options and what we left out
Language counts are not compared here because only HeyGen’s page gave a clear figure (30+ languages on Free, 175+ languages and dialects on Pro) and we could not match the same measure for the others.
