Best AI video translators for dubbing and subtitles
Updated · Prices change often; confirm on each tool's site.
For most creators, HeyGen is the easiest AI video translator: upload a video and get it back in another language with a cloned voice and lip-sync, and its Creator plan lists 175+ languages. Pick ElevenLabs if natural-sounding dubbed audio matters most (Dubbing Studio starts on the $6/month Starter plan), and Synthesia for business or training videos, since its free plan includes 10 minutes of video or dubbing a month.
AI video translators transcribe your video, translate the script and re-voice it in another language, often in a clone of the original speaker's voice, with optional lip-sync and subtitles.

Our top 3 picks

ElevenLabs

Synthesia

How to do it
- Start from clean audio: one speaker at a time and quiet background music give the best translated voice.
- Upload the video to HeyGen, ElevenLabs or Synthesia and choose the target languages.
- Read the translated transcript before you export and fix names, product terms and numbers.
- Use lip-sync only for shots where someone talks on camera; for voice-overs and screen recordings, dubbed audio alone is enough and usually costs fewer credits.
- Export subtitles as well, and have a native speaker check anything customers will see.
FAQ
Can AI translate a video into another language in my own voice?
Yes. HeyGen, ElevenLabs and Synthesia can all re-voice a video in another language using a clone of the original speaker's voice. Only clone voices you own or have permission to use.
Is there a free AI video translator?
Each has a free plan with limits: HeyGen allows 3 videos a month up to 1 minute (with a limited lip-sync translation trial), Synthesia includes 10 minutes of video or dubbing a month with a watermark, and ElevenLabs includes 5 minutes of automatic dubbing with a watermark and no commercial license.
Should I dub my video or just add subtitles?
Subtitles are cheaper and keep your real voice. Dubbing reaches people who won't read along, especially on phones and TVs. Many creators start with subtitles, then dub their best-performing videos.
Which is best for training videos?
Synthesia, because it is built for business video, keeps the speaker's voice and accent when dubbing, and its free plan gives you 10 minutes a month to test. See our Synthesia vs HeyGen comparison for the details.
