Dubly AI

Dubly AI is an AI video translation tool that keeps your content sounding and feeling native in the target language. Upload a video, pick your target language(s), and get a translated version with the original speaker’s voice cloned—so the voice is not replaced by a generic actor.

Beyond audio, Dubly AI focuses on the moments where dubbing often looks “synthetic.” Its Lip Sync 2.0 model is designed for challenging shots such as occluded faces, dynamic movements, multispeaker scenarios, side angles, and close-ups, while preserving video quality up to 4K. Lip-synced subtitles are also included and timed to the new audio track.

For teams, Dubly AI supports brand consistency with a configurable glossary for product names and technical terms. It’s hosted in Germany for maximum data sovereignty, with no training on customer content and GDPR-aligned security measures. If you’re localizing at scale, the Dubly AI API can automate translations via endpoints like /v1/translations.

Does Dubly AI dub using the original speaker’s voice?

Yes—Dubly AI uses voice cloning so the translated audio sounds like the original speaker from the source video.

Will the lip movement match the translated language?

With lip sync enabled, Dubly AI generates mouth movement matched to the new language track to keep the result natural, including for harder shots like occluded faces and dynamic close-ups.

Can I keep my brand terminology consistent across languages?

Yes—store your product names and key technical terms in a custom glossary so terminology stays consistent in translations.

What languages are supported?

Dubly AI supports 100+ source languages and 40+ target languages for video translation and lip-synced dubbing.

How does Dubly AI handle data security?

Dubly AI is hosted in Germany and provides options like a DPA on request. It also states no AI training on your content, with additional GDPR-compliant security controls.

Is there an API for translating many videos automatically?

Yes—the Dubly AI API supports automating the translation workflow using endpoints such as /v1/translations with options like lip sync and voice cloning.
