AI video dubbing

Let your video speak their language.

Subtitles ask people to read. Dubbing lets them listen. SubFlow transcribes the speech, translates it, and speaks it back in an AI voice timed to the original — in about 85 languages.

Dubbing is available in the SubFlow apps for Android and HarmonyOS. On the web you can create, edit and export subtitles.

01

About 85 languages

Two voice providers between them cover roughly 97% of the target languages people actually pick here, Persian and Arabic included.

02

Timed to the original

Each line is fitted to the gap it has to fill, so the dub tracks the picture instead of drifting further out with every sentence.

03

Fix the words first

The dub is spoken from the translated subtitles, so correcting a name or a term in the editor changes what the voice says.

Workflow

From video to finished subtitles in three steps.

1

Upload and transcribe

Add the video or audio. SubFlow writes the speech out as timed captions in the original language.

2

Translate and choose a voice

Pick the target language, review the translation line by line, then choose from the voices available for it.

3

Export the dub

Take the dubbed audio track on its own, or the finished video with the new voice in place.

Common questions

Everything you need to get started.

Which languages can I dub into?

About 85, including Persian, Arabic, Spanish, Portuguese, Indonesian, Turkish, Hindi, Japanese, Korean and Chinese. The voice list for your chosen language is shown before you generate anything.

Does the dub stay in sync with the video?

Each line is fitted to the window it has, using the gap before the next line where one exists, so timing does not drift across a long video.

Can I change the wording after hearing it?

Yes. The dub is generated from the translated captions, so edit the line and regenerate that segment.

Do I keep the original audio?

Your source file is untouched. Export the dubbed track separately, or a video with the new voice, whichever you need.

Is dubbing included in the free plan?

No. Dubbing is part of the Pro plan; subtitles and translation are available on every plan, including the free one.

Is it the same as a text-to-speech reader?

The voices are neural text to speech, but the value is the rest of the chain: recognising the speech, translating it in context, and timing each line to the picture.
