Dublio: Dub Video with AI

Dublio is an AI video translator and video player for the videos on your phone. It listens to the speech, writes it down as subtitles, translates them and dubs them in your language with natural AI voices. Dub video files, make AI subtitles or translate a subtitle file, all on your device.

Your videos are not uploaded and no account is needed. Once the models are downloaded, the AI dubbing and translation run on your phone without an internet connection.

▸ AI dubbing with voice clone
Pick a video and the language you want to hear. Dublio recognizes who is speaking and gives each speaker a different voice. With voice clone, each speaker is dubbed in their own voice; Dublio clones only the voices of the people in that video. The original speech is turned down under the dub, while music and sound effects stay as they were. Dub video lectures, interviews, series or holiday clips the same way.

▸ AI subtitles and caption generator
Prefer to read? Use Dublio as a caption generator: it makes subtitles for videos in the original language or translated into yours. Show the translation and the original together as dual subtitles, a handy way to learn a language while you watch.

▸ SRT translator and subtitle translator
Already have an SRT file? The SRT translator turns it into your language, or into a dub with voices. As a subtitle translator it keeps every line on its original timing.

▸ Start watching before it finishes
Playback starts as soon as the first part is ready, and the rest follows in the background. Line up several videos and they are translated one after another.

▸ A subtitle player made for dubs
Watch in Dublio's own video and subtitle player: set the subtitle size, color, background, shadow and position, change the playback speed, follow the transcript and jump to any line, keep watching in picture-in-picture, and skip with full-screen gestures. Dual subtitles and the video's own subtitles can be switched on or off.

▸ Export and share
Save the dubbed video as an MP4, with the subtitles drawn onto the picture or added as a separate track, or save the subtitles as an SRT file. Share the result straight from the app.

▸ Movie translator in many languages
The app is available in 12 languages, and it can translate, subtitle and dub videos in dozens of languages. Use it as a movie translator for a foreign film, or as a video translator for a course. Make subtitles for videos in a language even when it can't be dubbed on your device.

▸ Free and Pro
The free version lets you dub or subtitle a few shorter videos each month, shows short ads and needs an internet connection to start a video. Dublio Pro removes the monthly limit, handles longer videos and removes the ads. Monthly and yearly plans are available.
Pro is an auto-renewing subscription: it renews unless you cancel at least 24 hours before the end of the current period. You can cancel anytime under subscriptions in the Play Store.

▸ Good to know
Dubs and translations are made by AI and can contain mistakes. Exported files state that their dub is AI-generated. Only use videos you have the right to dub, and never use a cloned voice to mislead others.
