AI dubbing: the same voice in 31 languages
Dubbing a video into another language takes four steps: a transcript, a translation, a voice for the translated lines and an edit that fits them to the picture. SuperClonica does the voice step: every voice in the catalog, and every voice you train, speaks all 31 languages of Supertonic 3 with the same timbre.
This guide explains honestly which parts of dubbing SuperClonica covers and which it does not, how to fit translated lines to the timing, and how to voice a whole video in another language on your own computer.
What AI dubbing involves
Chinese is not among the 31 languages yet.
- Transcript and translation: done by you, a translator or a translation tool. SuperClonica does not translate.
- Voice: SuperClonica reads each translated line in the same voice, in any of 31 languages.
- Timing: you place the lines in a video editor.
- Lip sync: not offered; it suits voice-over, narration and off-screen speech best.
Test a translated line free online
On the page of any voice, paste a translated line of 30 to 100 characters, choose the target language and press Voice it. In a few seconds you hear how the voice sounds in that language and can download the recording. No account is needed.
Fit the lines to the video
Every voice keeps the accent of the recording it was made from, so listen to a few lines in the target language before you commit.
- Work line by line from the subtitles or the script, one audio file per line.
- Translations often run longer than the original; shorten the text rather than speeding up the voice.
- For a tight line, a slightly higher speed helps: the default is 1.05, try 1.1.
- Write numbers, names and units the way they should be read in the target language.
A whole video offline
Install the free SuperClonica engine: python -m pip install superclonica-cpu. Voice each translated line with one command, changing only the text and the language: superclonica --text "Willkommen zurück auf dem Kanal." --voice my-voice.json --lang de --output line-001.wav. A small script can loop over all subtitle lines and number the files. The engine runs offline on an ordinary processor, with no character limit, so a whole video in five languages costs nothing extra.
Your own voice in other languages
The most natural dub keeps your own voice. Record a clean phrase of 5 to 10 seconds of yourself, create a voice in the studio and train it on a computer with an NVIDIA graphics card; training on your own hardware is free. The trained voice then speaks all 31 languages, with a trace of your own accent. Dub other people’s voices only with their consent. Without a suitable card, order the voice on the exchange from an author who trains it.
