Sukuna AI voice: make Sukuna say anything

Ryomen Sukuna, the King of Curses from Jujutsu Kaisen, never needs to shout: he is calm, contemptuous and sure he is the strongest in the room. That calm menace is exactly what fans want in edits, fan scenes and memes.

The SuperClonica catalog has a fan-made Sukuna voice for Supertonic 3. This guide shows what it sounds like, how to write lines with real menace and how to voice whole scenes offline.

What the Sukuna voice sounds like

A low, calm man’s voice that suits Sukuna’s cold, unhurried menace. It was recorded in English, so it sounds most natural in English and keeps an English accent in other languages. It is a fan-made voice, not the voice of Junichi Suwabe, Ray Chase or any other voice actor, and it is not endorsed by the creators of Jujutsu Kaisen.

Make Sukuna say a line free

On the voice page, type a line of 30 to 100 characters, choose the language and press Voice it. In a few seconds you can listen and download the recording for your edit, with no account.

Make Sukuna sound menacing

His menace comes from calm. Write short, certain sentences, use full stops instead of exclamation marks and start a new sentence where he would pause. A slower speed, such as --speed 0.9 in the engine, makes him even more unhurried. Voice Yuji, Megumi or a narrator with other voices and cut the dialogue together. Write your own lines rather than quoting the series word for word.

Whole scenes offline

For a fan scene or a long edit, buy the voice once, download its file and install the free SuperClonica engine: python -m pip install superclonica-cpu. Save the lines in a text file and voice them with one command: superclonica --text-file sukuna.txt --voice sukuna.json --lang en --output sukuna.wav. The engine splits long texts at natural pauses and runs offline on an ordinary processor, with no character limit.

Fan fun, not deception

Use the voice for fan scenes, edits, memes and personal projects within the SuperClonica terms. Do not present the audio as an official clip or as a real actor’s words.
