300ms Latency
Your shout reaches the squad fast enough for live build fights and rotations.
Asta is the loudest hero in anime: a boy born with zero magic who answers every setback by yelling louder and swinging a bigger sword. The Asta Voice Changer from Dubbing AI puts that raspy, never-give-up shout on your mic, so your Fortnite squad hears a Black Clover-style battle cry in real time. It is a free voice changer for PC with 300ms latency and works in party chat, Discord and OBS.
✓ Free voice changer • ✓ 500+ AI voices • ✓ Under 300ms latency

Asta is the main character of Black Clover, the manga by Yūki Tabata that ran in Weekly Shōnen Jump and became a long-running anime. He is an orphan in a world where everyone has magic except him.
Instead of spells, Asta fights with anti-magic swords from a five-leaf grimoire. His whole personality is effort: he trains harder, shouts louder and refuses to quit, which is why fans connect his voice with pure determination.
For a crossover like Fortnite × Black Clover, that loud and hopeful energy is what players want to copy. An anime voice changer lets you borrow it without straining your own throat.
The crossover gives you the look. The Asta Voice Changer gives you the voice that matches it.
The Asta Voice Changer is an AI voice preset inside Dubbing AI that turns your voice into a loud, raspy, anime-hero shout in real time. It runs as a virtual microphone, so any app that accepts a mic input can use it. You can browse more presets on the Dubbing AI voice changer page.
Fortnite crossovers are about playing as someone else. Matching your voice to an anime skin makes squad chat more fun and gives streamers an instant bit. Because the voice changer app works at the audio level, it does not touch Fortnite's files, and the 300ms latency keeps callouts in sync with the fight.
In our testing, the preset works best when you speak with energy: short, punchy lines like "Push now!" come out closest to Asta. Quiet mumbling loses the effect. Add a battle-cry clip from the Dubbing AI soundboard for big moments, or grab fan-made clips from community sounds.
Asta talks at full volume. The preset adds forward energy so even normal callouts sound like a battle cry.
A slightly hoarse, strained texture is what makes his shout recognizable. The AI voice changer reproduces that grit.
