About the Giyuu Tomioka voice
Giyuu Tomioka is a character from the anime and manga series Demon Slayer: Kimetsu no Yaiba. He is the Water Hashira, one of the elite swordsmen of the Demon Slayer Corps, and is known for his calm, reserved manner and his mastery of Water Breathing. Giyuu appears across the TV series, the films and related games, and has become one of the franchise's most recognizable characters.
In Japanese, the voice is calm, low and steady. Giyuu speaks in a measured, even tone with little outward emotion, and his pace is unhurried, with short, clipped lines and deliberate pauses. The delivery feels quiet and composed rather than loud or dramatic, and any warmth or intensity comes through subtly. Expect a cool, controlled, stoic sound.
To get good results on voicechange.io, you can record or upload speech, type text to hear it spoken in this voice, or make a song cover. The pitch is matched to the voice automatically, so you don't need to adjust it yourself. For this voice, speak in a flat, relaxed, understated way and keep your pace slow and even. Avoid shouting or exaggerated emotion, since the character's restraint is what makes it recognizable. A clean recording with little background noise also helps.

Tips for the best Giyuu Tomioka result
This model is centred around 120 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) isn't shifted, since it already fits, and a typical higher voice (around 210 Hz) is shifted about 10 semitones down. Gaps under 4 semitones are left alone, and shifts stop at one octave. If the result sounds strained, nudge the slider one or two steps back toward your own voice; for song covers, keep it at 0, +12 or −12 so the vocal stays in key. How pitch works.
- Record in a quiet room with no music in the background; noise is the main cause of robotic-sounding results.
- Perform the line the way Giyuu Tomioka would say it. The model copies your timing and emotion, only the voice changes.
- For song covers, pick a track with one clear lead vocal and little reverb.
