About the Kasane Teto voice
Kasane Teto is a fictional singing character with red drill-shaped twin tails, best known in the UTAU and Synthesizer V communities. She began as a fan-made UTAU voicebank and grew into a popular character in online music culture. Fans have given her a large body of original songs, covers, illustrations and videos. She is also widely associated with a love of French bread, which shows up often in fan art and memes.
Teto's voice is bright, clear and youthful, with a bold, lively edge that suits energetic pop and rock. Her delivery is crisp and direct, and she sounds most at home in upbeat, melodic singing. Expect a synthetic, character-driven tone, not a natural everyday speaking voice.
To get good results on voicechange.io, record or upload speech, type text to hear it spoken, 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, clean and expressive input works best. Use a clear recording with little background noise, and sing or speak with distinct syllables and steady rhythm. For covers, a dry vocal with minimal reverb gives the cleanest conversion. Try upbeat, melodic material first.

Tips for the best Kasane Teto result
This model is centred around 260 Hz. With auto pitch on, a typical deeper voice (around 120 Hz) is shifted a full octave up (the maximum), and a typical higher voice (around 210 Hz) isn't shifted, since it already fits. 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 Kasane Teto 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.
