About the Gumi voice
Gumi, also known as GUMI or Megpoid, is a green-haired Vocaloid character, a singing voice synthesizer persona voiced by Japanese voice actor Megumi Nakajima. Gumi is best known from the Vocaloid music scene, where producers have used the voice in a huge number of original songs shared online, and the character has also appeared in rhythm games. Megumi Nakajima is also known for her anime work and her own singing career.
The voice is clear, bright and youthful, with a lively, energetic delivery. It sits comfortably in a mid to upper singing range and tends to sound crisp and precise, with a pace that suits fast, rhythmic melodies as well as lighter pop lines. Expect a polished, slightly synthetic sparkle that works especially well for upbeat singing.
To get good results on voicechange.io, you can 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, use a clean, dry recording with no background noise or heavy reverb, and sing or speak in clear, steady phrases with distinct syllables. Fast, rhythmic material and bright, energetic delivery tend to suit Gumi best.

Tips for the best Gumi result
This model is centred around 240 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 Gumi 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.
