Summary of Vocaloid and Voice Library Types (Including CeVIO and UTAU)

A Vocaloid producer who is also a music writerWakachan Araki
I started playing guitar in middle school and focused on band activities during my student years. I’ve been a hobbyist Vocaloid producer for over 15 years. After entering the workforce, I gained experience in various roles, including event sound engineering and videography/photography. As a writer, I’ve contributed introduction articles for music and manga websites, and in 2022 I had the opportunity to write the bonus liner notes for IA SUPER BEST. My specialties are Japanese rock, Vocaloid, and manga.

Starting with the 2007 debut of Hatsune Miku, the number of Vocaloid characters and voice libraries has grown alongside the expansion of the scene.

I’m sure each of you has your own favorite Vocaloid character.

In this article, we’ll give a quick overview of the many Vocaloid characters and the different types out there.

It’s recommended for anyone who wants to start making Vocaloid tracks but isn’t sure which voicebank to use!

Strictly speaking, “Vocaloid” refers only to certain libraries like Hatsune Miku and Kagamine Rin/Len, but here we’re using the term “Vocaloid” as a catch-all for other singing synthesis technologies and voice libraries as well.

Thanks for your understanding in advance!

Yume no Kesshou POPY・ROSE

r-906 – Strange Phone Call (ft. ROSE & POPY)

POPY and ROSE from the “Yumeno Kesshō” series, born from the mixed-media project BanG Dream!.

Released in 2022, POPY’s bright and energetic singing voice suits pop rock, while ROSE’s powerful and majestic vocals fit rock and metal tracks.

As heard in r-906’s “Kaidēnwa,” they also shine in stylish dance tunes.

Kotonoha Akane & Aoi

Odo Robo / Kotonoha Sisters with Zundamon

Kotonoha Akane and Aoi debuted as VOICEROID in 2014 and began showcasing their singing voices with a Synthesizer V version in 2017.

Akane speaks in Kansai dialect and Aoi in standard Japanese; the distinctive voices of these twin sisters have captivated many creators.

Their bright, clear timbre pairs exceptionally well with pop and electronic music.

In Umi-cha’s hit track “Odo Robo,” they deliver a nostalgic vocal performance.

Their pink and light blue, highly cohesive character designs are another big draw!
