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

A Vocaloid producer who is also a music writerWakachan Araki
I’ve worked in a variety of roles—regardless of pro or amateur settings—including live event PA, cameraman for video and photography, restaurant staff, and logistics center staff. I now spend my days as a part-time writer. I’ve contributed to music and manga websites with feature/review articles, and wrote the liner notes included as a bonus for 1st PLACE Inc.’s “IA SUPER BEST.” As for my music background, I started playing guitar in junior high and focused on band activities during my school years. For over 15 years since then, up to the present, I’ve continued releasing original tracks as a Vocaloid producer. My areas of expertise 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!

Summary of Vocaloid and Voice Library Types [Including CeVIO and UTAU] (11–20)

Star Realm

Let's go to an alien planet / Iyowa feat. Seikai (Take you to an alien / Iyowa feat. Seikai)

Hoshikai is a sound source produced based on the singing voice of virtual singer Isekai Jōcho.

In 2022, it drew attention as a release in the musical “isotope” series following Kafu.

Its tone is characterized by a slightly childlike quality with a breathy component, blending cuteness with a sense of fragility.

You can hear its capabilities in songs like “Let’s Go to Another Planet” by Iyowa and “Tokoshizume” by Inabakumori.

Hoshikai’s voice feels as if it carries an entire worldview on its own.

a cold; catching a cold

【Common Cold】The Night Before the Crime【Original】

Kazehiki is a voicebank for UATU created by Kurukuru Suuji-san.

As the name suggests, it was made using recordings done while they had a cold.

That gives it a distinctive—and appealing—husky quality.

Many listeners will likely be drawn to its noisy, raspy singing voice.

As you can see on the official page, there are several different library variants under the same “Kazehiki” name—some gentler, some more delicate.

It’s hard to choose which Kazehiki to have sing, isn’t it?

Zundamon

Zunda Dancing / Namigure feat. Zundamon

Zundamon was born as a derivative of Tohoku Zunko, a character based on zunda mochi.

After serving for a long time as a mascot-like character, it suddenly became humanized in 2021 and was turned into a voice library, which drew a lot of attention.

It can be used as a UTAU and NEUTRINO voicebank, known for its cute singing voice.

In a curious phenomenon, many songs have been created using Zundamon itself as a motif—like Namigure’s “Zunda Dancing” introduced here—and have gained popularity.

Saying it like that kind of brings back memories of the early days of the Vocaloid boom, doesn’t it?

Yamine Renri

Nerve Impulse – Police Piccadilly feat. Yamine Renri / Police Piccadilly

Yuzuri serves as the CV for the UTAU voicebank Yamine Renri.

Judging by the official illustration and the character’s appearance, you might expect a cute voice, but in reality it gives quite a mature impression.

Of course it fits cute songs, but it also handles cool, elegant tracks with ease.

Take Police Piccadilly’s “Nerve Impulse,” for example—one listen and you’re instantly captivated.

It’s a voicebank that really expands your imagination—and your creativity—about how to have it sing.

ONE

Please, Darling / ONE – Nanahoshi Orchestra

ONE is a voice library produced by 1st PLACE, which also manages musicians.

Announced in 2015 as the little sister of the voice library IA, it features a lively vocal quality that is appealing and versatile enough to fit any music genre thanks to its lack of idiosyncrasies.

With parameter adjustments, it can even produce a quite mature voice.

Incidentally, the illustration was drawn by Aka Akasaka, known as the author of the manga “Kaguya-sama: Love Is War.”

VY1

Luna – Perfect Peace (Perfect Piece) feat. VY1

When you think of Vocaloid, you might picture characters with defined appearances like Hatsune Miku or Kagamine Rin, but VY1, which debuted in 2010, doesn’t have that.

That was Yamaha’s intention: it was created under the concept of “usable as a single instrument” and “leaving the character aspect to the user.” In Luna’s “Perfect Peace,” it delivers a fresh yet solid singing voice, while in EZFG’s “Cyber Thunder Cider,” it takes on a cutting-edge tone.

It’s a remarkably versatile voice library that sings exactly as the user envisions.
