Introduction

Studio VOXYZ was founded in 2009 as Project UTAU XYZ by MystSaphyr, the voicer of the UTAU Kikyuune Aiko.

It is a multimedia project that aims to promote the use of character-based singing synthesizers. The project name acts as both a voicebank series and a personal music label for Myst.

This site hosts downloads, media and information for all the voicebanks and characters in the VOXYZ series and related projects. This includes information about convention panels and streams held by Myst.


What are “singing synthesizers”?

Singing synthesis is exactly what it sounds like: software intended to replicate the human singing voice. This website deals with all manner of vocalsynth software, but it primarily tends to focus on UTAU, VOCALOID, DeepVocal and CeVIO.


What is VOCALOID?

  • VOCALOID is commercial singing synthesis software created by Yamaha.
  • Third party companies produce “voicebanks” for the software engine, which can be individually purchased.
  • To use VOCALOID, you add notes in a piano roll interface, and type in lyrics.
  • You can edit (tune) parameters such as pitch, vibrato and dynamics to make the voice more expressive.
  • The most popular VOCALOID is Hatsune Miku (初音ミク)
  • Miku’s popularity is why most VOCALOIDs after her have character avatars associated with each voice as an effective marketing technique.
  • As of 2019, there are over 70 voices available for the VOCALOID software, and the software is currently on its 5th iteration.

What is UTAU?

  • UTAU is freeware Japanese singing synthesis software.
  • UTAU “voicebanks” (“ongen/音源” in Japanese) are folders that contain prerecorded voice samples.
  • The UTAU software also uses a piano roll interface.
  • However, due to its programming limitations, UTAU input is purely phonetic, unlike VOCALOID which can have inbuilt dictionaries for various languages.
  • The term UTAU (or “UTAUloid”) can refer to an individual voicebank, which will likely be represented by a character avatar thanks to the influence of VOCALOID.
