**Hiyama Kiyoteru** (氷山キヨテル) is an upcoming Japanese vocal to be developed and distributed by AH-Software Co. Ltd. and is expected to release as an AI voice database for *Synthesizer V Studio* in December 2024. He was initially released as one of AH-Software's three debut voicebanks for the *VOCALOID2* engine (along with miki and Kaai Yuki) in December 2009; he was updated to *VOCALOID4* in October 2015 and received two voicebanks.

He is voiced by Japanese singer Kiyoshi Hiyama.

## Concept

Hiyama Kiyoteru and Kaai Yuki were conceived as a "teacher" & "student" pair when initially released for VOCALOID.

### Etymology

His surname "Hiyama" seems to be taken from his provider's name ("Kiyoshi Hiyama"). His Ice Mountain name of "Ice Teru" is a play on words; "Hiyama" (氷山) means "ice mountain."

### Official profile

Kiyoteru is a teacher who participates in a rock band called "*ICE MOUNTAIN*" on weekends, with the stage name "Ice Mountain Teru." According to the book, the default configuration for his VOCALOID2 software package happens to be Kiyoteru's vocals as a rookie singer. He is also said to be good at mathematics. The book also reveals that he was raised by Kiyoshi, a catholic priest who adopted him.

His favorite microphones were listed:

* BEHRINGER Ultravoice XM8500 (during his junior high and high school years)
* SHURE SM58 (college years)
* SHURE Beta 58A / RODE NT1-A (current favorite)

Although he's described as a good-natured, a bit shy and friendly individual, he assumes a more daring and cool personality when he removes his glasses. This was suggested on some of the early promotional arts, and later confirmed within the book.

### Relations

* Kaai Yuki - Student.
* ICE MOUNTAIN - Band.
* Kiyoshi - Foster father.
* Minase Kou - Fellow teacher.

## History

Planning of the first three AH-Software Co. Ltd. singing vocals began in 2007. **Hiyama Kiyoteru**'s voice was provided by a Japanese singer, whose name was back then a secret. His VOCALOID2 voicebank, as well as those of SF-A2 miki and Kaai Yuki, were released on December 4, 2009. On August 12, 2010, Kiyoshi Hiyama himself announced on Nico Nico Live that he was Kiyoteru's voice provider.

Kiyoteru and many other AH-Software vocals were announced to be receiving updates for VOCALOID4 on November 20, 2014's livestream, after their silhouettes were revealed on a poster two weeks earlier without providing any further context. On May 28, 2015, AHS showed a new design for him to promote the AniNite concert in Vienna, Austria; its relation to his V4 update was unknown at the time. On August 17, it was noted that Kiyoteru and Yuki would receive demos some time after the AniNite concert ended, and that Kiyoteru's V4 voicebank was recorded from scratch to improve his upper and lower ranges. On September 30, Kiyoteru was confirmed to receive a Natural and Rock vocal, also gained a new design corresponding with the Rock voicebank, and adopted the AniNite concert design shown off in May as his Natural voicebank key artwork; both vocals, which could be purchased separately or together (a Starter Pack option bundling both with the VOCALOID4 Editor was also offered) were released on October 29, 2015.

### 2023

On December 1, 2023's AHS livestream, it was announced that both miki and Kiyoteru would be receiving AI voice databases for Synthesizer V Studio for their joint 15th anniversary in 2024. With regards to Yuki, it was noted that it would be very difficult to record a new voice library for her (due to the fact that her original voice provider, who back then in 2009 was a child and as of today still remains unrevealed for legal reasons, is now an adult and her voice quality has changed), and as for using her existing V4 Natural voicebank to derive a new voice database (whether a new Standard voice database from its raw samples or a Synthesizer V Plus-style AI voice database trained from songs performed by it was not mentioned, though), they would still have to first consult with Yamaha Corporation before carrying it out.

## Voice Database Information

### Voice Databases

Product Information
**Versions**

  **Lite Version/FLT Available?:** TBA  **Starter Pack Available?:** TBA  **Web Version Available?:** No
**Package details** as noted:

Hiyama Kiyoteru is expected to be a masculine Japanese voice database based on the singing style of Kiyoshi Hiyama. As expected of an AI voice database, Kiyoteru will be capable of singing with a more human-like and realistic voice.
**Vocal traits** as noted:

With Diffusion Probabilistic Models (DPM), Kiyoteru will be able to sing more realistically through changes in volume and breath, further enriching singing details, making each singing unique, and providing creators with more options. Through this mode, he will be able to use AI Retakes to create multiple "takes" of a sung section to find an ideal vocal without the need for "laborious tuning". This feature is only available in the Synthesizer V Studio Pro Editor.
**Phonetic notes** as noted:

* Phoneme format: Romaji
* Through Cross-lingual Singing Synthesis, Kiyoteru is expected to sing in not only Japanese but also in English, Mandarin Chinese, Cantonese Chinese, and Spanish. This feature is only available in the Synthesizer V Studio Pro Editor.

## Voice Libraries

* Hiyama Kiyoteru (*VOCALOID2*), December 4, 2009
* Hiyama Kiyoteru V4: Natural & Rock (*VOCALOID4*), October 29, 2015
* Hiyama Kiyoteru AI (*Synthesizer V Studio*); In development, expected for December 2024

## Additional Information

### Marketing

Kiyoteru, along with miki and Kaai Yuki, was introduced to expand the selection of VOCALOIDs, giving producers more choices.
