Kaai Yuki

Kaai Yuki (歌愛ユキ) is a Japanese Vocaloid released in December 4, 2009. She is developed by AH-Software. The characters of her name, "歌愛", mean "song" and "love" respectively.

History
Her voice is taken from recordings of an actual elementary school student. However, the name of the one who offered the voice for Yuki is still unknown.

She has three demos released, "±", "Vocaloid Grade School Student", and "Try again".

Vocaloid 3; starter pack
AH-Software is releasing their Vocaloid 2 era Vocaloids with Vocaloid 3 starter packs. However, there have been no updates for the 4 voicebanks and although they are sold with Vocaloid 3 they are all still Vocaloid 2 voicebanks.

Marketing
She is meant to be portrayed as an elementary school student, officially she is a student of Hiyama Kiyoteru and what is in her red randoseru is a motif of Yamaha's wind controller, WX5.

Usage for Music
Yuki and Hiyoteru were designed to be Voclaoids that had human-esque traits about them. Yuki is designed to sing childrens songs and has an innocent, soft and cute voice. Her child-like voice makes her unique amongst the vocaloids and allows for a soft, sweet style of song. Because of this, Yuki can not sing like a professional singer as she is intended to sound like an amateur, different from Crypton's "project if...". Since she has a breathy voice and strong consonant sounds, her Japanese sounds very natural. However, some users say the beginning consonant sounds get shorter as well as other AH-S vocaloids.

Yuki's software may occasionally have an installation error when installed, this is related to her engine version and may show up when installing her over a more updated Vocaloid 2 like Gachapoid or Lily. Help can be found within the fandom on fixing this. This can be fixed very easily, however, if a newer Vocaloid installed after her installation, otherwise re-installation in release order is another solution.

Until late May 2011, works made using the AH-Software Vocaloids were banned from being published through Karen-T because premission had not been granted for their use with the website by AH-Software.

Vocaloid 2 is unsupported as of 2011 by Yamaha. These voicebanks however can be imported into Vocaloid3.

Reception
Yuki's design received complaints within the western fandom and the Japanese fandom. Since she was intended to be the counterpart to Kiyoteru Hiyama, the biggest concern was that the pair would become the subject of pedophilic based artwork/songs because of the Lolicon culture. It also received complaints of looking too plain and ordinary compared to previous past Vocaloids.

As well as her design being the subject of criticism, her voice was the subject of complaints since it was too soft, although this was mostly linked with the problem of her portrayal becoming the subject of pedophilic imagery. It has since been pointed out that children tend to sing with a soft voice and since school children were used as the subject of the recordings, it was only natural for her voice to sound the way it did. Most of these complaints have since ceased.

The three Ah Software Vocaloids were slow to gain popularity and for a while were amongst the least popular Vocaloids. Kaai Yuki was the second noted in 2010 as the second most popular of the trio.

She is also praised by Western "Japanese to English" users as having one of the easiest pronounications to mimick English with, however, like all Japanese Vocaloids she is still limited.
