Kaai Yuki (歌愛ユキ) is a Japanese VOCALOID developed and distributed by AH-Software Co. Ltd., and was initially released in December 2009 for the VOCALOID2 engine. Yuki's vocals are based on an elementary school student. Since the voice provider was a young fourth grade girl at the time, her identity was never revealed for legal reasons. Her voice provider has spoken about Yuki for the character's 10th anniversary (2019)[2] and for VOCALOID's 20th anniversary (2024),[3] but still remains anonymous. She was the first female VOCALOID whose voice samples were not produced from an adult.
She was updated to the VOCALOID4 engine in October 2015, specially introducing another voice provider to supply growl voice samples due to her initial voice provider maturing.[4]
Concept
She and Hiyama Kiyoteru were released as "student" and "teacher" VOCALOIDs.
Etymology
The characters of her surname, "Kaai" (歌愛), mean "song" and "love" respectively. Her given name, "Yuki" (ユキ), comes from the kanji form (雪), meaning "snow". Together, her name means "love song of snow".
Appearance
Yuki is a 9-year-old elementary school student. She is said to be "as tall as 10 big apples" and "as heavy as 86 apples".
Yuki's red randoseru is a motif of YAMAHA's wind controller, WX5. Originally she was blonde in concept art.

History
Marketing
Yuki, along with SF-A2 miki and Hiyama Kiyoteru, were introduced to expand the VOCALOID market and give producers more vocal options to utilize.[5]
Until May 2011, all AH-Software VOCALOIDs were banned from KARENT.

- The Yuki vocal was designed to give a child-like vocal to producers. She represents a child's voice and was voiced by an actual child, making her a realistic representation of a child. The vocal is that of an amateur singer and does not give professional singing quality. However, due to the vocal source being of a child, the "natural" vocal has encountered updating issues over time.
