Hatsune Miku (Japanese: ει³γγ―), also called Miku Hatsune, and officially code-named CV01,[2][3] is a Vocaloid software voicebank developed by Crypton Future Media and its official anthropomorphic mascot character, a 16-year-old girl with long, turquoise twintails. Miku's personification has been marketed as a virtual idol, and has performed at live virtual concerts onstage as an animated projection (rear-cast projection on a specially coated glass screen).[4]
Miku uses Yamaha Corporation's Vocaloid 2, Vocaloid 3, and Vocaloid 4 singing synthesizing technologies. She also uses Crypton Future Media's Piapro Studio, a standalone singing synthesizer editor. She was the second Vocaloid sold using the Vocaloid 2 engine and the first Japanese Vocaloid to use the Japanese version of the 2 engine. The voice is modeled from Japanese voice actress Saki Fujita.
The name of the character comes from merging the Japanese words for first (ε, hatsu), sound (ι³, ne), and future (γγ―, miku),[a] thus meaning "the first sound of the future",[2] which, along with her code name, refers to her position as the first of Crypton's "Character Vocal Series" (abbreviated "CV Series"), preceding Kagamine Rin/Len (code-named CV02) and Megurine Luka (code-named CV03). The number 01 can also be seen on her left shoulder in official artwork.
Development
Hatsune Miku was the first Vocaloid developed by Crypton Future Media after they handled the release of the Yamaha vocal Meiko and Kaito. Miku was intended to be the first of a series of Vocaloids called the "Character Vocal Series" (abbreviated "CV Series"), which included Kagamine Rin/Len and Megurine Luka. Each had a particular concept and vocal direction.[8]
She was built using Yamaha's Vocaloid 2 technology, and later updated to newer engine versions. She was created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone. Those samples all contain a single Japanese phonic that, when strung together, creates full lyrics and phrases. The pitch of the samples was to be altered by the synthesizer engine and constructed into a keyboard-style instrument within the Vocaloid software.
Crypton released Hatsune Miku on August 31, 2007. Crypton had the idea to release Miku as "an android diva in the near-future world where songs are lost."[9] Hatsune Miku was released for Vocaloid 3 on August 31, 2013, including an English vocal library.[10] She was the first Vocaloid to be developed by the company, following their
