Hatsune Miku (初音ミク), sometimes referred to as Miku Hatsune, is a humanoid persona voiced by a singing synthesizer application developed by Crypton Future Media. Hatsune Miku is portrayed as a 16-year-old girl with long turquoise twintails. She uses Yamaha Corporation’s Vocaloid 2 and Vocaloid 3 singing synthesizing technologies. She also uses Crypton Future Media’s Piapro Studio, a singing synthesizer VSTi Plugin. She was the second Vocaloid sold using the Vocaloid 2 engine, and the first Japanese Vocaloid to use the Japanese version of the Vocaloid 2 engine. Her voice is sampled from Japanese voice actress Saki Fujita. Hatsune Miku has performed at her concerts onstage as an animated projection.
The name of the character comes from merging the Japanese words for first (初 hatsu), sound (音 ne) and future (ミク miku), thus meaning “the first sound from the future,” referring to her position as the first of Crypton’s “Character Vocal Series.”
Hatsune Miku was developed by Crypton Future Media, using Yamaha’s Vocaloid 2 and Vocaloid 3, along with her voice being created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone and those different samples all contain a single Japanese or English phonic which, when strung together, create full lyrics and phrases and as a result, the pitch of the samples was to be altered by the synthesizer engine itself, and was constructed into a keyboard style instrument within the Vocaloid 2 and Vocaloid 3 programs.
Crypton released the first of their “Character Vocal Series”, 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.” Hatsune Miku was released for Vocaloid 3 on August 31, 2013, including an English vocal library. She was the first Vocaloid to be developed by the company, following their commercial release handle of Yamaha Corporation developed vocals “Meiko” and “Kaito”, making her the third Vocaloid to be sold commercially by the company.
