Hatsune Miku Development

After acquiring the Vocaloid 2 speech synthesis engine from Yamaha, Crypton Future Media began to develop their third Vocaloid. Hatsune Miku's voice was created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone. These different samples all contained a single Japanese phonic which, when strung together, would create full words and phrases. 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 program.

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."
