Japanese magazines such as DTM magazine are responsible for the promotion and introduction for many of the Japanese Vocaloids to Japanese Vocaloid fans. Yamaha themselves do maintain a degree of promotional efforts in the actual Vocaloid software, as seen when the humanoid robot model HRP-4C was set up to react to three Vocaloids-Hatsune Miku, Megpoid and Crypton's noncommercial Vocaloid software 'CV-4Cβ'-as part of promotions for both Yamaha and HRP-4C at CEATEC in 2009. Though developed by Yamaha, the marketing of each Vocaloid is left to the respective studios. Crypton had the idea to release Miku as 'an android diva in the near-future world where songs are lost.'

Ĭrypton released the first of their 'Character Vocal Series', Hatsune Miku, on August 31, 2007. 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. These different samples all contained a single Japanese phonic which, when strung together, would create full words and phrases.

Hatsune Miku's voice was created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone. After acquiring the Vocaloid 2 speech synthesis engine from Yamaha, Crypton Future Media began to develop their third Vocaloid.
