KAITO and Hatsune Miku are vocaloids. Vocaloid is a singing synthesizer application software developed by the Yamaha Corporation that enables users to synthesize singing by just typing in lyrics and melody. KAITO is a Vocaloid DTM (Desktop Music) software created by Crypton Future Media. He utilizes the older Vocaloid engine, the predecessor for Vocaloid2. The voice was supplied by Naoto Fuga and the name “KAITO” was selected from among applicants. He is fit to sing anything from hymns and children's songs to R & B and pop, though the style that he is best used for is singing pop ballads. Miku Hatsune (初音ミク Hatsune Miku) is the first installment in the Vocaloid2 Character Vocal Series created by Crypton Future Media and the most popular and well-known Vocaloid, released on August 31, 2007. The name of the title and the character of the software was chosen by combining Hatsu (初, first), Ne (音, sound), and Miku (未来, future) thus meaning the first sound to the future. The data for the voice was created by actually sampling the voice of Saki Fujita, a Japanese voice actress. Unlike general purpose speech synthesizers, the software is tuned to create J-pop songs commonly heard in anime, but it is possible to create songs from other genres. Read more on Last.fm.
