VOCALOID

"VOCALOID" is a singing synthesizer produced by the YAMAHA corporation. You enter the lyrics of a song into the program, add music, and then you can have one of the Vocaloids sing for you. Some of the vocaloids are MEIKO, KAITO, Hatsune Miku, Kagamine Rin, Kagamine Len, Gumi Megpoid, Kamui Gapuko, and Megurine Luka. Vocaloid is neither an official Anime or Manga. It is only a singing software.
