Hatsune Miku
, sometimes referred to as Miku Hatsune, is the name of a Vocaloid software voicebank developed by Crypton Future Media and its official moe anthropomorph, a 16-year-old girl with long, turquoise twintails. She uses Yamaha Corporation's Vocaloid 2, Vocaloid 3, and Vocaloid 4 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 modeled from Japanese voice actress Saki Fujita. Miku's personification has been marketed as a virtual idol and has performed at concerts onstage as an animated projection (rear cast projection on a specially coated glass screen).
Vocaloid 2
Megurine Luka was the third and final member of the Character Voice series. She was noteworthy for being the first vocal capable of both English and Japanese speech. She was released on January 30, 2009, and was codenamed "CV03" prior to release. Her English vocal initially did not have a full library and was capable of only 2,200 words, though she was later updated to fix the problem. It is notable that her package was originally going to be called "Hatsune Miku", designed when Vocaloid 2 was first announced to be a bilingual English and Japanese vocal, being the first planned member of the Character Voice series. Her provider is Yū Asakawa.
