, sometimes referred to as
Miku Hatsune, is a humanoid
persona voiced by a singing
synthesizer application developed by
Crypton Future Media. Hatsune Miku is portrayed as a 16-year-old girl with long turquoise twintails. She uses
Yamaha Corporation's
Vocaloid 2 and
Vocaloid 3 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 sampled from Japanese
voice actress Saki Fujita. Hatsune Miku has performed at her concerts onstage as an animated projection.
