A vocaloid character
Hatsune Miku (初音ミク?) is a singing synthesizer application with a humanoid persona, developed by Crypton Future Media. It uses Yamaha Corporation‘s Vocaloid 2 and Vocaloid 3 singing synthesizing technology. 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. Hatsune Miku is portrayed to be a 16-year-old girl with long teal pigtails.
