Megurine Luka

Megurine Luka (巡音ルカ Megurine Ruka), sometimes referred to as Luka Megurine, is a humanoid persona voiced by a singing synthesizer application developed by Crypton Future Media, headquartered in Sapporo, Japan. She uses Yamaha Corporation's Vocaloid 2 and Vocaloid 4 singing synthesizing technology. Her voice is sampled from Yū Asakawa. She has performed at live concerts onstage as an animated projection. Luka was developed by Crypton Future Media using Yamaha's Vocaloid 2. Her voice was created by taking vocal samples from voice actress Yū Asakawa at a controlled pitch and tone.

Megurine Luka was originally designed to be the first Vocaloid of the Character vocal series that Crypton Future Media would release and was going to be called "Hatsune Miku", designed to be capable of both English and Japanese vocals. However, the concept was put on hold and the name was used for another character, making Luka the 3rd vocal of the Character vocal series to be released instead.
