This week, Hatsune Miku, the Japanese singing hologram appeared on the David Letterman show, which is a surprise on so many levels.
Hatsune Miku was developed by Crypton Future Media, using Yamaha’s Vocaloid 2 and Vocaloid 3. Hatsune’s voice was created by taking vocal samples from voice actress Saki Fujita at a controlled pitch and tone. These different samples all contained a single Japanese or English phonic which, when strung together, would create full lyrics and phrases. The pitch of the samples was to be altered by the synthesizer engine itself, and was constructed into a keyboard style instrument within the Vocaloid 2 and Vocaloid 3 programs.
