UTAU is a vocal synth program created by Ameya/Ayame in 2008. UTAU is similar to the VOCALOID software, with the main differences being that it is shareware instead of under a third party licensing, and anybody can make a singer. To make an UTAUloid, a user would record samples of themself talking/singing strings of syllables in almost any language. These collections of recordings are referred to as a voice library or voicebank, which can then be used through the UTAU program.
This program was initially develpoed as an April Fools prank, as a parady VOCALOID (hence why it is commly refered to as UTAUloid), but is used now rather commonly due to the program being free. Some of the more popular UTAUloids include: Teto Kasane, Uta Utane, and Momo Momone. This website contains info on alot of these Vocaloids, and UTAUloid another similar program.
