Vocaloid, Vocaloid2 and Vocaloid3 are voice synthesizing applications, they have been commerically sold since 2004 and began from one of the simplest ideas of synthesizing the human vocals for singing. From the start this was never a easy task for the programmers behind the software, but from that beginning to what we have now Vocaloid has grown into a synthesizing phenomena who has spawned new musicians, albums, figurines and even concerts.
