VOCALOID and its succeeding versions are voice synthesizing applications that have been sold commercially since 2004. VOCALOID began from the simple concept of synthesizing the human vocals for singing. From the start this was never an easy task for the programmers behind the software, but from that beginning VOCALOID™ has grown into a worldwide phenomenon, spawning new musicians, albums, figurines and even concerts. There are many different VOCALOIDs, such as GUMI, Fukase and Haruno Sora, who sing in Japanese. There are also VOCALOIDs like L♀LA, BIG AL and AVANNA, who sing in English. As of VOCALOID3 there are now VOCALOIDs like Bruno and Clara, who are Spanish, while VOCALOID4 has UNI who is Korean and Luo Tianyi who is Chinese.
