Vocaloid is a technology for singing voice synthesis developed by Yamaha, and the name of this software application. The software allows users to input melody and lyrics in order to synthesize singing. In other words, with this technology, singing can be produced without a singer.
Singing voice synthesis is produced by using fragments of voices recorded from actual singers, called the Singer Library. By changing this Singer Library, various voices such as Miku Hatsune and Gakupoid are able to be created. There are countless musical pieces that have been uploaded to Nico Video and Youtube that use these products.

In addition

In addition, songs that used Miku Hatsune and videos that were uploaded on Nico Video became extremely popular, and the UGC (self-produced content) grew at a fast pace. From there, CDs with Vocaloid songs entered the top-sellers lists, became popular songs for people to sing at Karaoke, and the software and music created from it have become a music culture in itself.

Vocaloid technology

Vocaloid technology has improved dramatically and the expressions and audio quality of Vocaloids have improved to the point where it's hard to tell the difference between them and living human beings. Not only does it allow for users to easily create songs and cover songs for their enjoyment, but it is progressing to allow users to make full-scale musical pieces as well.
Furthermore, there are little restrictions on hardware as long as they are connected to the internet, so there are many possibilities for future uses including for mobile phones and portable game machines.

The future

The future of Vocaloid is one in which it will become as natural as playing a piano; a platform that provides a spotlight for musical creators. Vocaloid will spread and reach more and more people, who will in turn find new ways of enjoying its possibilities. We hope that it becomes an indispensable aspect of the music industry.
