LEON, a VOCALOID-compatible singing voice synthesis software, was first released in 2004.
LEON (male voice) and LOLA (female voice), among the very first VOCALOID products, were developed in the UK and are designed for English, but it seems some producers have devised ways to make them sing in Japanese as well.
The voice source is said to be a British soul singer, but LEON can handle a wide range of genres beyond soul.
It was originally developed with the goal of handling backing vocals, but nowadays a scene has formed where Vocaloids sing as the main vocals.
Now then, please listen to the singing voice of LEON, the origin of Vocaloid.
