RUBY

Ruby is an upcoming English VOCALOID to be developed for the VOCALOID4 engine by VocaTone.

Concept
Ruby is based on a female singer with a standard American accent. Her developer hinted that the voice provider was not white, which may have influenced the design.

When the character design was revealed July 4, 2015, Syo stated that PowerFX had gone against his wishes. He and Natasha had been working on a final design for nearly a year, however he felt PowerFX must have changed the art to appeal to an EDM audience, despite promising Syo control over the design. The image had been concealed from the developers until launch.
