Biography

Koharu Rikka’s Synthesizer V voice comes from Yoshino Aoyama. The complete product includes Standard and AI databases: the former combines sampling and machine-learning methods, while the latter centres on neural synthesis. Both remain arranged by music creators.

Official demos include Digital $ Gold and originals or covers by different producers, showing the voice in varied music workflows. A separate CeVIO AI talk product exists; speech and singing editions should not be conflated.
