Trained on the Mature Register
Crypton designed Luka as a 'moody, soft' voice — Yū Asakawa's husky mezzo gives the CV series its most experienced-sounding singer.
Vocaloid's Bilingual Siren
Luka Voice Changer
Megurine Luka is CV03 — the final member of Crypton's Character Vocal Series, released January 2009 with a voice that broke the mold. Where Miku sparkles and the Kagamines bounce, Luka sings low, warm, and husky, courtesy of voice provider Yū Asakawa — and she made history as the first English voicebank produced by a Japanese company. The Dubbing AI Luka voice bottles that mature, slightly world-weary register for covers, karaoke nights, and every callout that deserves more soul.
