CeVIO AI is Japanese voice synthesis software that creates singing and speaking voices using deep learning. Official CeVIO news covers software updates and new voice libraries from third-party makers. Recent releases include a song voice built from newly recorded singing by voice actor and singer Sachika Misawa, and an English talk voice for Soyogi based on the voice of Yuki Kaji. Each library is activated with a serial key inside the application.
Songwriters, video makers, game developers, virtual singer fans and vocal synthesis hobbyists are the natural users. The software is aimed at people who produce music or narration in Japanese, and English talk voices are now available as well. A Windows 11 64-bit computer is required, since Windows 10 support ended in October 2025. Creators who want a particular voice choose from character voice libraries, and CeVIO publishes a user guide and licensing information for characters and voice data usage.
Typical projects include composing songs with a synthesized singer, narrating videos with a talk voice, and building character content around a licensed voice. Third-party libraries add new options: Hako-niwa Hano and Koto song voices arrived in January 2025, and the Futaba Minato song voice launched in March 2026 with an emotion parameter called the wanpaku parameter. Starter packs bundle both song and talk voices, and some physical editions include a license for VoiSona Talk Lite, which works only in VoiSona Talk. Troubleshooting notices walk through reinstalling and re-entering serial keys when a voice fails to load.
