CeVIO AI
Next-generation AI voice synthesizer for talking and singing voices.
About
CeVIO AI is the next generation of voice synthesizer software from the CeVIO Project, developed by Techno-Speech in cooperation with the Nagoya Institute of Technology. It uses deep learning to realistically reproduce voice quality, habits, and speaking and singing styles.
It offers both a Talk Editor for speech synthesis and a Song Editor for singing synthesis, with a wide library of character voice banks that can be switched between. Users enter lyrics and a melody to generate a clear, natural voice track, freehand-edit pitch patterns and timing, adjust volume and vibrato, and import MIDI and MusicXML sheet music data.
CeVIO AI is sold as editor-plus-voice starter packs and standalone voice libraries for Windows. It is commonly compared with VOCALOID, and its ecosystem includes popular voices such as KAFU and the BanG Dream! AI singing synthesizer line.
