What CeVIO AI is
CeVIO AI is Windows software for synthesizing speech and singing for dialogue, narration, and songs. Talk voices can be adjusted for volume, speed, pitch, voice quality, intonation, and emotions. The song editor handles notes and lyrics, with controls for timing and pitch. Exports include WAV, MIDI, MusicXML, and CCST, and MIDI support is available. Talk synthesis can connect through SAPI5, a COM component, or a .NET assembly. These interfaces work with only one application at a time, cannot be used with song-only products, and SAPI5 compatibility does not guarantee operation in every compatible application. Commercial use through the external interfaces is not allowed. CeVIO AI requires Windows 11 64-bit, a dual-core Intel or AMD processor, 4 GB RAM, and 1 GB storage. Internet access is required for activation and updates, with one license per PC. After online startup, offline use lasts up to 365 days with some functions restricted.
