What CeVIO AI is
CeVIO AI is Windows software for creating synthesized speech and singing for dialogue, narration, and songs. Talk voices have controls for volume, speed, pitch, voice quality, intonation, and emotion. The song editor supports note and lyric editing, along with adjustments to singing parameters such as timing and pitch. Listed export formats are WAV, MIDI, MusicXML, and CCST, and MIDI support is available.
Talk synthesis can connect to external software through SAPI5, a COM component, or a .NET assembly. These interfaces cannot be used with song-only products, allow only one application at a time, and do not permit commercial use; the maker directs business users to contact it. CeVIO AI is a 64-bit application and cannot directly integrate with 32-bit external software. Requirements include Windows 11 64-bit, a dual-core Intel or AMD processor, 4 GB RAM, and 1 GB free storage. Internet access is needed for activation and updates, and each license works on one PC. After an online start, it can be used offline for up to 365 days, but some functions are restricted when starting offline. There is no free plan; listed one-time products cost 10,780円(税込), 16,980円(税込), and 19,580円(税込).
