An unofficial CeVIO AI User Manual English translation.

CeVIO AI is the next generation of voice synthesizer software, developed by Techno-Speech. It uses the latest AI technology to create high-quality voice tracks from speaking to singing, capable of expressing different types of voices, personality traits and singing styles.

This website is an unofficial translation of the CeVIO AI User Guide, as the official manual, although thorough, is only available in Japanese.

This website is not affiliated with Techno-Speech.

The user manual is separated into sections following the origin version.

Desktop users can navigate using the top menu, and mobile users can tap the three-bars () icon in the top left corner to open the navigation menu.
