CeVIO AI singing synthesizer: features and spec-based rating

CeVIO’s CeVIO AI is software with a song editor, in which AI voices sing, and a talk editor, which makes voices speak. It runs on Windows.

A singing synthesizer is a tool that sings for you when you enter lyrics and a melody on a computer.

In this article we compare CeVIO AI with 7 singing synthesizers and rate how well it serves its purpose on three criteria. The basis is official manufacturer information.

Summary

Among the 7 singing synthesizers, CeVIO AI is rank C. The ranks run S, A, B and C, and C is the lowest. Averaging the scores for the three criteria (out of 5) gives 2.3.

Things to keep in mind

• Languages it can sing (2 points): the number of languages it can sing is small.
• Where you can use it (2 points): the environments you can use it in are limited.

Who it suits: people on Windows who want their favorite character’s voice to sing in Japanese.

Main features of CeVIO AI

A song editor with AI singing voices

CeVIO AI is software with a song editor, in which AI voices sing, and a talk editor, for speaking voices. In the song editor you enter a melody and lyrics and have a song voice sing. Song voices are bought and installed separately. The VoiSona official page also says that voice libraries made for CeVIO AI cannot be used in VoiSona, which uses the same line of technology.

Used on Windows

The supported OS is the Japanese or English edition of Windows 11 (64-bit). The song editor and talk editor are installed with a shared installer, and you activate the licenses of the editors and voices you bought to use them. The serial number is in the box for the packaged edition, and on the site where you bought it for the download edition.

A guide to the computer you need

The CPU should be dual-core or more (4 cores or more recommended) and memory 4 GB or more (8 GB or more recommended). If processing cannot keep up, sound may drop out during playback, but the manufacturer explains that exporting to a file is not affected. At least 1 GB of free space is needed for installation.

Where it is useful

• Having a song voice sing a Japanese song
• Making singing and speaking voices together with the talk editor
• Starting with a singing synthesizer on a Windows computer

Each criterion is scored from 1 to 5 on how well the product serves one goal: making a singing voice from a melody and lyrics. Scores follow the conditions in the table above. They are criteria chosen to match common searches about AI, singing in English, and whether it works on a Mac or a phone. The basis is official manufacturer information (official sites and manuals) and the Plugin Boutique product page. How natural the voice sounds has not been compared by ear, so it is not scored. Price and the number of voices are not part of the score. Features that cannot be confirmed from the manufacturer's or a retailer's description are scored as if absent.
