CeVIO is the collective name of a range of computer software projects, including CeVIO Vision (digital signage), CeVIO Creative Studio (concatenative sampling–based vocal synthesis), and CeVIO AI (machine learning–based vocal synthesis). CeVIO was made to assist in the creation of user-generated content. It works via a text-to-speech method.

Overview

CeVIO is audio creation software for speech and singing vocal synthesis.

The Speech portion offers a large dictionary of words, which Sato Sasara, Suzuki Tsudumi, and Takahashi speak from, with accurate Japanese pronunciation.

Manual editing is also available, offering different types of voices for each character. It was created with the help of the HTS method.

This method is well known in the Vocaloid fanbase because it created the online synthesizers Sinsy, Open J-Talk, Renoid Player, and many more.

The software was initially released as "CeVIO Creative Studio FREE" with Sato Sasara as the only voice. Users were free to create tracks, insert lyrics, and add breaths to the end of notes, though they would get caught up in the end of her already automatically set breaths.

Anything else required external software but could not prevent the choppiness of her vowel transitions. After the release of "CeVIO Creative Studio S" on 14 November 2014, the FREE version was replaced by a one-month free trial of the full version. The free demo version was no longer available after 19 November 2014.

In the full version, more options for fine-tuning became available in the form of Fine-Tune Amplitude Timing, which allows the editing of the choppiness. Fine-Tune Amplitude Timing allowed for a change in pitch, pitch bends, vibrato, vibrato timing, volume and dynamics. Gender factor is also available, which makes the voice less or more mature.

The option to import MIDIs and .xmls is still present. The file extension has also changed from the free version's ".ccs" to ".csv".
