CeVIO is the collective name of a range of computer software projects, including Vision (digital signage) and Creative Studio (audio creation software). CeVIO was made to assist in the creation of user-generated content.[3] It works via text-to-speech method.
It allows audio creation software for speech and voice synthesizing. Speech and Song are this program's main features. The Speech portion offers a large dictionary of words to which Sato Sasara, Suzuki Tsudumi, and Takahashi speak from and are accurate in the Japanese language, although the option to manually edit it exists as well. The Speech portion was created with help of the HTS method. This method is famous in the VOCALOID fanbase because this method created the online synthesizers Sinsy, Open J-Talk, Renoid Player, and many more. The Speech portion offers different types of voices for each character.
CeVIO Creative Studio's speech intonation can be controlled with three parameters: cheery, angry, and sad. Other things can be controlled as well, such as volume and speed of consonants and vowels.
The software was initially released as "CeVIO Creative Studio FREE" with Sato Sasara as the only voice. One was free to create tracks, insert lyrics, and add breaths to the end of notes, but even then those would get caught up in the end of her already automatically set breaths. Anything else would require external software but didn't really stop the choppiness of her vowel transitions. After the release of "CeVIO Creative Studio S" on the 14th of November 2014,[4] the FREE version was replaced by one-month free trial of the full version. The free demo version was no longer available since November 19, 2014.
In the full version, more options for fine-tuning became available. Fine-Tune Amplitude Timing, which allows editing of the choppiness. In addition to pitch, pitch-bends can now also be adjusted, along with vibrato, vibrato timing, volume and dynamics. Gender factor is also available, which makes the voice less or more mature. The option to import MIDI's and .xml's is still present. The file extension also has changed from the free version's ".ccs" to ".csv".
In 2013 it won the MicrosoftⓇ Innovation Award 2013 award.[12] It also won an award in the CEDEC Awards 2013 event, after receiving 300,000 downloads.[13]
