Octavia (オクタヴィア) is a voicebank for the UTAU software.


Octavia's first voice bank, Octavia CVVC, was recorded in August 2020.

There are plans for more voice banks and updates.


Octavia is a timid, quiet person who often keeps to herself. She's basically mute without Joule, her older brother, to help speak on her behalf by whispering into his ear. Otherwise, she is fully comfortable talking to Joule one-on-one. Despite her shyness, she enjoys singing and writing short poems.

(NOTE: this is just CJ's portrayal of Octavia as a character. Headcanon's are welcome!)
