BanG Dream! AI Singing Synthesizer

, titled, is a project of the BanG Dream! franchise together with the voice synthesis software CeVIO AI.

Song Voice Libraries
The project features song voice libraries for POPY and ROSE. It was developed by Bushiroad, Inc. and released for CeVIO AI in 2022.

POPY
POPY (ポピー) is a character song voice based on Toyama Kasumi. While the design is based on Kasumi, POPY's song voice is meant to capture the sounds of the band Poppin'Party, hence her name being derived from the band's name. Her illustration was designed by yonemuro (米室).

ROSE
ROSE (ローズ) is a character song voice based on Minato Yukina. Similar to POPY, ROSE is meant to capture the sounds of the band Roselia, hence the namesake. She was also illustrated by yonemuro.
