Biography

CeVIO’s tenth-anniversary retrospective dates Sasara’s first appearance to an Akihabara store display in January 2013. Free speech software followed, then singing and speech in the commercial CeVIO Creative Studio that September, establishing a character through which users could make audio works.

CeVIO AI renewed her singing and speech products in 2021. She also moved onto virtual music stages, sharing a first co-headlining concert with Suzuki Tsudumi in 2022. Its announced format combined onscreen characters with a live band, connecting software creation to concert production.
