This paper analyses contemporary trends in virtual idols circulated in East Asian popular culture. The precedent for this phenomenon is found in the Japanese “Vocaloid” software, developed in 2004, which allows users to synthesize vocal melodies, including lyrics, from purchased voicebanks, which are marketed as virtual “singers.” Mandarin- and Korean-language Vocaloid voicebanks have led to the creation of virtual idols representing Chinese and Korean popular cultural forms. In 2020 the virtual K-Pop idol "Naevis" was debuted, produced using generative vocal and visual synthesis, marking a departure from Vocaloid virtual singers who are produced using concatenative synthesis from credited voice actors.

In this paper, I use online ethnography of social media and private discussion forums to explore reception to Naevis among K-pop fans in East Asia, with a focus on how concealment of production in Naevis as an AI-generated idol compares to Vocaloid as a fan-made community. By using ethnography, I attend to the culturally encoded treatment of “authenticity” of vocal performance which has evolved in recent years through transnational cultural exchange across East Asia. In considering virtual idols and digital media, the discussion of authenticity in vocal performance is broadened. My paper highlights the ways in which fan communities use discourse and creative practice to make the virtual show up as a real and tangible cultural phenomenon. The comparative aspect of my paper serves to question the socio-technical conditions for virtuality that are shaped by both fan reception and cultural economies of East Asian entertainment industries.
