Big Hit Entertainment is pouring money into artificial intelligence. The company behind K-Pop megastars BTS has announced the investment of 4 billion KRW (approximately $3.6m) into a Korea-based Artificial Intelligence company called Supertone. Founded last year, Supertone claims to be able to create "a hyper-realistic and expressive voice that [is not] distinguishable from real humans". Could Supertone soon create "hyper-realistic and expressive" clone voices for BTS members themselves – allowing Big Hit to record BTS vocals (or, more likely, BTS-narrated ads, video games etc.) without the band even being in the room? The evidence suggests it's not beyond the realms of possibility.
