Singer Zubeen Garg's voice will be digitally preserved to prevent unauthorised use. "With AI-generated software...it's...possible that Zubeen's voice samples...could be used by others...as their own," singer Manas Robin, a long-time associate of Garg, said. "We'll work on...creating...such a 'digital signature' that the moment his vocals are played...origin can be detected," he added.
