i swear to god people need to learn the difference between ai generated voice and vocal synth. mastering the art of a vocal synth is hard. you have to tune that shit yourself. you have to edit the vocals and do it all yourself. it takes hours to get a synth to sing a song well. when people make covers of songs with miku they are not just imputing a song and boom she sings it. not like how people do with ai. also, vocal synths were created specifically to assist musicians who struggle with finding vocalists (hiring a vocalist is fucking expensive) or cant provide vocals on their own. vocal synths are instruments and tools that one needs to learn and master, and they get their voice providers from people who 100% consented to having their vocals used. hatsune miku is not ai. using vocaloid or synthv or utau is not anything like lazily ai generating a voice at all. grow the fuck up.
For anyone who hasn't looked at vocaloids since 2012, Teto Kasane, one of the most famous UTAUs, just got her first commercial voicebank for her 15th anniversary.
