I think a more interesting (and less dubious) example of this would be Vocaloid and to a greater extent, cevio AI

Vocaloid is a synth bank where instead of the notes being musical instruments, they’re phonemes which have been recorded and then packaged into a product which you pay for, which means royalties are involved (I think there might also be a thing with royalties for big performances and whatnot?) Cevio AI takes this a step further by using AI to better smooth together the phonemes and make pitching sound more natural (or not - it’s an instrument, you can break it in interesting ways if you try hard enough). And obviously, they consented to that specific thing and get paid for it. I mean obviously that consent doesn’t go beyond the voice bank (a lot of voice providers are established VAs and singers), but that shouldn’t be too hard to understand, right?

(There’s also FOSS voicebanks but that adds a different layer of complication to things like I think a lot of them were recorded before the idea of an “AI bank” was even a possibility)
