I haven't read the actual law, but the description of it sounds like it's limited to things like imitating an artists voice. Certainly it makes sense to not allow a recording that claims to be Luke Combs singing, oh, say his new song "Fast Car"[1]. But, does it mean one couldn't create a voice that sounds a lot like Luke Combs as long as it's well labelled as AI-generated?
[1]Yes, I know it's a Tracy Chapman song.
