Sorry what is exactly your claim here? That it is legal to use and monetise off of someone else's voice? Using Morgan Freeman's or Joe Rogan's voice for example to host your podcasts?
I'm just pointing out that there is a lot of legal gray area when it comes to AI-synthesized voices and copyright. It still remains to be seen how the courts end up ruling.
What's the difference between using an AI voice and Bill Hader or Jimmy Fallon doing a celebrity impersonation on his show and monetizing that?
