You do realize that the vast majority of voice actors are not famous right?

Yes, that's the point. You are not defending voice actors by demanding likeness rights.

I am not sure why this is so difficult to understand. Maybe there is some confusion about the technology. You only need a few seconds of audio to clone a voice. You don't need hours of audio from a professional. That's why the tech can be used for scams. Likeness rights won't create jobs for voice actors. Only free money for famous people. You can also generate random voices.

Leading AI voice companies like Elevenlabs require you to have permission to clone a voice. But how can they check if their customers are being truthful? In practice, it simply means that famous people, whose voices are known, may not be imitated. Likeness rights, by their nature, can only be enforced, with any kind of effectiveness, for the rich and famous.

OpenAI tried to hire Johansson. When she declined, they hired a different, less famous actress. Maybe they did that to defend against lawsuits, or maybe it gives better results. If they had engineered a nonexistent voice, it would be almost impossible to make the case that they did not imitate Johansson. But still, everyone is talking about that poor famous, rich person who got ripped off. What about the actress who actually provided the voice? I guess she can look for another job, because Johansson owns that voice type.
