You should not be able to use someone else’s biometrics (voice is one) to generate content without their consent. Your example would be similarly illegal because it is unethically using a persons personal data without their consent for commercial or other purposes.

It’s “novel” in that it’s an approximation of all its input data, tweaked to match the specifics of the request given. It still needs to use the data of real people or it can’t create anything. You have a surface level understanding if you don’t understand the importance of that seeding data.

You don’t seem to value consent when it comes to the systematic harvesting of personal data for another persons benefit. I’ve been very clear that the issue is the lack of consent combined with current and future capabilities of the technology.
