I would argue it's fraudulent. There's loads of text to speech synthesizers that work just fine but sound robotic. The huge technological advancement of tihs technology is that it 'sounds human', even if it isn't.

LLMs are great, but we should stop bundling fake image generation and fake voice generation with it and calling it AI.

If you truly believe that there's no problem, and that it's fine, then use a TTS technology that didn't spend a gigajillion dollars on trying to sound like it's not what it actually is.

It's like selling soy pellets with synthetic meat flavour and making it look like meat and selling it in butcher shops and not clarifying that it's not actually meat.

On the one hand, I personally believe that meat is better, yes, but on the other hand, that's not what I am going to discuss and it's a disservice to argue about how meat is better, all you need to know is that if you try to pull this off, you will be indistinguishable from unethical fraudsters. Not saying you or Perforce are one at this point, we are all dazzled and confused by the technology, but down the line, when regulations settle in, there will be no gray area, do not do this shit if you care about your reputation. Only do this shit if you want to make quick bucks during during the boom and before the bust.
