Automated greeting using non-human voice

This is going to sound a little nuts but with the rise of deep fakes and AI voice impersonation, I would like the ability to initially screen a call using something other than my actual voice.

In other words, I get a ton of calls from potentially valid numbers but the vast majority of them end up being from a call center in a foreign country. I'd like to be able to basically say 'Hello, how can I help you?' using a computer voice. I would also like to be able to say, "Thanks but I am not interested." in that same voice. (The latter is optional. I could just hang up on them.)

Sure, you might say, how often does that happen? It is A LOT.

Honestly, in a perfect world, we could alter our voices and speak with the person through a filter until we know that we can trust them.

I swear in my soul that I am not currently wearing a tin foil hat.
