> then you also have to accept that your voice is hopelessly copyable and defense against that is futile.

I kinda agree, still worth it to mention to your family or whatever some kinda safe word or whatever. I speak several languages so I guess any scammer impersonating me would focus on one, but who knows you can also make it speak any language I guess.

In order to be safe you'll have to pre-establish a safe word only you and the other person know in order to avoid fake scams etc
