You can get that from me by calling and asking if Henry is there. I will answer "No, I'm sorry, but you must have the wrong number". Cheap with Twilio.
If they have access to your pictures, they have access to your videos. This matters because people don't think audio is being recorded when they take photos. As far as threat modeling goes, creating a cloned voice is something these apps could have already done.
If you accept that as true then you also have to accept that your voice is hopelessly copyable and defense against that is futile. So it’s not really important.

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
