Being sure that it's really my son talking to me over the phone is primarily a communication problem, no? The social and political implications are quite large, but they can be addressed by solving the communication problem. This can involve crypto.

Or am I missing something?

(I say nothing for or against the particular scheme proposed by gp, just against parent's implied generalized dismissal of crypto to solve this problem)

Agree. I was just talking about a pure technical issue of voice synthesize, and its implications to voice encryption. In other words, a communication-over-the-phone problem. I didn't mention nor intended to talk from a political or social perspective.

While I understand the parent comment's stance that cryptography is not the magic sauce, I don't think it's related to my comment.
