We don't need code words, we need a proper PKI (public key infrastructure) for authenticated communication.
- You receive a call from an unknown number and they tell you they've kidnapped your wife. They then give her the phone so you can hear her but she didn't do it through Signal so she's obviously not your wife so you just hang up.
  
  You can use this to your benefit though
  husband/wife walks up to you to start an argument
  "sorry honey, you need your public key"
  Instant win
- Seems a bit hard to verbally exchange keys and sign your speech though.
  
  Yeah, I wouldn't recommend doing that.
  And that's not how you establish a PKI or implement AE (authenticated encryption). When I send a voice message e.g. I don't verbally sign it, that's actually part of KE (key exchange) protocol.
  Same applies to non encrypted, authenticated communication of course.
  And in case you are talking about physical face to face communication: I think you'd recognize your family and friends without the help of cryptography.
  Edit: if you have any question, feel free to ask! Maybe I misunderstood you? Then I'm sorry
  
  Of course you don't verbally sign voice messages. That wouldn't make any sense at all unless you are a robot or something.
  It was just a joke. But if you wanted to authenticate something (like an email, or voice I guess) in a PKI you would sign it using your certificate private key and the CA would tell the recipient if it's valid or not.
  
  That's what the article is about though, voice messages can now be spoofed. It happened to one of my friend's parents
  
  I was implying that you do the actual singing verbally. Like actually saying the bits, which would be pretty much impossible.
  Of course you could sign voice messages. That would be like singing any other file.
  
  Ohh
