"Give me 20 seconds, the answer is loading. I have a stutter and proper nouns sometimes trip me up, my mouth isn’t ready yet." I'm thinking of carrying a card saying that. I can just show it if it's one on one conversation. If I'm talking to multiple people, I can make an AAC app say it out loud instead of showing it. I'd also add "If I make facial grimace, that means the answer is loading." to my card.
