>Why can’t I be fluent when talking to a bot? Is it because I imagine her as a person or it is just the pressure of saying something clearly? That's actually an interesting case you've got there. I suppose you're in a situation where it's important that you speak in order to be understood - as in, there's something that needs to be delivered clearly, yes, and there's something that needs to happen based on that delivery. That's the same "mode of communication performance" as when dealing with real people, we might say.
