ELI5: Why does hearing yourself speak with a few seconds of delay, completely crash your brain?
gpt
It's called speech jamming.

Your brain pays a lot of attention to that what you say comes out right - you are listening to yourself as you speak.

With just a tiny bit of delay your brain percieves it as what just left your mouth, it's no issue, otherwise room echos would jam us all the time.

But is the delay too long, what the brain hears doesn't match up with what goes out through your mouth. So it tries to adjust your speech for the mismatch and that essentially creates a feedback loop and you're jammed.
