Having dyslexia makes communication harder, because sometimes in stressful situations you can easily trip over your own words. But it can easily be done if you're talking to a friend or family. I have accidentally done a spoonerism to some comedic effect in front of people and in important calls.

It's an easy mistake to make but if people know you have dyslexia and accept that it can happen, then it's okay. But in a formal interview it might be hard to speak and not trip over your own words. There would advise you to look online to help you with these, but I cannot give you any since I will avoid interviews like they were a plague. I have had interviews and given them, both are still nerve wrecking.

I remember my GCSE’s and the issues they brought up as well, reading the exam question were harder than normal due to the stress. The words could easily just jumble up and you misread the question is a possibility. But just relax and keep calm as you go through the exam.

There have been times I've become “word blind” (my own phrasing there) where I've been reading for fun for too long and the words just blur out and kind of lose their meaning. When it starts, I stop and try to do something else.

But communication with or without dyslexia and/or autism is a difficult thing in general, with both it feels like someone has upped the difficulty.
