> I cannot understand when I mispronounce words. I get corrected often and repeat back the correction but it sounds like what I said the first time.

I have the exact same problem.

I had troubles learning pronunciations when I was a kid, but I never had other learning problems.

As an adult, I struggled enough with pronunciation that I consulted two hearing specialists to determine if there were any issues with my ears. It turns out my hearing is fine.

Is it possible for someone to get a diagnosis for dyslexic based on pronunciation problems only?

I must say I am relieved to finally find someone who shares my experience.
