I'm at the very beginning of learning and trying to start with the alphabet, I try to hear to those letters again and again to understand the difference, but the moment they change word (like using a different word with the same letter) I can't understand the differences anymore. I know that part of it is just getting used to understand the differences by listening to things over and over, but what if I don't really hear the difference? Not hearing the difference ofc brings me to not being able to pronounce things correctly too
