Should I casual English exercise?

I explained to you in my last entry my difficulties understanding casual English. That means my pronunciation isn’t the best, and I told you that my grandkids were able to understand everything, while I was only able to understand half of what had been said. That means it was more random than based on actual understanding. But now I tried to do the test again, and I found out that the situation hasn’t changed. This kind of pronunciation is still too difficult for me, so I put it to ChatGPT, and ChatGPT understood everything. That’s its power of guessing the meaning, I think. And so there’s a big difference between better English speakers and me. I’m not able to understand more or less difficult pronunciation. But I need a lot of self-confidence to take on my English learning process, so I had a long talk with ChatGPT about casual English, and I found out that the corrections by ChatGPT weren’t quite suitable in many cases. They didn’t match my intention, so I discussed with ChatGPT about stopping this kind of learning casual English  and trying to develop my own English sound by practicing, not by exercising. That’s my recognition at the moment, and I hope it will help.
