@Jessica Shields thank you Ms Jessica. Your correction is valuable to me. The R sound puzzles me a bit. I think it is my bad habit doing this R in the wrong way for a long time. The other vowels, yes, I agree with you completely. Last night I record my self talk slowly and I see most of my words the vowels tends to be back in somewhere near my throat. I think maybe because I was thinking someways to Make my voice deeper so I fall into that trap. I definitely will work on these. Thanks again.
