Hi Steve.
Thank you for take Deukum class and I am happy to see you in the class.
It was first time for me to see your presentation.
I want to tell you several things you need to change for the better.
First of all, you have wrong pronunciations such as:
traditional, furnace, first, popularity, modern, creator, use, become, half (‘L’ has no sound) – please check these sounds at M-W.com neatly
Second, you used your mouth inefficiently. You are tried to open your wide but it is incorrect.
Try to use your mouth properly rather than just open widely.
For the better presentation, try to read a book slowly so that you can feel proper position of your tongue.
And plus, please listen to the same audio file 30 times more upon check my comments. It will positively affect for your study.
Thank you for make a presentation again.
If you cannot understand or confused, feel free to come and ask me.
