Hi
I herd your shawy shawy, it's well pronounced and very clear and understable, and since most Arabic patient understand it then no problem, but I have to tell you that shawy shawy is a Dialect, and what I wrote is Clasical Arabic (this one is the official Arabic that we learn at school).
It's not easy to tell you how to pronouce the sentences using this alphabet, I ll try to record and send them to you. But if any one from this forum would like to record them before me then it's gonna be great.
You are welcome.
