I would suggest starting with a text to speech to help perfect your Arabic. I've used that to help perfect my French and make sure that I am saying things correctly. Also, there are apps that are specifically meant to help with conversations! I know that my girlfriend used one before she studied abroad in China. (although unfortunately I can't think of the app off the top of my head). I wish you luck in your Arabic studies! Be patient with yourself and you'll be able to achieve your goals!
