The best suggestion would be listening and watching Korean movies and TV shows. If you watch a Korean person speak, they move their mouths differently when they want to put more emphasis, say something cute etc. If you mimic how they speak that would be helpful. Then listen to them, close your eyes and listen to where the 'stress' points are. I find, generally, Korean people pause with grammar points (just my observation); when they use ~고, ~는데, ~지만, ~잖아 This when I commonly hear it. You want to listen to the 'rhythm' of the language. Hope this helps
