The pause after a question or important point. I had a professor who would color code his powerpoint lecture points and had a very distinct accent. He would stop and point at the important points, which were in red, "is this in red? is this important? could you see this in a test question worded like this? could you see this in a test question worded like that?" It was an accelerated course and we all passed with flying colors due to his teaching methods. You would literally hear his voice in your head while taking the exam and see the test question in a way he mentioned.
