One technique I seldom see used is positioning in order to emphasize key points.
How it’s done
Before I begin, this is not to be overused. Someone who appears to be pacing throughout their speech is supremely distracting. The entire point of emphasis by positioning is that it’s unique. If you move around all the time, then it won’t seem special when you do it for an important argument.
First of all, you will start from a position either right by your lectern, or behind your lectern. Read this post if you still haven’t decided on that.
Next, when you are making an important point or explaining something essential, move from your natural position—far enough to make it very purposeful.
If the judge is looking down at their paper, they will most likely look up because they’ll notice that your voice is now coming from somewhere else. If they don’t, it’s a good idea to pause before starting that part. A longer than usual pause causes curiosity, and they will probably look up.
After you are finished explaining or making your point, return to your original position.
It may sound weird written down on paper, but when done correctly it will seem much more natural.
Example: you want to explain the big picture of how all your negative arguments combine. In this case, it’s important for the judge to really remember this. “I’ve gone through all the arguments, so I want to step back and show you the big picture of the debate round. [Move to the side and pause] [Explain the big picture] [Move back].”
If you have an idea that you need to explain and you have specific hand motions in order to do so (such as holding your hands out to illustrate size), this is also a good time to step to the side.
Emphasis by positioning is a useful tool for helping judges remember specific points.
If you haven’t read it already, read the post about saying bold things. When you do that, emphasis by positioning can help make it even more powerful.
