At firs, he seems a little insecure and doesnt appear to know his speech that well. He's constantly looking down at the paper and when he does he looks for too long, losing eye contact, and thus appeal and interest from the audience. Later on though, he becomes more confident and starts to sound more convinving and convinced about his arguments. He does have a certain degree of dynamism and proyection that do help him though, as the speech unfolds. He is clear in what he speaks, I dont have any trouble understanding.
