Expressing Emotions in Speeches

Here is a link from the website of a public speaking club. It's interesting to think about how speakers use non verbal communication to express emotions in their speeches. They'll criss-cross the floor quickly and shake their hands when they're excited, they might slam a fist down on the podium or point to the audience when they're being serious, and they're likely to smile and gesture largely if they're saying something comical. This kind of non-verbal communication reinforces what they actually say and helps to engage the audience.
