Watch these speeches

Take some time to watch these speeches.  For each speech make some notes on the structure of the speech and the techniques used.  Did the speaker use repetition?, did they ask questions?, what points did they make?, how did they make them?, did they have a conclusion?, did they use gestures?, did they use facial or voice expressions? Now think about your speech how can you make it just as effective?
