Abstract:This paper is going to make an extensive study on Obama’s victory speech from mainly three layers—word-level statistics and analysis, sentence-level statistics and analysis and some unique characteristics displayed in the discourse. The author will adopt the method of quantative discourse analysis, or to use explicit statistics, charts and comparative figures to analyze the whole text with readers in order to achieve such effects as follows: first of all, to help readers get a better grasp of this speech discourse—the main content and theme the deliverer wants to convey. Then readers are supposed to understand how these effects are achieved and what tactics are employed in it. Last, a conclusion of the whole paper will be given and the significance of this analyzing method, which perfectly combines liberal arts with a relatively scientific thinking method, will be discussed.

Key Words: Discourse Analysis, Quantative Analysis, Statistics, Significance

From all the discussions above, the first prize should be a deeper understanding of the victory speech. By adopting these three levels of analysis, namely, the word-level, sentence-level and some other unique characteristics displayed in the speech, we are now clear about his diction such as certain nouns and verbs and the function of each of them. Furthermore we are clear about the prevailing sentence patterns employed in it like imperative or short sentences and their respective effects. Also we are clear about some unique points related to Mr. Obama himself such as his origin and those relevant issues. Now we can fully understand why Obama has to present the speech in such a way and all the tactics used in it and more importantly, what kind of effects these tactics could achieve.
