THE SPEECH AND ARGUMENT’S STRUCTURE IN BARACK OBAMA’S SPEECHES USING THE TOULMIN MODEL: ANALYSIS OF ONE-WAY COMMUNICATION

The research focuses on a structural analysis of the speeches of Obama that uses
the Toulmin Model as the framework. The model helps to determine how
argumentative elements and persuasive strategies are deployed in his speeches.
Through the examination of Toulmin´s proposition components throughout the
different sections, the research targets revealing strategic approaches in Obama's
persuasion through rhetorical structure using the content analysis method. After a
complete examination, it was discovered that Obama's speeches adhere to the
Toulmin model, and from the result can be seen the claims and data/grounds are
present in all sections, particularly in the introduction, body, and conclusion. In
addition to that, the results prove the proposition of the thesis and evidence-based
approach to argumentation through the use of warrants and backings. In this,
qualifiers and rebuttals function to guard against counterarguments and captivate
the audience. In short, the simple model is preferable to the other model. The use
of all models highlights Obama's competency in constructing catchy narratives and
engaging a listening in different audiences by using structured communication
techniques manifesting in the complicated dynamics and politics of rhetorical
persuasion.
