Competent speakers must know the content of their speech and be able to effectively deliver that content.

A speaker can enhance their perceived competence by presenting a speech based in solid research and that is well organized and practiced. The two most researched dimensions of credibility are competence and trustworthiness (Stiff & Mongeau, 2003).Ĭompetence refers to the perception of a speaker’s expertise in relation to the topic being discussed. Ethos refers to the credibility of a speaker and includes three dimensions: competence, trustworthiness, and dynamism. Ethos, logos, and pathos were Aristotle’s three forms of rhetorical proof, meaning they were primary to his theories of persuasion.
