Persuasive speeches aim to convince the audience to believe a certain view.
Persuasive speeches can be designed to convince, incite action, or enhance belief by the audience.
Informative and persuasive speeches differ in what they want the audience to walk away with: facts or an opinion.
Each individual is persuaded by different things over different time-periods, so to be effective each pitch must be customized.
Persuasion is unethical if it is for personal gain at the expense of others, or for personal gain without the knowledge of the audience.
