THE DIFFERENCE: INFORMATIVE VERSUS PERSUASIVE VERSUS AFTER DINNER SPEECHES
INFORMATIVE SPEECH–give us information that describes something or states how to do something; it does not give your opinion as a main point; it avoids making judgments that the things you are talking about are bad/good, etc.
PERSUASIVE SPEECH–persuade us to change our beliefs or actions; shows us YOUR opinion on a subject–that you think it is good/bad, right/wrong, moral/immoral, justified/unjustified, that we should/should not do something.
AFTER DINNER SPEECH–usually a persuasive speech but sometimes informative focused; key distinguishing feature is that it is focused on entertaining the audience usually with jokes and humor.
