The different types of persuasive speeches are definitional speeches, factual speeches, value speeches and policy speeches. These types of persuasive speeches revolve around the claims that are made in each of the speeches.
In a definitional speech, the speaker will talk about the definitions of different components. The speaker will often define words and compare them to each other. An example of a definitional speech would revolve around the difference between a massage service and prostitution. Both terms to persuade the listeners that a massage service is not considered a form of prostitution.
Factual speeches function similarly, but focus around claims that are known to be true. These claims can be backed up with recent research and accurate data from a reliable authority as well as by facts commonly known by listeners.
A value claim is nearly the exact opposite of a factual claim. The speaker will attempt to convince listeners that his or her personal value judgment is true through the use of language and wording.
Policy speeches are meant to persuade the listener that a policy should be implemented. A policy is defined as a clear solution to a type of problem with an established justification, plan and benefits. For instance, a policy claim in a persuasive speech can focus around the poverty problem in the United States.
