Actuate speech topics are numerous, but a few examples include why to vote in an election, environmental issues, food choices and social concerns. According to the Merriam-Webster dictionary, to actuate means to cause someone to do something or to act in a certain way, so an actuate speech is a persuasive speech.
When an actuate speech topic is chosen, the speaker needs to consider whether the audience agrees or disagrees with the argument. If the audience has positive feelings about the topic, talking about it is easier, but it may be difficult to supply details that are unknown to the listeners. The other factor to consider is whether the audience cares about the topic — indifferent spectators may be more difficult to persuade one way or another.
