Additionally, I have analyzed and published a list of outstanding impromptu speech ideas on different subjects.

What is an Impromptu Speech?

An impromptu speech is a speech type in which you as a speaker must prepare and present your ideas on a certain topic within a limited time. Most impromptu speeches last 5 to 7 minutes and need 1 to 3 minutes of preparation. However, the speech preparation time will vary depending on the event. This type of speech is often given in debate competitions and public speaking classes.

The primary goal of this speech is to assess and improve an individual’s public speaking skills, clarity of thought, and creativity. Impromptu speech, like other long-format speech forms, requires a proper structure to help listeners understand the speech context. Also, it will allow you to think rapidly and talk well with minimal preparation time. Furthermore, giving this speech will help you gain confidence and overcome stage fear.

Impromptu Speech Preparation Tips

When preparing an impromptu speech, you should make sure to use the P.R.E.P [Point, Reason, Example, and Point] method and the Past-Present-Future strategy. These two tactics will help you to effectively structure the speech content.

Impromptu Speech Topics


The P.R.E.P method

  • Point: Explain your core idea.
  • Reason: Provide a rationale for your point.
  • Example: Give an illustration or an example.
  • Point: To emphasize your key point, restate it.

Here, is an example for your better understanding. Assume your impromptu speech topic is “Should Teenagers’ Access to Social Media Be Limited?”

  • Point: I think there should be some restrictions on teens’ use of social media.
  • Reason: According to studies, excessive social media use might spoil mental health.
  • Example: Teens who use social media extensively report greater rates of depression and anxiety.
  • Point: Although social media can be a useful tool, it is essential to establish time restrictions and encourage responsible usage.


  • Examine how the problem has evolved.
  • Analyze the present situation surrounding the subject.
  • Share your ideas or forecasts about how the problem will evolve.

Know How to Choose an Impromptu Speech Topic

Never attempt to give an impromptu speech without proper preparation. Make sure to update your knowledge of popular or trending topics by reading relevant books, magazines, and so on. This will help you to quickly craft your speech content, especially, when you are asked to give an impromptu speech on the latest issues or anything related to your field of study.

For instance, if you are invited to give an impromptu speech on Artificial Intelligence, then this is what you should do.

  • First, think about the subject, and quickly generate potential speech topics. To give an impromptu speech on artificial intelligence, you may consider topics such as the future of AI, the replacement of human jobs by AI, and so on.
  • After listing out the possible impromptu speech ideas, brainstorm and find out what topic has a good discussion scope and what topic contains necessary information, facts, and resources.
  • From the gathered list of impromptu speech prompts, always choose a topic that you are familiar with, knowledgeable about, and interested in discussing.
  • Personal familiarity with a topic is advantageous because you will be able to speak more naturally about it.
  • Give preference to a topic with a limited scope because you will only have 5 minutes to explain it.
  • The objective of an impromptu speech is to enlighten or persuade the target audience. So, pick a topic that meets these criteria.

When speaking spontaneously, it is normal to be concerned about appearing silly. But keep in mind that the goal of impromptu speaking is not perfection. You should be certain enough to showcase your critical thinking abilities, communication skills, and situational flexibility. Furthermore, you should concentrate on communicating yourself clearly. Also, you should not be scared to take a moment to collect your thoughts. When compared to a panicked rambling, a deliberate pause is far preferable.
