Choosing an Informative Speech Topic
Being a successful informative speaker starts with choosing a topic that can engage and educate the audience. Your topic choices may be influenced by the level at which you are speaking. Informative speaking usually happens at one of three levels: formal, vocational, and impromptu.Rudolph Verderber, Formal informative speeches occur when an audience has assembled specifically to hear what you have to say. Being invited to speak to a group during a professional meeting, a civic gathering, or a celebration gala brings with it high expectations. Only people who have accomplished or achieved much are asked to serve as keynote speakers, and they usually speak about these experiences. Many more people deliver informative speeches at the vocational level, as part of their careers. Teachers like me spend many hours lecturing, which is a common form of informative speaking. In addition, human resources professionals give presentations about changes in policy and provide training for new employees, technicians in factories convey machine specifications and safety procedures, and servers describe how a dish is prepared in their restaurant. Last, we all convey information daily in our regular interactions. When we give a freshman directions to a campus building, summarize the latest episode of American Idol for our friend who missed it, or explain a local custom to an international student, we are engaging in impromptu informative speaking.
Whether at the formal, vocational, or impromptu level, informative speeches can emerge from a range of categories, which include objects, people, events, processes, concepts, and issues. An extended speech at the formal level may include subject matter from several of these categories, while a speech at the vocational level may convey detailed information about a process, concept, or issue relevant to a specific career.
Since we don’t have time to research or organize content for impromptu informative speaking, these speeches may provide a less detailed summary of a topic within one of these categories. A broad informative speech topic could be tailored to fit any of these categories. As you draft your specific purpose and thesis statements, think about which category or categories will help you achieve your speech goals, and then use it or them to guide your research. Table 11.1 "Sample Informative Speech Topics by Category" includes an example of how a broad informative subject area like renewable energy can be adapted to each category as well as additional sample topics.
