What Makes an Oral Presentation Effective

Strategies for Adapting to Particular Audiences

Every audience is different. At the same time, effective speaking is about making certain generalizations and adapting speaking choices to those generalizations. Some suggestions for adapting to particular audience situations are:

The audience feels general agreement with the speaker and embraces the topic
Speakers should devote less time to their introduction.
If the speech is persuasive more attention should be paid to solutions and ways the audience can get involved in pursuing those solutions.
Language can be more emotional as a way of generating enthusiasm.
The audience lacks familiarity with the topic
Speakers should use simple language and strategies that illustrate and clearly explain the topic.
Similarly, the speaker should draw connections between the topic and the audience as a means of generating interest about the topic.
One particular strategy is for the speaker to draw analogies between the topic areas known to be salient to the audience.
The audience disagrees with the speaker and/or topic
The speaker should devote more time to building a positive relationship with the audience.
This likely means a longer introduction that builds to the topic through appeals about which the audience can feel positively.
The speaker will also need to devote more time to building the case for the topic by using evidence likely to be seen by the audience as credible.
The audience lacks an interest in the topic
The speaker should find ways to connect the topic with audience experiences as a means of highlighting its importance to them.
Audiences that lack interest in a topic are also likely to listen less critically, meaning that delivery and appearance may be more important in this type of situation.
