To identify the intended audience of a speech, the best way is to:
1. **Analyze who may relate to the argument**: Look at the content of the speech, the topic being discussed, and the arguments presented. This will help in understanding which group of people or demographic the speech is tailored towards. For example, if the speech is about student loan debt, the intended audience is likely students, recent graduates, and parents.
2. **Ask the audience a lot of general questions**: Engaging with the audience and asking questions can provide valuable insights into their interests, knowledge level, and concerns. By asking questions related to the topic of the speech, you can gauge the audience's familiarity with the subject matter and tailor the speech accordingly.
Analyzing the speech content and engaging with the audience through questions are effective ways to identify the intended audience and ensure that the speech resonates with them. Counting the number of people in attendance or evaluating the factual accuracy of the speech may not directly help in determining the intended audience.
