Organize logically:

Choose the right organization for your speech which may change depending on the topic

Use simple language:

Avoid information overload:

Narrow your topic down so it will fit in the time allowed


Make your speech memorable

Build Repetition

3 ways to incorporate:

  • restating your main points in your introduction, body and conclusion

  • where a word or a phrase is repeated in a poetic way, either throughout the speech or at a critical point in the speech

Ex.  ain’t I a women speech

  • through nonverbal communication such as holding up 4 fingers when you say 4

Appeal to different ways of learning

You need to teach with all learning styles in mind not just yours

Audiences retain information better of what they can hear and see or when they can actively do something

You can also use association like explaining rugby using football rules or acronyms to help people remember information
