Academic guest speakers tend to be very smart and have a lot of information in their head;trying to get it out of their mouth in the form of a speech can prove difficult.
As a motivational speaker at healthcare conferences I see a lot of academic guest speakers with really great content that is disorganized and their delivery is disastrous.
When presenting lots of content, layer your key points in a logical progression and add meaningful analogies to make the content come alive.
Have a clear goal,
Present only the most relevant content to the audience. They don't need to or want to know everything you know about your speech topic. Suss out only the most relevant information and present that.
A good speech has an ebb and flow. Load in content, than give the audience time to digest the information with speech interaction. Throw in some analogies and stories, load in more content.
Keep the audience in mind when developing your message. Gear your speech to the group. What level are they ( beginner, intermediate, advanced)? Be careful not to speak over there head or at a level too elementary for them.
End strong with a clear call to action. What do you want people to do after your speech? Answer this question in the beginning and it will give a clear direction for your speech to guide the audience in the direction of your call to action.
An academic Guest speaker can be a motivational speaker if you consider the human element of your message. Where is the inspiration and motivation and how can you highlight it in your talk?
