A Speaker's Voice Contains Many Tools Than Can Be Used During A Speech

When you find yourself giving a speech, you quickly realize that what you are missing is any sort of tools with which to give the speech. If you were a painter, you’d have a canvas, brushes, paints, thinners, etc. with which to make your creation. However, when you are giving a speech it’s just you and your audience. Make you feel sorta naked, doesn’t it?

It turns out that you actually do have a toolbox with which to create your speech – the words that you’ll be using. It turns out that not only the words that you choose to use, but the way in which you speak these words can cause a powerful reaction in your audience. Debra Johanyak is a professor of English at the University of Akron and she has come up with a list of different ways that we can use our voice to make our point during a speech.

Let’s take a look at the different verbal delivery “tools” that Dr. Johanyak has come up with:

• Words That You Accent: It turns out that not all words are created equal – you have the ability to emphasize certain words. As an example, consider the sentence “After cutting the green wire, a sudden silence descended over the entire bomb squad.” Simply by pronouncing the word “green” differently, you can draw your audience’s attention to it.
• Slow Pitch Speaking: The pitch of your voice controls how high and how low your voice goes. This is a powerful way to communicate emotion during your speech: “Once I saw that the cage was empty, I knew that the 6′ snake could be anywhere in the house.” The word “anywhere” can be said in a higher pitch than the other words in order to draw attention to it.
• Just Be Quiet: The most powerful speaking tool is also the simplest – just be quiet. When we add periods of silence to our speeches, it adds emphasis to the words that came before and sets the stage for the words that are to come next.

There you have it – now your speaking toolbox is actually looking rather full!

When you give a speech do you use your voice to its fullest? Have you ever ever accented words or varied your pitch to make a point? Are you able to remember to use quiet pauses to make a point? Leave me a comment and let me know what you are thinking.

Presenters Who Can Visualize Lots Of Data Are Better Communicators

We would all like our next presentation to be our best. However, when we’ve got lots and lots of data to present, we can all too easily overwhelm our audience. What’s a presenter to do? It turns out that the good folks over at IBM have come up with a way to help us out of this mess that we’ve gotten ourselves into…

Not having enough data to support our position is rarely the issue. Rather, having too much data and not enough knowledge that has been created by processing that data IS the issue. Researchers at IBM have set up an experimental web site at www.many-eyes.com where you can upload data and then play around with it in order to visualize it.

Now I’m sure that everyone is well aware of the graphing capabilities of both PowerPoint and Excel. The problem is that EVERYONE is aware of these and so all too often, every presentation starts to look the same.

The scientists at IBM’s Watson Research Center (located up in Cambridge, Mass.) have created this site not so much to help presenters, but rather to help people publish and discuss graphics in a group. However, there is no reason that we can’t make use of the tools that they are providing us with and if we can get some social networking suggestions along the way, all the better.

The web site is the creation of two IBM researchers, Martin Wattenberg and Fernanda Viegas. What they wanted to do was to take the sophisticated data visualization tools that have been available to researchers and make them available to the masses.

Currently, the Many Eyes site provides 16 different ways to present your data. Yes, your old friends the stack graphs and bar charts are there. However there are also more interesting presentations such as diagrams that let people map relationships and TreeMaps which show information in colored rectangles.

This Is An Example Of A TreeMap Visualization

When the site first became available, they only offered visualisation tools that would work with numbers. Quickly the site owners discovered that their users were attempting to upload books and blog posts. Based on this discovery, they went ahead and added visualization techniques that would work with unstructured text.

One of my favorite unstructured tools is the Tag cloud that you’ve probably been seeing show up on blogs (like mine). The more a word is used, the larger it appears in a tag cloud. Here’s an example:

Example of a Tag Cloud Visualization

If you want to learn how to use this tool to process your data, Rich Hoeg has created the Northstar Nerd Tutorial: Data Visualization via IBM’s Many Eyes.

One important point to realize, the tool was really designed to allow people to share data and visualizations. Don’t upload confidential info! You can delete your information after you are done processing it; however, if it has been commented on by others this won’t make the site’s owners very happy.

Have fun coming up with different ways to look at your data and present it to your audience. However, keep in mind that once you start to look at the data in a different way, it may end up giving you answers to questions that you didn’t even know that you had.

When you have to present data as part of a presentation, what format do you normally use? What tools do you use to create your visualizations? Do you think that your audience can understand what your visualizations are saying? Do you feel that all graphs are starting to look the same? Leave me a comment and let me know what you are thinking.
