  • 55. Text and slides • • • • • www.tudorgirba.com The more text there is on a slide, the more I will tend to speak it as it is written on the slide. But, you can read a text much faster than I can speak it. In such situations, my speech becomes noise as you rather prefer to just go ahead and read it by yourself. That is the reason why slides should not have text that competes with my speech, but rather be as visual as possible to complement it. If I would read this to you, you would likely be reading this line while I would still be somewhere in the middle of the text. © Tudor Girba Zurich - April 23, 2013 91

The result is lots of bullet points and lots of text. However, lots of text competes with the spoken words because we can just read faster than we speak. And we want the audience to hear what we have to say. notes will set you free Another option is to put the text in the notes and provide slides with notes for as printouts.
