In PowerPoint documents, speaker notes can help people store the information they want to mention. During the presentation, speaker notes allow people to view the notes on their personal screen while other audience can only see the slides. This article will introduce how to add, read and delete speaker notes in a PowerPoint document using Free Spire.Presentation for Java.
