To record and hear a sound or comment, you need a sound card, microphone, and speakers.
A sound icon appears on the slide.
Tip
If you don't want the sound icon to be visible, in normal view, drag it off the slide. If you didn't set it up to run automatically, do so: Right-click it, and on the shortcut menu, click Custom Animation. In the task pane, under Modify: Appear, in the Start box, click the arrow, and then click Start with Previous.
