It’s not that hard, but I do suggest that you get a decent microphone for recording instead of using a build in mic on a laptop so it doesn’t sound all muddy. Also, to make it sound and flow better, write out a script and go through it a number of times so that you don’t have that weird “1st time caller” voice. Other than that just select the slide that you want to narrate, go to the insert tab, and choose Record Audio on the drop-down menu under the Audio button. Then just click Record, say your say, and click OK when you are done. Make sure that you check the box for “Play Narrations” in the Slide Show tab.
