You can record your slide show to capture narration and slide timings at the same time. Or, you can record your slide show to archive a meeting, so that presenters or absent team members can review the presentation later and hear any comments made during the presentation.
To do this procedure, your computer must be equipped with a sound card, microphone, and speakers. Make sure that you aren't running any other sound recording applications, such as Speech Recognition.
Recording slide timings will also record the timing and duration of animation effects and the use of any triggers on your slide. You can turn the timings off when you don't want the presentation to use them.
Narration is not saved when you save a presentation as a movie.
Do any of the following:
Record a presentation
Change the narration on a slide
Set slide timings manually
Turn off narration or slide timings before you play a slide show
