If you’re tired of saying the same old thing every time you present your slide show, why not record your talk so that your presence isn’t required for the presentation? When you record a narration, you’re also setting the length of time each slide is displayed.
Click the Record Narration button on the Slide Show tab to display the Record Narration dialog box.
If you haven’t previously set up a narration on this computer, click each button in the dialog box, and make your recording settings; or, if you have recorded a narration on this computer, change any existing settings if you want to, and then click OK.
When the slide show starts automatically, record your narration as you go through the slides. Continue recording your narration until you’ve completed the slide show.
When PowerPoint asks you whether you want to save the timings for the slide show, click Save to save the length of time each slide was displayed, or click Don’t Save to keep the narration but not the timing used to automatically advance the slides. (To run the presentation with the narration but without the slides automatically advancing on the Slide Show tab, clear the Use Rehearsed Timings check box.)
Run the slide show to make sure it’s being presented exactly the way you want.
