In Keynote ’08, you can take advantage of the new Narration feature to record a voiceover on every slide. Since Keynote saves your timing, the narration will pause as you move from one slide to the next.
- Connect an external microphone to your Mac or use the built-in microphone (if available).
- Go to the slide from which you want to begin recording. (When you create a recorded slideshow, playback begins with the slide from which you started recording.)
- Choose Record Slideshow from the File menu. Keynote plays your presentation full screen.
- Speak into the microphone to record your narration. The pulsing red light in the upper-left corner lets you know you’re recording.
