A voiceover narration is a synchronized recording of yourself talking about each slide. To record a voiceover narration, you speak about each slide, advancing through the slideshow at your natural speed. As you advance through each slide or build, your timing is recorded as well and will be preserved when the slideshow is played back for viewers.
To record the voiceover, you can use the computer’s built-in microphone or attach an external one. If you’re using an external microphone, first attach it and use the sound pane of System Preferences to configure the input settings.
Select any slide on which you want the recording to start. If you select a skipped slide, recording starts with the nearest previous unskipped slide.
Do one of the following:
Open the Document inspector, click Audio, and click Record.
Choose File > Record Slideshow.
The slideshow begins to play. A pulsing red light in the upper-left corner of the screen indicates that recording is in progress.
As the presentation plays, speak clearly into the microphone to record your narration.
To advance to the next slide, click the mouse button or press the Right Arrow key.
To pause the recording, click the red recording indicator, or press any of the following keys:
Press any key to resume the recording.
When you’ve finished recording all the slides you want to include in your voiceover narration, press the Escape key to stop slideshow playback and save the recording.
In the Document pane of the Document inspector, notice that the Recorded option appears in the Presentation pop-up menu. A recorded slideshow plays only from the first recorded slide (the one you selected in step 1, above). If you click Play in the toolbar and the presentation doesn’t play as expected, make sure Recorded is chosen from the Presentation pop-up menu in the Document inspector.
To listen to the narration without playing the slideshow, click the Play button on the Audio pane of the Document inspector. Adjust the volume by dragging the Volume slider.
If you change the slides or append new slides to the end of the slideshow, or if you aren’t satisfied with your recording, you can rerecord the slideshow. See Rerecording a Voiceover Narration in a Recorded Slideshow. To learn how to delete the recording entirely, see Deleting a Voiceover Narration from a Recorded Slideshow.
