You can add audio to slides that do not have audio by recording audio. Alternatively, you can replace the existing audio in slides by recording audio.
Notes:
To record audio
If the slide already has audio associated with it or if it is a movie slide, a message displays that all existing audio in the slide will be replaced. Click Yes. To stop this message from displaying again, select the Do not show this message again check box.
Note: The Record button is disabled if a slide is open for Advanced Edit. If you navigate to a slide that is open for Advanced Edit while the Recording Audio toolbar is open and the Record Audio button has already been selected, all buttons in the Recording Audio toolbar will be disabled.
The Record button is enabled when Word, Excel, or PowerPoint slides are open for simple edits. If you click the Record button while doing a simple edit and there are unsaved changes, a message is displayed asking whether to save the changes. Click Yes to save the document and proceed. Click No to discard any unsaved changes and proceed. The same is applied for all slides edited with the slide preview (i.e. Word/Excel/PowerPoint).
After the recording, if Auto Advance is enabled for the slide, the slide duration is updated with the new duration at the end of the recording.
The recorded audio will be imported into the selected image or movie slide. The icon will be displayed at the right hand bottom corner of the slide.
