The other day I responded to an email from a reader who was looking for a little aid with her students Google Slides jobs. The trainees were producing slideshows about birds and wished to add some audio to the slides.
Using Mote wasnt an option for her trainees. My recommendation was to discover or tape-record audio outside of Google Slides then upload it to Google Drive prior to placing it into the slides. I then created the following video to more discuss my solution..

In this new video I show two choices for adding audio to Google Slides. The first option was to use an audio file that I found on Archive.org. The 2nd choice was to use audio that I recorded utilizing Vocaroo..
