Yesterday I answered an email from a reader who was searching for a little assist with her students Google Slides projects. The students were creating slideshows about birds and desired to add some audio to the slides.
Using Mote wasnt an alternative for her students. So my recommendation was to find or tape-record audio outside of Google Slides then upload it to Google Drive prior to inserting it into the slides. I then created the following video to additional explain my service..

In this new video I demonstrate two options for including audio to Google Slides. The very first choice was to use an audio file that I discovered on Archive.org. The second choice was to use audio that I taped using Vocaroo..
