In yesterday's Practical Ed Tech Live session I answered a question that I seem to be getting asked a lot lately. That question is, "do you know how to add audio to Google Slides." You can add audio to Google Slides if you use YouTube or Google Drive to host videos that contain audio tracks. In the videos below I explain and demonstrate how you can add audio to your Google Slides presentations.
And if you just want to make an audio slideshow that plays on its own, you can use the YouTube Audio Slideshow creator. My video below shows you how to use it.
