To add a recording to go with a slide in Google Slides, you will actually be recording a video and inserting it on that slide.  It will be easier to create a separate video for each slide so that it will autoplay when people play your slides.  The slides will have to be in Presentation Mode for this to work when the person views it.  

Creating your videos

To record your voice for each slide, you will be recording a screencast of your slide and then uploading that video to your Google Drive.

  1. Have your slide open and on the screen.  You can use either Quicktime or Screencastify (a Chrome extension) to record your screen.  If your microphone is not working, restart your computer as the driver for the microphone has been known to crash if your computer has not been restarted in a while.
  1. Using Quicktime
  1. Open Quicktime - found in your applications “Other” folder.
  2. File - New Screen Recording

  1. Click record and record your audio for that slide.  When you are done, click the stop button in the top row of your screen.
  2. Save your file (File - Save) and then upload to your Google Drive.  
  3. You will need to change the viewing permissions on your video file so others will be able to see it.  Right click on your file in your Drive and select Sharing.  Make it so anyone with the link can view.

You can also create videos directly in your Drive using an app, directions can be found at 

Adding Videos to Google Slides

You should have a video for each slide in your slide deck.  You will be inserting the video onto the slide and making it so that the video will autoplay when the slide starts.

  1. While on the slide where the video will play, select Insert - Video.

  1. After it is inserted onto the slide, you will want to resize the video and place it in a corner.  Then right-click the video and select “Video Options”.

Continue this for each slide, making sure to change the viewing permissions for each video so that anyone with the link can view.

Bonus tip: Change the sharing URL so it starts in presentation mode.

When you get the URL to share your presentation with others, the URL will automatically take them to where they are viewing your presentation but it is not in presentation mode.

And that URL can look like

Delete the end of that URL until the slash before edit and add the word: present 

Now when people click on that link, it will open up into presentation mode and look a lot better.
