excitedly shared the Google Slides Add-on called AudioPlayer for Google Slides. The video tutorial that I made for about it has proven to be popular too. Recently, I've received comments from viewers of that video who said that they can't find the Add-on. It turns out that the developer of the Add-on has turned it into a Chrome extension.
AudioPlayer for Slides is a Chrome extension that will let you add music or spoken audio to your Google Slides presentations. With the extension installed you can simply right-click on a slide in your presentation and then select an audio file from your Google Drive to play on that slide. Unfortunately, the audio file will only play on the selected slide and not over all of the slides throughout the presentation. It should also be noted that you can only play audio files that you have stored in your Google Drive.
Applications for Education
AudioPlayer for Slides could be useful to students who would like to add a little bit of background music to presentations. Students could also use this extension to add spoken audio to their slides. They will have to record the spoken audio in a separate tool (Vocaroo is easy to use for that purpose) and then add the audio recording to their slides.
It's important to note that your students will need to have audio files stored in their Google Drive accounts before using AudioPlayer for Slides.
