How to Add a Voiceover on Google Slides: A Quick Guide5 min read

Adding a voiceover to Google Slides presentations is straightforward if you’ve already created a voiceover, and you’re looking to add the audio file to a slide in your presentation.

If you haven’t created a voiceover, and you’re looking to use Google Slides to record a voiceover, well, Google Slides doesn’t have built-in functionality to record voiceovers.

You can only insert audio files into your presentations on Google Slides. You’ll have to create the voiceover separately and then add it to your presentation on Google Slides.

We’ll first show you how to record or generate a voiceover using free tools online and then give you step-by-step instructions on how to add a voiceover in Google Slides.

You can either record your own voiceover using a voice recording tool or generate a voiceover using text-to-speech software.

Let’s see how you can record a voiceover. We’ll be using Rev’s free online voice recording tool to record your voiceover.

You can also use offline voice recording software such as Apple’s GarageBand or Audacity.

  2. You can now pause the recording by clicking on the Pause button.
  3. You can then resume recording by clicking on the Resume button or preview what you’ve recorded by clicking on the Preview button.

    Clicking on the preview button will take you to a window where you can preview, transcribe, or download the recording. Click on the download icon right next to the transcribe button to download the recording.

If you’d rather generate a voiceover using text-to-speech software, you can use Animaker’s free text-to-speech tool.

Animaker uses the NTTS (Neural Text To Speech) model to generate ultra-realistic, crystal-clear audio narrations!

You can then pick a Gender, Language, or Voice for your voiceover.

Click on the round button in the top left corner of the window to adjust your voiceover’s Speed, Pitch, and Volume.

If you made changes to the speed, pitch, or volume, you can undo these changes by clicking on the Reset button. 

Also, you can add a breath or break effect between each word and adjust how long it should last. Simply click on the dot between any two words to add a Breath or Break between them. 

You can also let AI take care of making your voiceover sound good by using the auto-enhance functionality. This feature automatically adds the breath effect, speed, pitch, volume, etc., based on the text you’ve entered. Tick the Auto enhance checkbox to auto-enhance your voiceovers. 

Step 3: Click the Preview button to play and preview the voiceover.

And then click on the Download button in the top right corner of the window to instantly download your voiceover to your local computer in MP3 format.

One thing to keep in mind is that in order for you to be able to add an audio file to your Google Slides presentations, it must be in MP3 or WAV audio format.
