In the corporate world of flexible hours and hybrid working, it can be difficult to find a time when everyone is available to attend a live company presentation or training session. So, to make these resources available to all, why not upload your presentation to your internal resource website so employees can watch and learn at a time that suits them? You could even include an audio commentary to make it more engaging and more informative. If you’re not sure where to start, follow our guide on how to voiceover a PowerPoint or Google Slides presentation.

How to do a voiceover on Google Slides

While Google Slides doesn’t have a built-in tool specifically designed for voiceover, you can still create one in just a few simple steps. All you need is Google Slides and a computer or phone with a microphone.

1- Record an audio file for each slide

Rather than going through the time-consuming process of recording and re-recording Google Slides voiceovers until they’re perfect, why not optimize the process with an AI tool? LOVO AI’s text to speech tool allows you to create audio files in minutes from an existing script, saving you time and resources. 

Once you have all your recordings ready, label each file clearly so you know which audio goes with each slide. 

2- Upload each voiceover file to Google Drive

Make sure you create a new folder exclusively for these recordings so they’re easier to find in the next step.

3- Add the audio to each slide

Import the audio into your Google Slides document. You can import a different audio file for each slide by going to Import > Audio. The files you uploaded should be located in the ‘Recent’ tab, but you can also search for the file manually. 

4- Adjust your settings

Tinker with your audio settings to achieve the desired result for your Google Slides voiceover. Simply click on the speaker icon which will have appeared on your slide in Step 3, then go to Format > Format Options. Some options to choose from include:

  • Autoplay – do you want your audio to play automatically or after a viewer manually clicks?
  • Loop – stop your audio after one play or repeat once it ends.
  • Button size and color – change the way it looks on your slide.

How to voiceover a PowerPoint 

There are two different ways you can voiceover your PowerPoint and take your presentation to a new level. 

Option 1: Record a voiceover in PowerPoint

The software has several hidden features that the average user doesn’t know about, including the ability to add voiceovers. All you need is Microsoft PowerPoint and either a computer with a microphone, an external plug-in microphone, or earphones with a built-in mic. 

Step 1 – In the top menu, go to Slide Show > Record Slide Show. You’ll have the option to record from the beginning of the presentation or from the slide you’re currently on.

Step 2 – Start recording. Once you choose your start point, you’ll be taken to the full-screen recording page with options to record, stop, and replay. Hit record and there will be a countdown timer from three. 

FYI, anything you type in the notes section of the PowerPoint can be viewed in recording mode by clicking on the ‘Notes’ button at the top. The recording will stop automatically when you reach the final slide. 

Step 3 – Listen back to your PowerPoint voiceover and check that everything’s okay. Just hover over the speaker icon in the corner of your slide to play. Head back to the recording page to fix any errors. 

Option 2: Upload a media file

Instead of recording straight into the PowerPoint software, you can upload your own audio files into each slide. This is perfect if you don’t have the time to record your own voiceover, or simply don’t want your voice attached to the project. LOVO AI’s text to speech tool allows you to create realistic, human-like voice recordings in minutes, which can easily be integrated into your PowerPoint presentation. 

Once you have your voiceover files, go to PowerPoint and click Insert > Audio > Audio from file. Choose your preferred setting: loop, autoplay, or play across slides.

You have two options here: 

  • Create one audio file per slide, which you can add to each slide individually. Set them to play automatically once you advance to the slide that the audio file is on.
  • Create one single audio file for the whole presentation, and have it play across all slides.

Once the voiceover is added, you’ll see a small sound icon on your slide. You can use the picture format buttons on the Audio Format tab to add a frame, border, or other effects to the audio icon.
