      Why use a voice-over on your PowerPoint presentation?

      PowerPoint presentations are a powerful tool for delivering information to your audience. However, multiple slides containing only visual information can be dull. Adding a voice-over to your slides can make the presentation more engaging and easier to follow. An engaged audience is an audience that’s more likely to remember the information you present.

      How to do a voice-over on PowerPoint for free in 4 steps

      Step 1: Write a script

      It’s helpful to write a script before you begin recording. The script will help you to stay on track, stick to timings, make sure that you cover all the essential points and avoid repeating yourself. The script should be concise and straightforward, using simple language that’s easy to understand.

      It’s important to rehearse your script, speaking out loud. This is a good way of identifying any parts that don’t sound right. It also enables you to time yourself, and adjust your script if necessary, to keep to specified timings.

      Remember, don’t just repeat what’s on your slides. Your voice-over adds value by providing extra information. For example, your slides might display bullet points and your voice-over can add further detail for each point. Find out more about writing voice-over scripts.

      Step 2: Record your voice-over

      To record your voice-over, you can use a built-in microphone on your computer, a smartphone or an external microphone.

      Choose a quiet place without any background noise to make your recording. Speak clearly and slowly, maintaining a consistent pace. You can record directly from PowerPoint or you can use free software, such as Audacity or GarageBand (Mac only) to record and then edit your audio. Editing can be used post-production to add different qualities to your voice, such as a richer tone or a slight echo.

      Step 3: Add the voice-over to your PowerPoint presentation

      If you’ve recorded your voice-over outside of PowerPoint, when the recording and any necessary editing are finished you can add it to your PowerPoint presentation. Here's how:

      1. Open your presentation and go to the slide where you want to add the voice-over
      2. Click on the ‘Insert’ tab and select ‘Audio’
      3. Choose the audio file you want to add and click ‘OK’
      4. To set the audio to play automatically, go to the ‘Playback’ tab and select ‘Play in Background’ under ‘Audio Options’.

      Step 4: Sync the audio with the slides

      To ensure that your voice-over timings are right in the final presentation, you might need to sync the audio with the slides. Here's how:

      1. Click on the ‘Transitions’ tab
      2. In the ‘Timing’ group, check the box next to ‘After’ and set the duration for the slide to play
      3. In the ‘Sound’ dropdown, select the audio file you added to the slide
      4. Repeat this process for each slide in your presentation.

      How to do a voice-over on PowerPoint with a different voice

      If you don’t want to use your own voice for your audio recording, you could ask someone else to read your script. However, sometimes that isn’t possible. If you need a voice-over audio and want a different voice, PowerPoint has a solution.

      You can use PowerPoint’s built-in Text-to-Speech (TTS) feature to create a voiceover that is generated by the software. Simply select the text on each slide, go to the ‘Review’ tab, then select ‘Read Aloud’. You can also adjust the speed and language of the TTS voice in the settings.
