Google Slides lets you record your voice directly into a presentation, and the audio plays back when someone views the slide

You can add narration to individual slides, to a whole presentation, or to specific objects within a slide. The recording tool is built into Google Slides — you do not need to download anything or use a separate app. Once you record, the audio file stays attached to that slide, and anyone who opens the presentation can play it back.

The process takes a few minutes per slide, and you can re-record as many times as you want before you save. If you make a mistake mid-sentence, you can delete that recording and start over without affecting the rest of your presentation.

Key Takeaways

  • Open the slide you want to narrate, click the Insert menu, select Audio, then choose "Record audio" to start recording your voice.
  • Google Slides records directly from your computer's microphone, so test your audio levels before you begin narrating a full presentation.
  • You can record narration for the whole slide or attach audio to a single object like an image or text box.
  • Recorded audio stays in your presentation file and plays back when someone clicks the audio icon or when you set it to autoplay during a slideshow.
  • If you need to edit or delete a recording, right-click the audio icon and choose the option to remove it, then record again.

Recording audio for a single slide

Click on the slide where you want to add narration. Go to the Insert menu at the top, then select Audio. A small window will open with three options: "Record audio", "Upload audio", or "Search the web". Click "Record audio".

A recording dialog will appear. Click the red record button to start, and speak into your microphone. You will see a timer counting up as you record. When you finish, click the stop button (the square icon). Google Slides will save the recording and place an audio icon on your slide. You can drag this icon to any position on the slide, or resize it if you want it smaller or larger.

If you want to listen to what you recorded before saving, click the play button on the audio icon. If you do not like the recording, right-click the audio icon, select "Delete", and record again. You can re-record as many times as you need.

Recording narration for multiple slides in sequence

If you are narrating a whole presentation, you can record one slide at a time and move through them in order. This method works better than trying to record everything in one take, because you can pause between slides and re-record any slide that does not sound right.

Start with slide 1. Record your narration using the steps above. When you finish that slide, move to slide 2 by clicking the next arrow or pressing the right arrow key on your keyboard. Insert audio on slide 2 and record. Repeat for each slide in your presentation.

This approach also lets you check your pacing — you can see how long each narration takes and adjust future recordings if some slides feel rushed or slow. If you realize slide 5 needs a re-do after you have already moved to slide 8, you can go back to slide 5 at any time and delete the old recording, then record a new one.

Attaching audio to a specific object instead of the whole slide

Sometimes you want narration to play only when someone clicks a particular image, text box, or shape — not when they first land on the slide. You can attach audio directly to an object.

Click on the object (an image, shape, or text box) that you want to attach audio to. Then go to Insert > Audio > Record audio. The recording will be tied to that object instead of floating freely on the slide. When someone views the presentation, they will see an audio icon on that object, and the narration plays only when they click it.

This is useful for presentations where you want the viewer to control when they hear each piece of narration, or when you have multiple narrations on one slide and want them to play separately.

Setting audio to play automatically during a slideshow

By default, narration plays only when someone clicks the audio icon. If you want the audio to start playing automatically when a slide appears during a presentation, you can change this setting.

Right-click the audio icon and select "Audio options". A panel will open on the right side of your screen. Look for the checkbox that says "Autoplay when presenting". Check this box, and the audio will begin playing as soon as that slide appears in a slideshow. If you want the slide to advance automatically after the audio finishes, check "Autoplay when presenting" and note the audio duration — you can then set the slide transition to advance after that many seconds.

To set up automatic slide advancement, click the slide itself (not the audio icon), then go to Slide > Slide transition at the top. Set the transition to happen after a specific number of seconds that matches your audio length. Now the slide will advance on its own once the narration finishes.

Checking audio quality and microphone settings

Before you record a full presentation, test your microphone and audio levels. Open any slide and insert a short test recording — just say a few words. Play it back and listen for these issues: background noise, audio that is too quiet or too loud, or microphone problems like crackling or buzzing.

If the audio is too quiet, check your computer's microphone settings. On Windows, right-click the speaker icon in the system tray and select "Open Sound settings", then look for microphone input levels. On Mac, go to System Preferences > Sound > Input and check the input level slider. Speak at normal volume while watching the level meter — it should move into the middle range, not stay at the far left.

If you hear background noise, try recording in a quieter room or closing nearby windows and doors. If your microphone has a mute button, make sure it is not activated. Once your test recording sounds clear, you can proceed with narrating your full presentation.

Downloading or sharing presentations with narration

When you save a presentation with audio in Google Slides, the narration stays in the file. If you download the presentation as a PowerPoint file (.pptx), the audio will download with it and play in PowerPoint as well.

If you share the presentation with others through Google Slides (by clicking Share and entering their email address), they will hear the narration when they open the file. If you share a download link or email the PowerPoint file, the audio goes with it. The only exception is if you convert to a PDF — audio does not transfer to PDF format, so anyone reading a PDF version will not hear the narration.

If you want to share just the audio without the slides, you can right-click the audio icon, select "Download", and save the audio file separately as an MP3.

Frequently Asked Questions

Can I edit my narration after I record it?

Google Slides does not have a built-in audio editor, so you cannot trim or cut parts of a recording. If you want to change something, delete the recording and record again. If you need to edit audio before uploading it, use a free tool like Audacity to trim or adjust it, then upload the finished file to your slide using Insert > Audio > Upload audio.

What if my microphone is not working?

Google Slides will ask for permission to use your microphone the first time you try to record. If you denied permission, go to your browser settings and look for site permissions or microphone settings, then allow Google Slides to access your microphone. Refresh the page and try recording again. If your microphone still does not work, check that it is plugged in and not muted.

Can I record narration on a presentation someone else shared with me?

Only if the owner gave you editing permission. If you can edit the presentation, you can add narration. If you only have viewing permission, you cannot record audio. Ask the owner to give you editor access if you need to add narration.

Does the audio file get stored separately or stay in the presentation?

The audio stays embedded in the presentation file itself. You do not need to manage a separate audio file. When you download or share the presentation, the audio comes with it automatically.

How long can a single narration recording be?

Google Slides does not have a published limit on recording length, but very long recordings (over 10 minutes) may take longer to save. For most presentations, you will record one narration per slide, which is usually under 2 minutes. If you need to record a very long narration, break it into multiple slides or test with a shorter recording first to see how long it takes to save.
