The three ways to add audio to Google Slides

Google Slides lets you add sound in three ways: upload an audio file from your computer, insert a YouTube video with sound, or record yourself speaking directly into the slide. The method you pick depends on what you already have and how much time you want to spend preparing.

Uploading a file works best if you have an MP3, WAV, or OGG file ready to go. Recording directly in Slides saves time if you're adding quick narration or instructions. YouTube videos are useful when you want to embed a clip that's already online — a music sample, a news segment, or a tutorial — without downloading it first.

All three methods let you play the audio during your presentation, and you can set it to play automatically when you reach that slide or wait for you to click. The audio stays attached to the slide, so it travels with your presentation if you share the file or present on a different computer.

Key Takeaways

  • Upload audio files (MP3, WAV, OGG) directly to a slide using the Insert menu, and the file size must stay under 100 MB.
  • Record audio straight into Google Slides without leaving the app, which is fastest for adding your own voice or quick narration.
  • Embed YouTube videos to include audio that's already online, though you need the video's URL and an internet connection to play it during your presentation.
  • Set audio to play automatically when the slide appears or require a click to start, and adjust the volume before you present.
  • Audio files you upload are stored with your presentation, but embedded YouTube videos need internet access to play during your talk.

Uploading an audio file from your computer

Open your presentation in Google Slides and go to the slide where you want the audio. Click Insert in the menu bar, then scroll down and click Audio. A window opens asking you to choose a file from your computer. Find your MP3, WAV, or OGG file and click Open. Google Slides uploads the file and places a small speaker icon on your slide.

The file size limit is 100 MB, which covers most audio files you'll encounter. If your file is larger, you can compress it using free tools like Audacity (available for Windows, Mac, and Linux) before uploading. Once the audio is on the slide, click the speaker icon to see playback options. You can set it to play automatically when the slide appears, or leave it set to play only when clicked during your presentation.

The audio stays embedded in your presentation file, so it will play even if you open the file offline or on a different computer. This makes uploaded audio reliable for presentations where you can't count on internet access.

Recording audio directly in Google Slides

If you want to add your own voice without uploading a file, use the built-in recording tool. Click Insert, then Audio, and instead of choosing a file, click Record audio at the bottom of the window. A recording panel opens with a red record button. Click it to start, speak into your computer's microphone, and click the stop button when you're done.

You can listen to what you recorded before saving it. If you're happy with it, click Save and the audio attaches to your slide. If you want to try again, click the trash icon and record a new take. This method is fastest for adding quick instructions, speaker notes, or narration without leaving Google Slides.

The recording quality depends on your microphone. A built-in laptop microphone works, but a USB headset or external microphone will sound clearer. Keep recordings short — 30 seconds to a few minutes — because longer audio files can slow down your presentation file.

Embedding audio from YouTube

You can embed a YouTube video that contains audio you want to use — a song, a speech, a sound effect, or a tutorial. Click Insert, then Video, and paste the YouTube URL into the search box. Find the video you want and click it. Google Slides embeds the video player on your slide, and the audio plays when you click the play button during your presentation.

This method works well when the audio you need is already on YouTube and you don't want to read and upload a separate file. The downside is that your presentation needs an internet connection to play the video during your talk. If you're presenting in a location with unreliable WiFi, this method can fail at the moment you need it.

You can resize the video player by dragging its corners, and you can set it to autoplay when the slide appears, though autoplay is usually distracting. Most presenters leave it set to play on click so they control when the audio starts.

Controlling when audio plays and adjusting volume

After you add audio to a slide, click the speaker icon (for uploaded or recorded audio) or the video player (for YouTube audio) to see options. You'll find a toggle for Autoplay — turn it on if you want the audio to start automatically when you reach that slide, or leave it off if you want to click to start it. You can also adjust the volume slider to make the audio quieter or louder.

Test the volume before you present. What sounds right in your quiet office might be too quiet in a large room or too loud in a small one. If you're presenting to a group, ask someone to sit in the back and tell you if they can hear it clearly.

If you have multiple audio files on the same slide, they will all play at once if you set them to autoplay, which usually sounds like a mess. Use autoplay for only one audio element per slide, and set the others to play on click so you can control the order.

Troubleshooting audio that won't play

If your audio doesn't play during a presentation, the most common cause is an internet connection problem — especially if you're using YouTube videos. Embedded videos need internet to stream, so if your WiFi drops, the video won't play. Uploaded audio files don't need internet, so they're more reliable for presentations in locations with spotty connectivity.

If an uploaded file won't play, check that the file format is MP3, WAV, or OGG. Google Slides doesn't support M4A, FLAC, or other formats. If you have a file in an unsupported format, convert it using a free tool like Audacity or an online converter before uploading.

If you're presenting in full-screen mode and the audio doesn't play, make sure your computer's volume is turned up and not muted. Some presentation remotes have a mute button that can silence audio by accident. Also check that the speaker icon or video player is actually on the slide — sometimes it gets placed off-screen if you move it around.

File size and storage limits

Google Slides presentations stored in Google Drive have a 5 GB file size limit per file. Audio files take up space, so if you're adding multiple long recordings or high-quality audio, you can hit that limit. A typical MP3 song is 5 to 10 MB, and a 10-minute voice recording is usually 10 to 20 MB, so you have room for quite a bit before you run into trouble.

If your presentation is getting close to the limit, you have two options: delete audio you don't need, or split your presentation into two files. You can also compress audio files before uploading to save space. Audacity lets you export audio at lower bitrates, which reduces file size without making the audio sound noticeably worse.

YouTube videos don't count toward your file size limit because they stream from YouTube's servers, not from your Google Drive. This is another reason to use YouTube embedding if you have a lot of audio content.

Frequently Asked Questions

Can I add audio to just one slide or does it have to be on every slide?

Audio goes on individual slides, so you can add it to one slide, some slides, or all of them. Each slide is independent, so you control exactly where audio appears in your presentation.

What happens to audio if I share my presentation with someone else?

Uploaded and recorded audio travels with the file, so the other person will hear it when they open or present your slides. YouTube videos will play for them too, as long as they have internet access and the video hasn't been deleted from YouTube.

Can I edit or delete audio after I add it to a slide?

Yes. Click the speaker icon or video player and you'll see options to delete it. To replace it, delete the old audio and insert a new file. You can't edit the audio itself inside Google Slides — if you need to trim or change a recording, do that in Audacity or another audio editor before uploading.

Does audio play if I read my presentation as a PowerPoint file?

Uploaded and recorded audio will read with the file and play in PowerPoint. YouTube videos won't transfer — they'll appear as a broken link in PowerPoint, so read the YouTube video separately and upload it as a file if you need it in PowerPoint.

Can I add audio to the speaker notes instead of the slide itself?

No, Google Slides doesn't support audio in speaker notes. Audio has to be attached to a slide. If you want to add notes for yourself, type them in the notes section below the slide, but any audio must go on the slide itself.
