Preparing an audio recording for Google Slides involves recording a standalone voiceover with an external tool, exporting it in MP3 or WAV format, uploading the file to Google Drive, and then inserting it onto the slide. The Google Slides interface does not offer a standalone option to record independent audio directly onto a slide; therefore, an external recording workflow and Drive sharing permissions form the foundation of the process.
Direct audio recording status and official recording options
Google Slides does not directly include a built-in audio recorder that outputs solely an independent audio file (.mp3 / .wav). According to official documentation, when you want to record narration directly over your slides, the "Slides recording" feature or the Google Vids integration comes into play. These tools record your presentation as a video session with audio or webcam footage. Details are available on the Google Slides Recording Help page. It is important to note that these features may be offered only on specific work or school (Google Workspace) accounts, and the recording process requires Google Chrome or Microsoft Edge browsers.
When recording presentations with the Google Vids integration, you can select "Audio", "Camera & Screen", or "Screen" modes. The options and editing capabilities in this process are detailed in the Presentation Recording with Google Vids guide. However, if your goal is to add an independent voiceover object that plays when a specific slide opens or when clicked—rather than a full presentation session converted into a video—you must record the audio using an external tool and link it to the slide via Google Drive.
Choosing external recording equipment and software
When preparing your slide narration, using an external USB microphone or a quality headset microphone filters ambient noise much better than a device's built-in microphone. For audio recording, you can choose Audacity, OBS Studio (by exporting only audio), or your operating system's built-in sound recorder.
During recording, selecting an echo-free environment, keeping the microphone approximately 15-20 centimeters away from your mouth, and speaking at a slight angle to prevent direct breath from causing plosives will enhance clarity. Free and open-source audio editors such as Audacity help you trim silent moments at the beginning and end of the recording and filter out background noise.
Supported audio formats and export settings
Google Slides' in-slide audio insertion tool supports .mp3 and .wav audio files stored on Google Drive. The MP3 format in particular is the most practical choice for spoken narrations due to its balanced file size and broad compatibility.
When exporting, you can apply the following technical values:
Format: MP3 (.mp3) or WAV (.wav)
Sample Rate: 44.1 kHz or 48 kHz
Bitrate: 128 kbps or 192 kbps (provides sufficient bandwidth for spoken-word voiceovers alone)
Channels: Mono (stereo is not mandatory for spoken dialogue and reduces file size)
When exporting your files, using clear naming based on slide number and topic (for example, slide-02-product-features.mp3) prevents confusion when searching inside Google Drive.
Uploading to Google Drive and configuring access permissions
Google Slides does not play audio files directly from local device storage; every audio file is retrieved via Google Drive. Therefore, uploading the file to Drive after recording is complete is required:
Upload the file to Drive: Open drive.google.com, create a dedicated folder for your presentation, and transfer your audio files here.
Check sharing permissions: Right-click on the audio file and open the "Share" menu.
Configure general access: If you intend to share your presentation with people outside your organization or anyone with the link, set general access to "Anyone with the link - Viewer". Otherwise, users with whom you share the presentation will encounter an access restriction when attempting to listen, even if they can see the audio icon on the slide.
To avoid authorization issues in sharing configurations, you can review the verification steps in our guide on audio not playing in shared Google Slides.
Inserting audio onto a slide and playback controls
Once your audio file is uploaded to Google Drive and sharing permissions are confirmed, adding it to the presentation is completed through these steps:
Open your Google Slides file and click on the slide where the audio will reside.
From the top toolbar, go to "Insert > Audio".
In the selection window that appears, locate and select the relevant audio file from the "My Drive" or "Recent" tab.
A speaker icon will appear on the slide. With the icon selected, the "Format options" panel opens on the right side. From this panel, you can specify whether the audio starts automatically during the presentation or when the icon is clicked, whether it stops when changing slides, and whether it loops. To manage situations that may arise from browser policies regarding automatic playback, you can consult our article on Google Slides audio not playing automatically. If you want to simplify the interface during your presentation, you can follow the steps for editing the Google Slides audio icon.
Worked example: audio preparation for a 3-slide training module
Below is an example narration plan prepared for a hypothetical internal orientation module (durations and titles are illustrative):
Slide 1 (Introduction): File name orientation-s01-welcome.mp3 (Illustrative duration: 18 seconds). Script: "Welcome to our internal training portal. In this module, we will explore the foundational steps of information security."
Slide 2 (Security Principles): File name orientation-s02-security.mp3 (Illustrative duration: 32 seconds). Script: "To activate two-step verification, navigate to the account security tab from your profile settings."
Slide 3 (Conclusion): File name orientation-s03-completion.mp3 (Illustrative duration: 12 seconds). Script: "Congratulations, you have completed the basic security module. Please complete the brief evaluation survey."
These audio clips were recorded and exported in sequence, uploaded to the designated folder on Google Drive, and playback controls were configured on each slide using the format options panel.
Common issues and troubleshooting
Audio does not play on the slide or file cannot be found: The original audio file in Drive may have been deleted, moved to the trash, or relocated. Verify that the file remains accessible on Drive.
Audience members receive an authorization error: Sharing the presentation file does not automatically share the audio file. Check the Drive sharing settings of the audio file to ensure that "Anyone with the link - Viewer" is active.
Recording volume is too low: Apply a normalize filter in your recording software to bring the peak level to around -1 dB and re-export.
Pre-publish checklist
Audio was recorded externally, and unnecessary silences and background noises were removed.
File was exported in MP3 or WAV format.
Audio file was uploaded to Google Drive.
Drive file sharing permission was verified as "Anyone with the link - Viewer".
File was inserted onto the slide via "Insert > Audio" and a test listen was conducted.
The link was opened in an incognito window to confirm that the audio plays smoothly from the perspective of an unauthorized user.
Can I upload audio in MP4 format into Google Slides?
The "Insert > Audio" menu in Google Slides only lists MP3 and WAV audio files stored on Google Drive. You cannot add an MP4 file directly as audio; you can insert the video using the "Insert > Video" menu, or convert the audio track of the video file into MP3/WAV format using an external converter and insert it onto the slide as audio.
If I delete the audio file from Google Drive, will the audio in the presentation continue to work?
No. Google Slides does not store the audio file embedded inside the presentation; it links to the source on Google Drive. If the file in Drive is deleted, moved to the trash, or has its access revoked, the player on the slide will not find the file and will return an error.
