Generate an Audio Overview in NotebookLM

Audio Overviews are comprehensive analyses of the main topics in your uploaded documents, presented by AI. Their purpose is to offer detailed summaries and faithfully reflect the original content, avoiding the incorporation of subjective opinions from the AI presenters.

Generate an Audio Overview

To generate or delete an Audio Overview, edit permission for the notebook is required.

• Open an existing notebook or create a new one and upload the necessary sources.
• Go to the “Studio” panel and locate the “Audio Overview” section.
• Under “Detailed Conversation,” you have two options:
  • Generate: To create an audio overview.
  • Customize: To focus the audio on a specific topic. By selecting this option, you can enter a guiding prompt of up to 500 characters to provide instructions on topics to highlight or adjust the level of detail.

Within the panel, you can also select the desired duration for the generated audio:

• Shorter
• Default
• Longer

Important:

Audio overviews, including the voices, are generated by artificial intelligence and may contain inaccuracies or audio glitches. NotebookLM may take a couple of minutes to generate the Audio Overview.

Manage your Audio Overview:

• To modify the playback speed, choose the “More” option
• “Change playback speed.”

Tip: While working in NotebookLM, you also have the option to listen to the Audio Overviews. This functionality allows you to explore relevant quotes, consult sources, and get references, all while the Audio Overview plays in the background.
