Audio Overview Intermediate

One of NotebookLM's most distinctive features is Audio Overview - the ability to generate a podcast-style audio discussion between two AI hosts who conversationally explain and discuss your source material. It is like having a custom podcast created from your documents.

What is Audio Overview?

Audio Overview generates a natural-sounding conversation between two AI hosts who discuss the content of your uploaded sources. The hosts explain concepts, ask each other questions, share insights, and make the material accessible in an engaging audio format.

Why Audio Overview Matters: Audio learning is powerful for retention and accessibility. Commuting, exercising, or doing chores? Play the Audio Overview of your study materials. It transforms dense documents into an engaging listening experience.

Generating an Audio Overview

  1. Prepare your sources

    Make sure you have at least one source uploaded to your notebook. Select the sources you want included in the audio discussion.

  2. Click "Generate" in the Audio Overview section

    In the notebook, find the Audio Overview panel (usually in the top section or Studio panel). Click the "Generate" button.

  3. Optionally add custom instructions

    Before generating, you can provide instructions to customize the audio. For example, "Focus on chapter 3" or "Explain concepts as if speaking to a beginner."

  4. Wait for generation

    Audio Overview generation takes a few minutes. The length depends on the amount of source material, typically producing 5-15 minutes of audio.

  5. Listen and download

    Play the audio directly in NotebookLM or download it as an audio file to listen offline.

Customizing Your Audio

You can guide the Audio Overview generation with custom instructions:

Instruction Type Example Effect
Focus area "Focus on the methodology section" Hosts spend more time discussing the specified topic
Audience level "Explain for a high school student" Simpler language, more analogies, less jargon
Specific questions "Address the limitations of the study" Hosts discuss the specific topic you requested
Tone "Keep it light and conversational" More casual discussion style
Comparison "Compare the views in Source 1 and Source 2" Hosts contrast and compare multiple sources

Best Use Cases

Study Aid

Upload your textbook chapters and generate audio to listen while commuting or exercising. Great for exam preparation.

Research Digest

Upload several research papers and get an audio summary of the key findings, methodology, and implications.

Meeting Prep

Upload meeting documents, proposals, or reports and listen to a discussion that highlights the key points before the meeting.

Content Creation

Use the AI-generated discussion as inspiration for your own podcast, blog post, or presentation.

Limitations

Things to Keep in Mind:
  • Audio Overview is generated by AI and may occasionally simplify or miss nuances in your source material
  • Generation takes a few minutes and cannot be interrupted once started
  • The audio is in English only (as of the current version)
  • You cannot edit the generated audio - if you want changes, regenerate with different instructions
  • Very short sources may produce less engaging audio discussions

Try It Yourself

Upload a research paper or article to a notebook and generate an Audio Overview. Try adding custom instructions like "Focus on the conclusions and explain them simply." Listen to the result and compare it to reading the original source.
