TRANSFORMING BLOGS INTO PODCASTS WITH GOOGLE'S NOTEBOOKLM
The medium is the message. -- Marshall McLuhan
If you’ve been following along with us, you’ve seen us experimenting with the latest AI products and services, and today’s post is a deep dive into Google’s NotebookLM, a notebook that allows you to ask questions of documents. More interestingly, they recently introduced an AI-generated podcast generated on your materials – it’s really cool! It’s quite realistic sounding, does a great job of summarizing the materials, and, most importantly, gives us another way to interact with our documents. Especially if you enjoy learning through listening, this new feature is right up your alley. We have started featuring these AI-generated podcasts on our last couple of posts and will include one below on this topic (quite meta: an AI-generated podcast on the topic of AI-generated podcasts).
Google’s new feature is called "Audio Overview" and includes AI-generated male and female hosts discussing your documents. This feature allows users to transform written documents, like blog posts and research papers, into dynamic, podcast-style audio. NotebookLM creates natural-sounding conversations that break down complex information into digestible summaries. We'll explore how this cutting-edge tool is reshaping the way bloggers and content creators can turn their written work into engaging audio, unlocking new possibilities for reaching audiences in novel and creative ways. People complain my posts are too long and I certainly don’t want to do an audio recording of each post – can these podcasts be a happy medium for greater exposure and learning?
NOTE: We are continuing our experiment with an AI-generated podcast that summarizes this post by Google’s NotebookLM. Listen here and let us know what you think:
WHAT IS GOOGLE'S NOTEBOOKLM AND AUDIO OVERVIEW?
Google’s NotebookLM is an advanced AI tool designed to help users navigate and comprehend complex information more efficiently. Originally introduced as a research assistant, it allows users to upload documents, from research papers to slides, and generates detailed summaries, study guides, FAQs, and briefings based on the content. Unlike standard search engines, which pull data from the web, NotebookLM focuses specifically on the information you provide, making it a useful tool for those who need insights from their own resources. By summarizing dense materials and highlighting key points, it simplifies the process of understanding and organizing information, offering new ways to interact with your sources, now including YouTube videos.
The latest addition to NotebookLM, the "Audio Overview" feature, takes this functionality even further by turning written documents into audio summaries. The tool generates podcast-like discussions with just one click and couple of minutes, led by two AI hosts that engage in conversational dialogues about the uploaded content. The voices are very believable and surpass the uncanny valley for me. Being a podcast fan, even the banter sounds human (“isn’t that the million-dollar question?” is a common refrain). These AI-generated voices simulate natural speech patterns, complete with pauses, laughter, and interjections, providing a more engaging and accessible way to digest information. This feature provides new possibilities for bloggers like me and other content creators, who can now easily convert our written work into a lively audio format, broadening our audience reach and making content more consumable for listeners on the go.

HOW THE AUDIO OVERVIEW FEATURE WORKS
Using the Audio Overview feature in Google’s NotebookLM is a straightforward process that begins with uploading your documents—whether they are blog posts, notes, slides or now YouTube videos. Once your content is uploaded, you can select the "Audio Overview" option, which triggers the generation of an audio summary. This summary is presented in a conversational format between two AI hosts, making the material more engaging and easier to follow. The AI hosts will discuss the key points of your document, breaking down complex ideas into simpler, digestible conversations.
However, while the feature is powerful, it comes with some limitations. The AI hosts only generate discussions based on the information you upload, without pulling from broader internet data as necessary. Thus, the quality and accuracy of the audio summary are entirely dependent on the provided sources, but you can be sure the discussion is limited to your documents. Once in a while there can be occasional errors in tone, phrasing, or pronunciation that arise, but they are very few and far between in my experience so far. Despite these minor shortcomings, the Audio Overview feature is a cool AI-based tool that enhances the way content is consumed, especially for those who prefer audio formats.
PROVIDING ACCESS TO DOCUMENTS IN A NOVEL WAY
As LLMs are becoming multimodal, meaning they don’t just understand and generate text, they can also interpret images/video and audio, we’re getting some new benefits. AI-generated audio can turn any written content into audio so creators can reach new audiences who prefer listening over reading. This format is especially useful for commuters, multitaskers, or individuals who rely on audio content during activities like exercising or driving. Additionally, the conversational style of the AI-generated podcasts makes the material more engaging, as the natural-sounding dialogue, including pauses and laughter, mimics human conversation. This delivery can transform educational or informational content into something livelier and relatable. I am also using ChatGPT’s Advanced Voice mode more and more to have real-time audio conversations with AI in a very realistic manner.
This feature also opens the possibility of turning static written materials into a dynamic, on-demand knowledge hub. Creators can compile multiple blog posts or articles into a cohesive podcast series, making it easy for listeners to access a wealth of information in one place. Real-world applications extend to professionals in various fields, such as educators who can deliver lectures in podcast form, marketers creating audio summaries of reports, or researchers sharing insights through audio briefings. By using AI-generated audio, these professionals can present their material in new, engaging formats that align with modern content consumption trends. These audio formats can also provide greater access to information for the visually impaired.
Being able to interact with LLMs with voice capabilities expands the educational potential of AI – being able to have a real-time discussion with your homework documents presents another way to learn. I wish I had these tools when I was working towards my dissertation. Being able to upload 50 PDFs of complicated scientific articles and have a conversation with the documents, exploring methodologies, considering limitations, and meta-analyzing results would have been amazing. Even studying for a high-school government midterm could be more interesting and engaging with an AI-generated study guide, timeline of key events, and of course podcast on the powers of the executive branch that you will be tested on.
CONCLUSION: THE FUTURE OF AI-GENERATED AUDIO CONTENT
Google’s NotebookLM Audio Overview feature is a fun and practical leap in making content more accessible, engaging, and easily repurposed. The natural-sounding dialogues and the convenience of automated audio generation save time and broaden content reach. As AI-generated audio continues to evolve, this tool promises to reshape how creators deliver their content across multiple platforms. I encourage you to explore the Audio Overview feature, experiment with turning your content into podcasts and making your content more dynamic and accessible.
