NotebookLM might be one of Google’s smartest tools you’ve barely used. It first made waves—not for its research chops—but for its Audio Overviews feature. Instead of dumping information at you, it turns your source material into podcast-style recaps that actually sound like real people talking, not robots reading a script. After popping up in the Gemini app and Discover’s Daily Listen, Google is now testing these AI-driven audio recaps right on the front page of mobile Search.
In a blog post, Google shared that Audio Overviews will tap into its latest Gemini models to offer a fresh, hands-free way to take in information. Right now, it’s a US-only Search Labs experiment and only works in English (via 9to5Google). Once it’s turned on, you’ll see a “Generate Audio Overview” button pop up during searches. Hit it, and you’ll get a clean little audio player with play/pause controls, volume, and speed options.
Google says the option to generate an Audio Overview won’t always show up, as it depends on whether it thinks your search actually needs one. But here’s the odd part: the button is kind of buried. It shows up way down the results page, tucked below the AI Overview, ads, a pile of regular links (plenty from Reddit), and even the full “People also ask” block. So, don’t expect it front and center.
As per the blog post, whipping up an Audio Overview can take up to 40 seconds while it pulls information, builds the voice, and pieces everything together. If your search is super niche or a bit complex, expect it to take even longer.
Google’s quiet pivot to a voice-first Search future?
Just like in NotebookLM and Gemini, this version brings in a duo of AI-generated “hosts” who break down your topic in a lively, back-and-forth style. And for those who like to double-check the details, Google adds extra transparency by dropping direct links to some of the sources used, right under the audio player.
With this experiment, Google is nudging Search into a more voice-first, semi-hands-free future. More importantly, it’s a big win for users with visual impairments. For now, though, think of this as a cool side feature—not a shortcut to skip the full story. Until Google nails the accuracy, it’s more of a teaser than a trusted takeaway.
