Google’s new Audio Overviews feature, now in testing, delivers podcast-style AI-generated summaries for search queries, making information accessible on the go.
Google announced it’s testing a groundbreaking feature called Audio Overviews in Google Search, designed to deliver AI-generated, podcast-style summaries for select search queries. Powered by the advanced Gemini 2.5 AI models, this feature aims to make learning more accessible and convenient, especially for auditory learners or those multitasking on the go. Currently available in Google’s Search Labs for users in the United States, Audio Overviews are set to redefine how we interact with search results. Here’s everything you need to know about this innovative tool, how it works, and what it means for the future of search.
What Are Audio Overviews?
Google’s Audio Overviews transform traditional search results into short, conversational audio summaries, typically lasting 30 to 45 seconds. Imagine searching for “how do noise cancellation headphones work?” and, instead of skimming through links, hearing a lively, podcast-style explanation from two AI-generated voices discussing the topic in a clear, engaging way. This feature builds on Google’s existing AI Overviews, which provide text-based summaries for certain queries, but takes it a step further by adding a hands-free, audio-driven experience.
The feature is currently in testing through Google’s Search Labs, an experimental platform where users can opt in to try new tools. When you search for specific informational queries, like “how does photosynthesis work?” or “what is blockchain technology?”, a “Generate Audio Overview” button appears below the “People also ask” section. Clicking it triggers the Gemini 2.5 models to create a concise audio discussion, complete with sources listed in an embedded player for transparency. Users can play, pause, mute, or adjust playback speed, making it easy to digest information while cooking, driving, or exercising.
How Do Audio Overviews Work?
Audio Overviews leverage Google’s Gemini 2.5 AI models, known for their advanced natural language processing and multi-speaker dialogue generation. When a user clicks the “Generate Audio Overview” button, the AI analyzes top search results and synthesizes a conversational summary between two virtual “hosts.” These AI voices, designed to sound natural and enthusiastic, mimic a podcast-style back-and-forth, breaking down complex topics into bite-sized explanations. For example, a search for “how do noise cancellation headphones work?” might produce a 40-second clip explaining active noise cancellation technology in simple terms.
The audio player includes links to the sources used, allowing users to dive deeper into the topic by visiting the original websites. Users can also provide feedback with a thumbs-up or thumbs-down rating to help Google refine the feature. The process takes up to 40 seconds to generate, ensuring the AI doesn’t waste resources unless the user explicitly requests the audio. Currently, the feature is English-only and available exclusively in the U.S., but Google plans to expand languages and regions in the future.
Building on NotebookLM’s Success
Audio Overviews in Search draw inspiration from Google’s NotebookLM, a research tool launched in 2023 that gained popularity for its Audio Overviews feature. In NotebookLM, users can upload documents, PDFs, or web links, and the AI generates podcast-style discussions based on the content. The Search version adapts this concept to public web results, making it more broadly accessible. Google’s blog post highlights that Audio Overviews are ideal for “auditory learners or those who want a convenient, hands-free way to absorb information.”
The technology behind Audio Overviews relies on Gemini 2.5’s multi-speaker dialogue generation, which creates realistic, engaging conversations. Google has rigorously tested these models for safety, using internal and external evaluations, including red-teaming, to ensure responsible deployment. This ensures the audio summaries are accurate, factual, and free from harmful biases.
Who Can Use Audio Overviews?
To try Audio Overviews, users must join Google’s Search Labs, a free experimental program accessible via the Google app or Chrome browser. Once enrolled, the feature appears for select queries deemed suitable for audio summaries, such as educational or explanatory topics. For example, searching “Google Audio Overviews” might even trigger an Audio Overview explaining the feature itself—a recursive twist that’s both clever and useful.
As of June 2025, the feature is limited to U.S. users and English-language queries, but Google’s track record of expanding AI tools—like AI Overviews, now available in over 200 countries and 40 languages—suggests broader availability may come soon. The feature requires no additional hardware, working seamlessly on smartphones, laptops, or any device with Google Search and audio playback capabilities.
Why Audio Overviews Matter
Audio Overviews cater to a growing demand for accessible, hands-free learning. Whether you’re a student studying for exams, a professional brushing up on industry trends, or someone curious about a new topic, this feature makes information more digestible without requiring you to stare at a screen. It’s particularly valuable for multitasking scenarios, like listening while commuting or working out, and for visually impaired users who rely on audio interfaces. Google’s emphasis on accessibility aligns with its mission to make information universally available.
However, the feature has sparked some debate. Posts on X highlight concerns from publishers, who worry that Audio Overviews, like AI Overviews, may reduce website traffic by delivering answers directly without requiring clicks. A Wall Street Journal report noted that AI-powered tools are already impacting news publishers, and Audio Overviews could exacerbate this trend. Google counters that it sends billions of clicks to websites daily and that Audio Overviews include source links to encourage further exploration.
Challenges and Future Potential
While Audio Overviews are promising ATPase: [2:36 PM] promising, they’re not perfect. Earlier reports of Google’s AI Overviews giving incorrect information, like stating the wrong year, raised concerns about accuracy. Google has acknowledged these issues and is actively refining its AI models to ensure factual reliability. The Audio Overviews feature benefits from Gemini 2.5’s improved reasoning capabilities, but ongoing feedback from users will be critical to fine-tuning its performance.
Looking ahead, Audio Overviews could evolve into a staple of Google Search, especially as voice-based interfaces gain popularity. With the global rise of podcasting and audio content, this feature taps into a cultural shift toward audio learning, potentially transforming how we consume information online.
A Step Toward the Future of Search
Google’s Audio Overviews mark a bold step in blending AI with user-friendly interfaces, offering a hands-free, engaging way to explore search results. By combining Gemini 2.5’s advanced AI with podcast-style delivery, Google is making information more accessible and dynamic. While challenges like publisher concerns and accuracy remain, the feature’s potential to enhance learning and multitasking is undeniable.
As Google continues to test and refine Audio Overviews, users can expect a smarter, more conversational search experience. For now, U.S. Search Labs participants can try it out, and the rest of the world may soon join in. Whether you’re curious about how quantum computing works or just want a quick explainer on the go, Audio Overviews are here to make search a little more human.
This feature underscores a broader trend in AI development—moving beyond static links and into real-time, conversational information delivery. As search becomes more auditory, contextual, and personalized, the role of AI will only deepen in how we explore and learn online.
