Google Expands AI-Powered Audio Overviews to Over 50 Languages

Google's AI podcast maker is now available in over 50 languages

Emma Roth is a news writer who covers the streaming wars, consumer tech, crypto, social media, and much more. Previously, she was a writer and editor at MUO. Audio Overviews, the AI tool that turns your research into podcast-like conversations in Google's NotebookLM app, is expanding beyond English. Now you can generate and listen to Audio Overviews in more than 50 languages, including Spanish, Portuguese, French, Hindi, Turkish, Korean, and Chinese. You switch to a different language by heading to NotebookLM, selecting your settings in the top-right corner of the screen, and choosing Output Language. From there, you can select from a list of languages, allowing you to receive responses and hear Audio Overviews in the language of your choice. Google says this is only "an early look at what's possible with this feature," adding that it plans to continue "building and refining it" based on feedback. Since launching Audio Overviews last year, Google has expanded it to more than 200 countries and added a range of new features, giving you the ability to "guide" the AI hosts of the conversation and even interact with them. Google has also brought Audio Overviews to its Gemini AI chatbot and Google Docs, allowing you to convert even more kinds of written material into AI podcasts.

Google's viral AI podcast tool can chat in 50 languages now and it aced my Spanish test

I made a Spanish AI podcast with NotebookLM's expanded language skills, and it's surprisingly good. Here's what else it can do. Google's experimental AI notebook, NotebookLM, went viral because of its Audio Overview feature, which transforms text content into a podcast with two AI hosts. The discussion format helps break up dense content into a lively conversation, making it more digestible and especially great for studying or understanding content thoroughly -- and it is now coming to more languages. Also: A few secretive AI companies could crush free society, researchers warn On Tuesday, Google announced that Audio Overview is expanding to 50 more languages, powered by Gemini 2.5 Pro. The complete list includes Spanish, Zulu, Afrikaans, and more. You can hear the two Audio Overview AI hosts break down the news in the YouTube video below. The update includes a new "Output Language" option in NotebookLM's settings. This option allows you to change the language of the audio and chat responses anytime, making it easier to create content in another language. Also: Why I just added Gemini 2.5 Pro to the very short list of AI tools I pay for Potential use cases include breaking down content for someone whose first language is not English, learning a new language by having your content output in the language you are learning, and even translating content, such as research, into your own language. I was given early access to the feature and was impressed with its accuracy and ease of use. First, I went to settings and changed the output language to español (latinoamerica). Then I uploaded a PDF of the Google I/O 2025 preview article I wrote and clicked on "Audio Overview." Although it took longer to generate the AI podcast than when I created it in English, it was still under five minutes. As a native Spanish speaker, I was pleasantly surprised by how natural the conversation sounded and how well it stuck to the news. I can confirm that it was all accurate in the facts and the conversational ad-libs around it. I found this feature to be the most fascinating addition to NotebookLM because, as someone who has written articles in Spanish before, even as a native Spanish speaker, it can be challenging. News uses language you don't necessarily use in colloquial speech, making it hard to translate, especially because English-to-Spanish literal translations typically don't mean the same thing. NotebookLM managed to keep it conversational, organize the content in a digestible way, and add side comments, while staying true to the original text. Also: The top 20 AI tools of 2025 - and the #1 thing to remember when you use them The full list of languages include: Afrikaans, Arabic (Egypt), Azerbaijani, Bulgarian, Bengali, Catalan, Czech, Danish, German, Greek, Spanish (European), Spanish (Latin American), Spanish (Mexico), Spanish (US), Estonian, Basque, Persian, Finnish, Filipino, French (European), French (Canada), Galician, Gujarati, Hindi, Croatian, Haitian Creole, Hungarian, Armenian, Indonesian, Icelandic, Italian, Hebrew, Japanese, Javanese, Georgian, Kannada, Korean, Konkani, Latin, Lithuanian, Latvian, Maithili, Macedonian, Malayalam, Marathi, Malay, Burmese (Myanmar), Nepali, Dutch, Norwegian Nynorsk, Norwegian (Bokmål), Oriya, Punjabi, Polish, Pashto, Portuguese (Brazil), Portuguese (Portugal), Romanian, Russian, Sindhi, Sinhala, Slovak, Slovenian, Albanian, Serbian (Cyrillic), Swedish, Swahili, Tamil, Telugu, Thai, Turkish, Ukrainian, Urdu, Vietnamese, Chinese (Simplified), Chinese (Traditional). This news is particularly timely as Google announced last week that students get access to Google's One AI Premium Plan, which costs $20 per user per month, which includes access to the NotebookLM premium tier. NotebookLM Plus offers premium, subscriber-only features and five times higher usage limits to some of NotebookLM's best features, including Audio Overview, notebooks, queries, and sources per notebook.

Google's fantastic virtual podcast tool just learned how to speak basically every language

Now Google's giving Audio Overviews a big accessibility boost, with support for output in over 50 languages. Call us a broken record by now, but the Audio Overviews Google initially cooked up for NotebookLM may just be the coolest thing we've seen from the company's AI efforts over the past couple years. A little over a month ago, Google helped introduce these same podcast-like audio summaries to an even larger audience by baking them in to Gemini itself. It's already incredibly impressive how the system is able to break topics down and communicate them in an easy-to-grasp manner, and now Google's got a big expansion to share that's only going to make Audio Overviews even more accessible.

Google is turning your favorite AI podcast hosts into polyglots

The Gemini 2.5 Pro-powered feature maintains the same casual, conversational style regardless of language It seems the AI 'podcasters' you create with Google's NotebookLM have been playing a lot of Duolingo. The AI-generated hosts of the Audio Overview feature can now perform in more than 50 languages. Audio Overview is the NotebookLM feature that transforms the documents, videos, books, and other information you give it into an audio show hosted by a couple of AI voices. When you make the Audio Overview now, you can go to the settings and pick an Output Language ahead of generating the audio. You can also switch languages on the fly, generate summaries for friends or students in their native tongue, or prep multilingual study guides without hiring a translator or braving the often messy results of Google Translate. The addition may not seem like a big deal among other AI spectacles, but it's potentially huge. Language plays a gatekeeper for so many things, especially technology. Now, Google can entice those who might be interested in playing with its AI toy without them having to learn a whole new language. An entire global audience of people studying, teaching, researching, or just interested in learning new things can now better navigate a Google platform previously limited by English exclusivity. Teachers, for instance, can upload a hodgepodge of resources in different languages and generate a digestible audio recap in whatever language their students are most comfortable with. The feature is only in beta, and Google is keen to caution that there are still some problems. The voices might stumble, and you might encounter weird or wrong translations, especially in less frequently used languages. But the synthetic personalities will still discuss your research paper sources or complete home makeover guide and riff, recap, and remark on the content; it's just that English won't be the only tongue they do it in. That tone matters. One of the reasons Audio Overviews clicked with users in the first place is that they don't sound like a monotone robot trying to teach you tax law. The AI hosts crack jokes, pause for effect, and express amazement in (usually) appropriate spots. There's something deeply satisfying about hearing your own research about ancient Rome explained to you in Latin. It definitely makes learning the language feel more exciting.

Google adds Spanish and French to NotebookLM in huge language update

NotebookLM is one of Google's lesser-used AI products but it introduced a feature that's becoming increasingly popular -- Audio Overviews. The company already brought it over to Gemini and plans to add the feature to Google Docs in the next few months too. Until now, Audio Overviews has been an English-only tool but as of this week, it's available in over 50 languages. The NotebookLM platform is all about putting together notebooks of information and different sources and using LLMs to interact with them. Audio Overviews is basically a fancy summary tool -- it lets you generate audio summaries of your selected sources that are presented in the style of a podcast with two AI hosts. Recommended Videos Though you could always use source material in any language to generate an Overview, the audio content was previously only available in English. Now, you can easily switch to Spanish, French or any of the 50+ languages Google has added this week. This will make it really easy to consume just about any content without having to search out translations in your preferred language. You can listen to an Audio Overview of a brand-new Japanese research paper that hasn't been translated yet, or consume super-niche English content that hasn't been translated to Spanish. This also combines the feature's original benefit of summarizing and simplifying content so you can get the gist of something really long or complex in a much quicker and more accessible format. Since NotebookLM is marketed primarily as a study tool, it also occurs to me that this feature could be great for language learning. Consuming familiar content in your target language is a really accessible way to start boosting your comprehension skills. For reading, for instance, it's really common for people to pick up the "Harry Potter" books in their target language because everyone knows the story. For listening, you can take whatever kind of written information you're familiar with and convert it into a podcast in your target language to listen along to. A new "Output Language" option has also been added so you can easily switch between languages at any time and create multilingual content. Google's blog post about the update focuses on NotebookLM specifically, and it seems the additional languages aren't available for Gemini yet. If you don't want to wait, NotebookLM is available for free and anyone on Google's One AI Premium plan also has access to NotebookLM Plus. Please enable Javascript to view this content

NotebookLM now makes AI podcasts in dozens of new languages

Google's AI-based note-taking and research assistant NotebookLM has expanded its Audio Overviews feature to 76 new languages, the company announced on Tuesday. This feature, launched last year, allows users to generate a podcast with AI virtual hosts based on documents shared with NotebookLM. The Audio Overviews feature is designed to help users digest and comprehend information in uploaded documents. With this expansion, users can now access Audio Overviews in their preferred language. Previously, Audio Overviews were generated in the user's account preferred language. Google has introduced a new "Output Language" option, allowing users to choose the language for their Audio Overviews. This change enables users to create multilingual content or study materials as needed. Users can change the language at any time. For example, a teacher preparing a lesson on the Amazon rainforest can share resources in various languages, such as a Portuguese documentary, a Spanish research paper, and English study reports, with their students. The students can then upload these resources and generate an Audio Overview of key insights in their preferred language.

Google's NotebookLM Can Now Generate AI Podcasts in Over 50 Languages

You can change the output language for AI podcasts under Settings of your NotebookLM project. Google's standout product, NotebookLM, which went viral for generating natural-sounding AI podcasts, now supports over 50 languages. Previously, NotebookLM could generate AI podcasts only in English. However, with the latest update, NotebookLM can now generate Audio Overviews aka AI podcasts, in over 50 languages such as French, Hindi, Japanese, Portuguese, and more.

Now, the AI podcast will be generated in your chosen language. Even if you have uploaded your documents in English or another language, you can choose a different output language for the AI podcast. I generated an AI podcast in another language in NotebookLM, and it did a wonderful job. By the way, NotebookLM uses Gemini's native multimodal capability to produce AI podcasts in different languages. Recently, Google added the ability to join the AI podcast and interact with AI hosts, which makes the experience even more immersive. Not to mention, you can now add relevant sources from the web to NotebookLM by describing what information you need. This way, you can add the latest information from the web to create an expansive knowledge base.
