Google’s AI podcast tool just got a serious upgrade. NotebookLM’s Audio Overview feature, known for turning documents and notes into conversational audio, now supports more than 50 languages—offering global users a new way to listen, learn, and share in their own tongue.

AI podcast hosts can now speak your language

Audio Overview has always stood out for its casual tone. It doesn’t drone like a textbook narrator—it chats, jokes, and pauses like a real host. Now, that same vibe can play out in French, Korean, Spanish, or dozens of other languages thanks to a new Output Language setting.

The feature is powered by Gemini 2.5 Pro, Google’s advanced large language model. Users can now generate multilingual summaries of any uploaded content—whether it’s a student study guide, a business brief, or a research deep dive—with just a few clicks.

Google’s AI podcast tool breaks language barriers

This isn’t just a gimmick. Language has long been a roadblock in making tech accessible worldwide. With this update, users can create audio summaries tailored for friends, students, or colleagues without relying on clunky machine translation or expensive human help.

Teachers can now upload mixed-language materials and generate recaps in whatever language suits their classroom. Researchers can get overviews delivered in their native dialect. It’s the kind of flexibility that could quietly reshape how people use AI for learning.

NotebookLM still in beta—but it’s growing fast

Google admits the tool isn’t perfect yet. Some languages are prone to awkward phrasing or mistranslations, and the AI voices may stumble in unfamiliar territory. But even with the quirks, the tool keeps its trademark style—expressive, engaging, and not afraid to crack a joke about your 10-page source doc.

What makes it work isn’t just the translation—it’s the tone. Audio Overview doesn’t sound like a tool reading a list. It sounds like two digital hosts riffing about your notes, complete with chuckles and curious inflections. That keeps listeners engaged, no matter the language.

AI podcast summaries go truly global

Google’s push toward multilingual support isn’t flashy, but it’s foundational. By giving AI a multilingual voice, the company is reaching people who’ve long been shut out of experimental tech features.

And yes, if you want your Roman history notes read back to you in Latin—NotebookLM can now do that, too. Whether you’re a teacher, a researcher, or just someone learning a new language, these AI voices might soon be your favorite polyglot podcasters.
