In a significant update, Google has expanded its NotebookLM platform to support Audio Overviews in more than 50 languages, including Bahasa Indonesia and Bahasa Jawa. This feature, which allows users to transform reference materials into engaging, podcast-like conversations, is now accessible to a broader audience following its launch to over 200 countries at the end of 2024.
The announcement, made on April 30, 2025, highlights Google's commitment to enhancing user experience by incorporating built-in audio support via its Gemini technology. "More people can use Audio Overview in their chosen language, from Afrikaans to Hindi to Turkish, and many more," a Google representative stated. This move not only broadens the reach of the feature but also makes it easier for users to engage with content in their native languages.
NotebookLM's Audio Overviews have quickly gained popularity since their introduction, as they convert traditional reference sources into dynamic audio formats, resembling engaging podcasts. This innovative approach caters to the diverse linguistic needs of users, ensuring that information is accessible and comprehensible.
One of the standout features of this update is the new 'Bahasa Output' option in NotebookLM settings. This allows users to select their preferred language for Audio Overviews and easily switch it at any time. As noted by Google, "You can change the language anytime, and your audio and chat responses will reflect this, making it easier to create multilingual content or educational materials as needed." This flexibility is particularly beneficial for educators and students alike.
For instance, a teacher preparing a lesson on the Amazon rainforest can compile various resources in multiple languages—such as Portuguese, Spanish, and English—and share them with students. Students can then upload these materials to generate an Audio Overview in their preferred language, enhancing their understanding and engagement with the subject matter.
This feature not only aids in language learning but also helps break down language barriers, making valuable information more accessible to a global audience. By allowing students to create Audio Overviews of research papers or studies in foreign languages, Google is empowering learners to deepen their insights and broaden their academic horizons.
As Google continues to refine and expand the capabilities of NotebookLM, users can expect ongoing improvements and additional language support. The company has expressed its dedication to building and enhancing this feature based on user feedback, ensuring that Audio Overviews remain a vital tool for learning and information dissemination.
In summary, the introduction of Audio Overviews in over 50 languages marks a significant milestone for Google’s NotebookLM platform. This feature not only enriches the user experience but also fosters a more inclusive environment for learners around the world. With the ability to easily switch languages and create engaging audio content, Google is paving the way for a more connected and informed global community.
