This enhancement reflects Google's commitment to inclusivity and global accessibility in technology, aiming to make NotebookLM more accessible to a diverse audience.

The recent update allows users to interact with AI podcast hosts, creating a more immersive experience that enhances comprehension of the materials.

Since its launch in September 2024, the Audio Overviews feature has expanded to over 200 countries, allowing users to upload documents and generate engaging, podcast-like summaries.

An early user praised NotebookLM for its conversational tone and coherent organization of information, particularly noting its effectiveness in translating news content.

Potential applications of this feature include aiding non-English speakers and assisting language learners, as well as enabling content translation for users.

On April 29, 2025, Google announced a significant update to its NotebookLM, which now generates AI podcasts in over 50 languages, expanding from its initial English-only capability.

The update includes support for widely spoken languages such as Spanish, Hindi, and Brazilian Portuguese, alongside a complete list that features languages like Arabic, French, Japanese, and more.

Users can now select their preferred output language for audio and chat responses by adjusting settings in the app, facilitating multilingual content creation.

This functionality is particularly beneficial for busy listeners, language learners, and researchers, serving as a productivity enhancement tool.

Educators can leverage this feature to prepare multilingual resources for students, helping to break down language barriers in diverse educational contexts.

Google's ongoing investment in NotebookLM highlights its evolution from an experimental tool to a core resource for learning and research.

The company indicates that this expansion is just the beginning, with more languages expected to be added in the future.
