NotebookLM multi-language upgrade: How to quickly organize data using Google Video/Audio Overview

Google recently announced another major update for its NotebookLM app: Video Overviews and Audio Overviews now support 80 languages. This means that users around the world, regardless of language, can now quickly transform notes, PDFs, images, and other materials into video presentations or audio summaries using NotebookLM, significantly improving learning and work efficiency.

This update is not only of great benefit to students and educators, but also a highly practical upgrade for multinational businesses, researchers, and multilingual learners. Below we'll detail the highlights of this feature update and provide a complete tutorial and application guide.

NotebookLM video overview: From English to global multilingual

Previously, NotebookLM's video overview feature was only available to English users, which made it difficult for non-English speaking users to use it. After this update:

• Covering 80 languages: including mainstream languages such as French, German, Spanish, Portuguese, Chinese, Japanese, Korean, etc., covering almost all major markets in the world.

• Diverse input materials: Not only can you upload notes, but it also supports PDF documents, pictures, reports and other materials. The system will automatically generate corresponding multilingual video demonstrations.

• Visual learning experience: The generated videos not only display key information but also help users understand complex content in an intuitive way, making them ideal for education and knowledge transfer.

This feature is particularly valuable for users who need to make presentations or teach. For example, teachers can directly convert handouts into multilingual videos that students can use to review key points of the course.

Audio Overview Optimization: More Natural Multilingual Summary

In addition to the video improvements, NotebookLM's Audio Overviews have also been upgraded:

1. Support for in-depth summaries: Previously, non-English users only had access to short audio content, and the full version was only available in English. Now, full in-depth summaries are generated for all 80 languages.

2. Free choice between brief and full versions: Users can choose a short summary (suitable for quick browsing) or a detailed version (suitable for in-depth learning) according to their needs.

3. More natural language expression: The optimized AI speech synthesis is smoother, avoiding the stiff translation tone and making the learning experience more comfortable.

This allows audio overviews to be used not only for learning, but also as a "portable learning assistant" during commuting or fragmented time.
