Google finally realized 90% of the world doesn't speak English and maybe that's bad for business. NotebookLM now supports 80 languages for its video generation feature, which means you can finally get those AI-generated summaries without everything sounding like a Google Translate fever dream.
The video feature launched in July 2025 as English-only because of course it did. Non-English speakers have been stuck with garbage basic summaries while English users got the full experience with proper video presentations. About time Google fixed this.
Here's what actually changed: the audio summaries now work properly in other languages instead of giving you the abbreviated crap they served up before. You used to get maybe 2 minutes of basic overview if you were lucky enough to not speak English. Now you can actually get detailed breakdowns in French, German, Spanish, Japanese, and 76 other languages.
The rollout started August 25 and should hit everyone within a week. Whether the voice actually sounds natural in other languages or like robot garbage remains to be seen - Google's track record with non-English AI voices is mixed at best.
For anyone who's been waiting for NotebookLM to support their language since day one, this is actually useful. No more feeding everything through Google Translate first just to get a decent summary of your research documents. The multilingual support includes the full video generation pipeline, not just basic text summaries.
The NotebookLM app also got updated with these language features, and early users report mixed results on social media. Some languages like Spanish and French work well, while others still sound robotic.
Google's AI language models have been improving, but generating natural-sounding speech in 80 different languages is no joke. Implementation quality varies significantly by language family.
