Google AI podcast tool speaks 50 languages, including Zulu

Google‘s NotebookLM is expanding its popular AI-powered “Audio Overview” feature to 50 additional languages, addressing a growing demand for multilingual content transformation tools. This significant update to Google’s experimental AI notebook allows users to convert text into podcast-style conversations between AI hosts in languages ranging from Spanish and Zulu to Afrikaans, powered by Gemini 2.5 Pro. The feature’s ability to transform dense content into engaging, conversational formats has important implications for education, language learning, and cross-cultural content accessibility.

The big picture: Google is dramatically expanding the reach of NotebookLM’s viral Audio Overview feature by adding support for 50 new languages, making AI-generated audio summaries accessible to a much broader global audience.

• The update introduces a new “Output Language” option in settings, allowing users to change both audio and chat response languages at any time.
• The expansion is powered by Gemini 2.5 Pro, indicating Google’s commitment to leveraging its most advanced AI models for multilingual applications.

Key details: The Audio Overview feature transforms text content into podcast-style conversations between two AI hosts, making complex information more digestible and engaging.

• Users can now select from over 50 language options, including Spanish, Zulu, Afrikaans, and varieties of Chinese.
• The feature maintains high-quality, natural-sounding conversations even in non-English languages, according to early testing by a native Spanish speaker.

Practical applications: The multilingual expansion enables several new use cases that enhance learning and cross-language content accessibility.

• Content can be broken down for non-native English speakers, making information more accessible to diverse audiences.
• Language learners can practice by having their content output in their target language.
• Researchers and students can translate complex materials into their native language for better comprehension.

Why this matters: The timing aligns with Google’s announcement that students can access Google One AI Premium Plan for $20 per user per month, which includes NotebookLM’s premium tier with higher usage limits.

• This creates an educational ecosystem where students can access advanced AI tools for transforming and consuming content in their preferred language.
• The feature democratizes access to information by breaking down language barriers in educational and research contexts.
