The dialogue format helps break up dense content material right into a vigorous dialog, making it extra digestible and particularly nice for learning or understanding content material totally — and it’s now coming to extra languages.
On Tuesday, Google introduced that Audio Overview is increasing to over 50 extra languages, powered by Gemini 2.5 Professional. The whole listing contains Spanish, Afrikaans, and extra. You possibly can hear the 2 Audio Overview AI hosts break down the information within the YouTube video beneath.
The replace features a new “Output Language” possibility in NotebookLM’s settings. This selection lets you change the language of the audio and chat responses anytime, making it simpler to create content material in one other language.

I can affirm that it was all correct within the details and the conversational ad-libs round it.
I discovered this function to be essentially the most fascinating addition to NotebookLM as a result of, as somebody who has written articles in Spanish earlier than, at the same time as a local Spanish speaker, it may be difficult. Information makes use of language you do not essentially use in colloquial speech, making it onerous to translate, particularly as a result of English-to-Spanish literal translations usually do not imply the identical factor. NotebookLM managed to maintain it conversational, manage the content material in a digestible means, and add facet feedback, whereas staying true to the unique textual content.
