Google Notebook LM is a note-taking and learning tool using artificial intelligence, and has just introduced a notable new feature, the sound lecture mode.
This is considered the next step in an effort to turn user personal documents into easily accessible learning content, especially suitable for passive listening.
Previously, Notebook LM attracted great attention thanks to its ability to convert document files uploaded by users into podcast-style conversations.
AI voices naturally discuss the content, creating the feeling of listening to a real academic exchange.
The impressive difference is that users can even participate in this conversation, ask questions and receive feedback in real time.
However, with the Lecture mode, Google chooses a different direction. Instead of dialogue, the system creates a clear-structured audio presentation, using only one voice, mimicking the traditional lecture method in the classroom.
Users can choose "Short, Default or Long" in which the longest version lasts about 30 minutes.
The goal of the new mode is not continuous interaction, but an immersive experience. The reading voice is designed to be regular, slow and calm, limiting emotional or dialogue elements.
For some people, this presentation may be a bit dry; but for others, this is an ideal choice to listen to while working, moving, or relaxing.
According to reports from within Google, Notebook LM is also testing English-accented reading voices for lecture mode.
A post on the X platform from members of the development team said that users may be very interested in this option. In popular perception, English accents often evoke standards, calmness and prestige, which are elements suitable for academic content.
The combination of lecture format and English-style reading voice can create the feeling of listening to a professor present a lesson, even if the actual content is only synthesized from personal notes.
This shows that Google is not only focusing on content, but also strongly focusing on the listening experience.
Overall, the Lecture mode marks an important shift of Google Notebook, from an interactive experimental tool, to the image of a patient, methodical and long-term lecturer "digital teacher".
With the trend of flexible learning becoming increasingly popular, this feature may open up a new approach to knowledge absorption in modern digital life.
