NotebookLM has recently expanded its audio overviews, providing accessibility in over 50 languages. This feature allows users to convert educational content from books into audio formats, aiding in learning and comprehension. The technology used involves scanning book pages and using GCP’s Document AI to extract and format the text into audio. Users like homeschooling parents find this feature beneficial, as it complements traditional learning methods by allowing kids to listen to content before class discussions. However, some users express concerns about the quality and detail of the generated audio, suggesting the underlying model needs improvement for accurate representation of complex texts.
