Google’s NotebookLM is testing a new “Lecture” audio mode, aiming to provide 30-minute AI-generated sessions. This feature, under development, includes language selection and a planned British English narration for enhanced learning experiences. NotebookLM's Audio Overview already engages users through two AI hosts, making complex topics accessible. This addition could benefit students and professionals alike by allowing detailed audio lectures tailored to their needs, although a launch date remains unspecified.
