Just insert any note, audio or video file into Google NotebookLM, and it will generate an audio file with two AI hosts discussing the content in the files. It can also discuss topics more specifically and among the new features is that users can interrupt the AI host's discussion and continue chatting or asking them something as if you were making a phone call to a radio station.
This feature, however, is not for launch. Google needs to train the AI hosts with the appropriate friendliness tuning to be more friendly like friends. Otherwise, the chatting or asking feature will make the AI hosts feel annoyed with humans. Google trains the AI hosts by doing real-world simulations of what it would be like if a group of people were having a discussion and one of the members interrupted.
Anyway, NotebookLM is one of the generative AI features that I really like to use. Just insert any document or article and the AI host can have an interesting discussion as if listening to a real podcast.
