Google NotebookLM Gets Four New Audio Overviews Formats With New AI Voices
NotebookLM is now offering four new Audio Overviews formats to let users customise the AI-generated audio discussions. The four new formats are dubbed Deep Dive, Brief, Critique, and Debate. Each of these new formats features a new artificial intelligence (AI) voice, but not all of them come with two AI hosts.
