I didn't know about this, thanks! I just tried one; to my ears it is much less engaging vocally. I like the extra detail though. I'd probably personally prefer to tune NotebookLM's technicality of audience if I could. I'd also like different speakers - I wouldn't be surprised if we all will recognize the NotebookLM speakers instantly in a year or so.
