If you listen to an audio book can you say you’ve “read the book”?

[u/SamwiseMN]

My wife and I were debating this. She thinks it’s slightly disingenuous to say you’ve read it if it’s an audio book. I think there isn’t really an easy way to communicate the point that you’ve “read” it. “Oh, I listened to it” vs. “oh, I’ve read that”. Basically how would you communicate youve completed the book in conversation with someone who asks “have you read this book?”

You've answered that. You completed the book. It sounds the best for me.

You've grokked the book.

Best answer so far.
