What are your thoughts on the new "Generate lesson audio" feature?

So it seems that with this new feature we are finally able to “create” audiobooks to accompany our reading. This is specially beneficial considering that sometimes there is written material which is not available in its audiobook version.
However, I would like to hear your thoughts on this because I know that a robot voice is not the same as an actual recorded human voice. So far I’ve been using this feature for German and I think the pronunciation is good enough but the rhythm and intonation feel still kind of robotic.
Maybe I’m going to use this feature to read and listen to at the same time a 1000 page book which, for obvious reasons, doesn’t have an audiobook. Do you think this would be a good idea? Or should I keep using audio material with authentical and natural human voices in order to work my comprehension skills?
