In my opinion, these are the best available. Especially in terms of price/performance: e.g. this one: https://www.ipevo.com/products... Could you record them?

Since I travel a lot by train, I digitise a lot of documents and then read them on my tablet. Scanning books is rather difficult, not to say tedious, and that's why I thought about buying a book scanner like the Plustek OpticBook 4800. The feedback from customers online is quite good. Unfortunately, not all books and learning materials are available as e-books or I still have an old dictionary in 5 languages which I want to digitise but not destroy. With the smartphone and the app OfficeLens it works as a stopgap, but since the book pages are curved, the quality isn't great either. I also learn languages with Skype-learning tandem and for that I also scan very good picture books, which unfortunately are not available digitally. This way I can give the documents to my learning partners on the screen and we can work on them together. A fine thing ! Has anyone here found another solution for one of these topics? Thank you very much for your feedback.
