Val, thanks for searching. Yes, that person on YouTube did record reading the first two Harry Potter books aloud. She's not a professional but she did extremely well. She reads clearly and it is clear that she is having great fun reading the books aloud. She does voices well. Listening to her do Hagrid is a hoot. Sometimes the audio quality decreases. Obviously it was a labor of love and it definitely exceeds my expectations for a non-professional working alone (without sound editors and all). She is simply a delight to listen to. She reads rapidly so I need to play the audio at slightly reduced speed. There is a built-in YouTube setting for that. I have also had good results using WorkAudioBook, an app I will explain in a separate post. It has a free Windows version at http://workaudiobook.com/ There is an Android version (In-app purchases, not expensive) at https://play.google.com/store/apps/details?id=com.povalyaev.WorkAudioBook

I have never come across audiobooks of Harry Potter except for this post. In the post, you can find some YouTube recordings of the first book: https://www.reddit.com/r/hebrew/comments/jmj2yf/harry_potter_audiobook_in_hebrew/. Good Luck!
