I'm really dissapointed, this is the exact same audio that you can find online with the free PDF download of the book available to everyone. At the very least I had expected the whole book, even the English descriptive pieces to be spoken so I wouldn't have to follow along with the book. Narrator is fine, very mechanical monotone but given the content that is expected. I'm overall not happy with this purchase. If your purpose is to just grasp the pronunciation while reading the book this might be helpful to you.
