There's also a section of mark-up symbols for making notes on your copy for modulation.
This is good stuff, not only for the mark-up symbols but especially for the voice lessons within.
Language changes over time and many of the examples used in the book might be a bit dated. But, I found these forty-four pages to be some very valuable tools for me as a voice actor. Perhaps you will too. You can download the entire book for free from Barnes and Noble as a Nook book or as an eReader/PDF from Google Play-Google Books.

Archive.org also has a copy for free.
Check out Sanders' High School Reader by Charles Walton Sanders. Great material that has stood the test of time.
