Speak Smart is a book looking at the techniques of public speaking. Speak Smart goes through all of the subtle things you don't think about when giving a talk, but really should. Things like speech preparation, how to talk (clarity, volume, etc), non-verbal communication, presentation formats are all covered.
Additional topics such as visual aids are looked at. My only problem with this book is that it is a little dated and didn't focus more on Powerpoint presentations, which is the defacto standard at most Universities. However additional sections of how to field questions from the audience, handling enemies, and how to prepare for a presentation make this an excellent read. The author also suggests other books for more information which I found to be invaluable.
The book is well laid out with the main points highlighted and repeat in a appendix for easy review. The author doesn't waste pages with useless information and his humor and wit make read this book very entertaining.
After my previous poor experiences with my last 2 Princeton Review books, I am happy to say that this is by far the best book in this series so far and I happily recommend it. 5 out of 5 stars.
