Answer by Yannick Rondeau:
It might not be the best book and, to be frank, i didn’t read it all yet. The advantages are that it is an audiobook so you can listen to it while doing some other important tasks and it’s free like every other books you can download on LibriVox.
The Art of Public Speaking
The Art of Public Speaking by Dale Carnegie and Joseph B. Esenwein is a manual for people who have to speak in public, and it is still in use today. Whether the occasion in question is sharing travel experiences with friends, a toast for newly-weds, or a public debate, the tips and tricks collected in this book will come handy anywhere.
The book describes how to make effective use of one’s voice and gestures, how to gain and convey confidence in front of a large audience, and which methods to use to convert the listeners to one’s own cause. Each chapter contains examples and a list of practice exercises. The last 15 sections are real speeches by famous men to function as a study aid. (Summary by Availle)
