“Speak Up – A handbook for effective public speaking“, by Avi Shulman.
From Amazon’s blurb:
Avi Shulman has worked miracles with people who thought they were tongue-tied, who thought a microphone was as lethal as a hand grenade, who wanted to run whenever they saw an audience. His seminars on public speaking have shown thousands of people that they can express themselves in public – articulately, effectively, and even enjoyably! In this handbook, Avi Shulman shares a career’s worth of tips, techniques, and tricks of the trade. Everyone should learn to Speak Up – so why not learn to take the fear out of it and do it well? Everyone – even experienced speakers – will profit from the down-to-earth guidance in this rich little book. Try it – your audience will like it!
Well written and brief. The book has helped me.
