Reviewer: Jiri Mazoch from Czech Republic
When I read about Valsalva hypothesis for the first time in an article by Mr. William Parry on the internet, I decided to buy the book "Understanding & Controlling Stuttering" to learn more about this mechanism. The book is very well written from the beginning till end. The explanation of the speech mechanism, the basics of speech, speech functions of the brain, the Valsalva mechanism and all information are written in intelligible terms. The exercises for Valsalva and speech control are very well proposed. I was always puzzled why I spoke fluently in some situations and was not able to say a single word in other ones. I knew I gave much effort to my speech. The Valsalva hypothesis is the most precise description of my stuttering I have ever encountered. I am severe stutterer and exercises described in this book improved my fluency and I hope this improvement will continue. This is the most interesting book about stuttering I have read and I recommend it to anyone who stutters.
