Do you want to learn the lost secret of speaking perfect English? The "moving mouth dictionary" technique offers a simple approach to perfecting English speaking and pronunciation. This book takes a practical approach to speaking clear English, bringing fresh air into the often-stuffy world of academic learning. It is designed to help students and businesspeople speak impressively and naturally, taking much of the guesswork out of pronunciation and spelling. English will become more of a physical activity rather than an academic subject. The key lies in identifying and improving specific reverse and forward mouth movements and actions, using simple vertical mouth movement notations associated with key phonetic sounds for specific letters. The technique's forward and reverse mouth movements, combined with natural English rhythm, also help trigger vocabulary, aid word retention, and improve fluency and autocorrection. This book also includes a dictionary of over 11,000 words, featuring some of the most difficult words in the English language, broken down into "mouthables" using these notations. The process draws heavily on early humans' natural ability to howl and growl, using their mouths vertically. Rediscovering this lost connection with our ancestors can aid in speaking clear English-an ability we need to recover.
