Mark Twain is universally recognized as an important author in American literature, and in addition to his success as an author, he was equally successful as an oral interpreter. His career as an interpreter and lecturer commenced at the age of twelve in Hannibal, Missouri, and in later years expanded to cover the globe. Twain lectured throughout the United States, Europe, Australia, India, South Africa, England, New Zealand, Scotland, and Canada. Throughout his writings, Mark Twain included statements pertaining to his delivery of these lectures and platform readings, and he also included comments on techniques for oral interpretation in general.

The purpose of this study is to compare persons with trained voices and persons with untrained voices in their abilities to utilize tactile-kinesthetic feed-back when attempting to control vocal intensity.
