First published in 1933, The Psychology of Effective Speaking studies voice as an expression of personality.

This book also criticises the education of its time, but not always destructively. It asks why, since people speak, they should not speak better. It suggests that if democracy is to succeed, rapid increase in the effectiveness of vocal communication is urgently necessary, and that this improvement begin in the lower classes of the schools. This book will be of interest to students of rhetoric, communication and psychology.
