Nineteen authors contributed twenty-four essays on the anatomy, physiology and pathology of voice and speech. Among the speech disorders covered are aphasia, paragrammatism, infantile psychic deafness, acoustic disorders and treatment, rhinolalia, stuttering, cluttering and articulatory disorders resulting from gunshot injuries. Material on remedial reading and retraining of the speaking voice after laryngectomies is also included.
The editor states frankly that he made no attempt to correct inconsistencies among the various authors. Further, some of the essays are annotated and include bibliographies, and others lack these features. The result is a more or less uneven style.
Each essayist in turn is somewhat of a "special pleader," and the compilation might be quite confusing, as well as misleading, to a person not professionally trained in the field of voice and speech correction, since many of the authors were so limited in space that the didactic approach could not be used.
