Students and instructors in the Speech Arts have voiced the complaint that a full understanding of the structures and performances of the speech mechanism is exceedingly difficult, if not impossible of conveyance, by the employment solely of abstract descriptions. This is to be expected, inasmuch as the majority of these students have had no training in anatomy and physiology prior to entering speech courses. That a complete understanding of the peripheral speech mechanism should be a part of the education of every student in the Speech Arts on scarcely be doubted. Hence recourse to a medium which will supplement the abstract instruction to the end of providing completeness of understanding must be had. It follows that that medium must be in the nature of a graphic physical model-a visual aid.
