Observations on laryngeal disease, laryngeal behavior and voice

This discussion accepted the hypothesis that every laryngeal sound is produced by its unique type of vocal cord vibration. The production of vocal sound is not capricious, it follows certain laws many of which are not known. Research into the behavior of the larynx has produced some interesting and perhaps, useful findings. It was the intention of this paper to describe some of the features of laryngeal behavior as they relate to both phonation and laryngeal disorders in the belief that such knowledge lends itself to the more efficient management of certain vocal and laryngeal problems. The central theme has been that it is laryngeal behavior and not laryngeal disease itself that determines vocal deviation.
