This is a report of a comparative study of breathing and speech coordinations of laryngectomized and normal subjects. It also deals with the relationship between the breathing and speech coordinations and discusses articulatory errors of the laryngectomized subjects with reference to their speech intelligibility. Fifteen laryngectomized men between the ages of 36 and 74 (mean 59.9) years participated. The normal subjects were 15 men between the ages of 37 and 70 (mean 60.1) years. Several occupations were followed by the active and controlled groups, and some of the subjects were retired. Elaborate procedures were set up for the study. Among other tests, kymographic records of the breathing habits and tape recordings of the speaking voice of the laryngectomized men were made. Four types of pseudovoice are roughly identified as (1) pseudowhisper, (2) pharyngeal-voice, (3) esophageal-voice, and (4) gastric-voice. The authors investigated the anatomy of the throats of the patients to
