喉頭疾患患者の話声位について

抄録

The author had developed a new analytic method of voice, using a microcomputer, which can show speaking fundamental frequency, speaking range and type of speaking. In this report the analysis of 300 cases with laryngeal disease was performed by this new method, both pre-and postoperatively. The type of speaking presented this time was classified into following 4 types,-mountain type, two peaks type, one peak type and pole type. There are good agreement between the results of measurement of speaking fundamental frequency using a new computer method and the results of mesurement of that using acoustic psychological method. There are no remarkable change either in the patients with vocal cord polyp or laryngeal nodule following operation.
