This study investigated the relationship between pathologic and normal speaking fundamental frequency characteristics (SFF) in a group of 80 male subjects. The subjects were divided into four groups of 20 (1) vocal fold paralysis, (2) benign mass lesion, (3) cancer of the larynx, and (4) normal. The results of this study indicate that SFF standard deviation and semitone range of SFF are significantly reduced for patients with vocal fold paralysis as compared with normals. The parameters of mean SFF, number of frequency shifts, and age failed to separate the normals from the three groups of pathologic subjects.
本研究调查了80名男性受试者的病理性和正常言语基频特征（SFF）之间的关系。受试者被分为四组，每组20人：（1）声带麻痹组，（2）良性肿块病变组，（3）喉癌组，（4）正常组。本研究结果表明，与正常组相比，声带麻痹患者的SFF标准差和SFF半音范围显著降低。平均SFF、频移次数和年龄等参数未能将正常组与三组病理性受试者区分开来。
