Acoustic analysis of the voice was used to facilitate diagnosis and to objectively evaluate results of the treatment of psychogenic dysphonia (PD) in 20 women. The control group comprised 20 women showing no signs of laryngeal pathology. The following parameters were measure: jitter, shimmer, signal to noise ratio, and response in the voicing test. Other methods applied included laryngoscopy, videolaryngoscopy, and laryngostroboscopy. It was shown that hoarseness in patients with PD results from the disturbances of mechanisms controlling stability of phonation. This observation is confirmed by the results of the acoustic test. It is concluded that dysphonia confirmed in the acoustic test in the absence of organic changes in the larynx is caused by psychogenic factors. Acoustic analysis of the voice is indicated to objectively evaluate results of the treatment of psychogenic dysphonia.
对20名女性的嗓音进行声学分析，以辅助诊断并客观评估癔症性发声障碍（PD）的治疗效果。对照组由20名无喉部病变迹象的女性组成。测量了以下参数：抖动、闪烁、信噪比和发声测试中的反应。应用的其他方法包括喉镜检查、视频喉镜检查和喉动态镜检查。结果表明，PD患者的声音嘶哑是由控制发声稳定性的机制紊乱所致。声学测试结果证实了这一观察结果。得出的结论是，在喉部无器质性改变的情况下，声学测试中确诊的发声障碍是由心理因素引起的。嗓音声学分析有助于客观评估癔症性发声障碍的治疗效果。
