Abstract

Introduction: Adductor spasmodic dysphonia (ADSD) is characterized by involuntary laryngeal muscle spasms. Due to the lack of a quantitative evaluation method, most measurements have demonstrated difficulty in validity and reliability for diagnosing ADSD. This study aimed to establish a novel indicator for ADSD and determine its diagnostic effects.

Methods: We investigated 98 voice samples from 49 patients with ADSD and 49 healthy participants. A sustained vowel was recorded by a high-definition audio recorder. Voice samples underwent regular acoustic evaluation and a novel global dimension (GD) method. GD, Jitter, Shimmer, HNR, Frequency shift, and CPPS were measured for both groups.

Results: Statistical analysis revealed that the GD method effectively differentiated ADSD patients from healthy participants (p < 0.001, D'>0.8). Subsequent multiclass receiver operating characteristic analysis demonstrated that GD possessed the most significant classification accuracy (area under the curve = 0.988) compared with other acoustic parameters.

Conclusion: GD was an effective metric for objective differentiation between ADSD patients and healthy participants. This metric could assist clinicians in the diagnosis of ADSD patients.

诊断扩张性痉挛性发音障碍的一种新的声学评价方法。

引言：外收肌痉挛性发音困难（ADSD）的特点是不自主的喉肌肉痉挛。由于缺乏定量评估方法，大多数测量结果在诊断ADSD的有效性和可靠性方面都存在困难。本研究旨在建立一种新的ADSD指标并确定其诊断效果。方法：对49例ADSD患者和49例健康人的98份语音样本进行调查。高清晰度录音机记录了一个持续的元音。对语音样本进行了常规声学评估和一种新的全局维度方法。测量两组的整体维度（GD）、抖动、Shimmer、HNR、频移和CPPS。结果：统计分析显示，全局维度方法有效地区分了ADSD患者和健康受试者（P0.8）。随后的多类别受试者操作特征分析表明，与其他声学参数相比，GD具有最显著的分类准确度（AUC=0.988）。结论：GD是客观区分ADSD患者和健康人的有效指标。这一指标可以帮助临床医生诊断ADSD患者。
