Abstract

In the present study, we empirically explore how the voice quality of depression patients (as experimental group) differs from that of healthy people (as control group), in terms of jitter, shimmer, HNR and pitch. Our analysis results reveal that the shimmer, maximum HNR and minimum HNR of patients are significantly different from those of the control group. Specifically, the patients tend to have a higher shimmer and lower maximum and mean HNR. To figure out to what extent the emotion has influenced the results, we further investigate whether there are significant differences in voice quality among different variations of emotion (positive, neutral, and negative) embedded in text reading. It turns out that no significant differences in voice hoarseness are found, showing that the voice quality is immune to emotion. Therefore, we can conclude that in general the voice of depression patients is hoarser than non-depressed people.

中国抑郁症患者语音质量分析

在本研究中，我们实证探讨抑郁症患者(实验组)与健康人(对照组)的语音质量在抖动、闪烁、HNR和音高方面的差异。我们的分析结果显示，患者的shimmer、最大HNR和最小HNR与对照组有显著差异。具体而言，患者往往有较高的闪烁和较低的最大和平均HNR。为了弄清楚情绪对结果的影响程度，我们进一步研究了文本阅读中嵌入的不同情绪(积极、中性和消极)在语音质量上是否存在显著差异。结果发现，在声音嘶哑方面没有明显的差异，这表明声音质量不受情绪的影响。因此，我们可以得出结论，总体而言，抑郁症患者的声音比非抑郁症患者的声音更沙哑。
