摘要:

抑郁症是世界范围内常见的精神障碍,会导致一系列严重后果。抑郁症的诊断依赖于患者报告的量表和精神科医生的访谈,这可能会导致主观偏见。近年来,越来越多的研究者致力于语音中抑郁的识别,这可能是一个有效而客观的指标。为了提高抑郁症识别的准确率,提出了一种基于决策树的语音段融合方法,并在52名受试者(23名抑郁症患者和29名健康对照者)的样本上进行了验证。在性别依赖模型下,男性和女性的识别准确率分别为75.8%和68.5%。从数据可以看出,所提出的决策树模型可以提高抑郁症的分类性能。

英文摘要:

Depression is a common mental disorder worldwide which causes a range of serious outcomes. The diagnosis of depression relies on patient-reported scales and psychiatrist interview which may lead to subjective bias. In recent years, more and more researchers are devoted to depression recognition in speech , which may be an effective and objective indicator. This study proposes a new speech segment fusion method based on decision tree to improve the depression recognition accuracy and conducts a validation on a sample of 52 subjects (23 depressed patients and 29 healthy controls). The recognition accuracy are 75.8% and 68.5% for male and female respectively on gender-dependent models. It can be concluded from the data that the proposed decision tree model can improve the depression classification performance.
