用情绪感知语音识别抑郁症状,让分析更贴近临床。
Clinically Inspired Symptom-Guided Depression Detection from Emotion-Aware Speech Representations
- 通过症状引导的注意力机制对齐问卷与语音特征。
- 在EDAIC数据集上优于已有方法,提升诊断准确性。
- 可解释性强,能定位多症状共现的语音片段。
抑郁症表现为睡眠障碍、兴趣减退、注意力不集中等多种症状。现有研究多将抑郁预测视为二分类或总体严重程度评分,未显式建模症状特异性信息,限制了其在临床筛查中的应用价值。为此,本文提出一种基于症状引导和临床启发的抑郁严重度评估框架,利用症状引导的交叉注意力机制,将PHQ-8量表条目与情绪感知语音表示对齐,识别出与各症状相关的语音段落。为捕捉症状表达的时间差异,引入可学习的症状特异性参数,自适应调节注意力分布的锐度。在标准临床数据集EDAIC上的实验表明,该方法性能优于先前工作。进一步分析显示,包含多个抑郁症状线索的语句获得更高注意力权重,凸显了模型的可解释性。研究强调了症状引导与情绪感知建模在语音抑郁筛查中的重要性。
原文摘要 · Abstract (English)
Depression manifests through a diverse set of symptoms such as sleep disturbance, loss of interest, and concentration difficulties. However, most existing works treat depression prediction either as a binary label or an overall severity score without explicitly modeling symptom-specific information. This limits their ability to provide symptom-level analysis relevant to clinical screening. To address this, we propose a symptom-specific and clinically inspired framework for depression severity estimation from speech. Our approach uses a symptom-guided cross-attention mechanism that aligns PHQ-8 questionnaire items with emotion-aware speech representations to identify which segments of a participant's speech are more important to each symptom. To account for differences in how symptoms are expressed over time, we introduce a learnable symptom-specific parameter that adaptively controls the sharpness of attention distributions. Our results on EDAIC, a standard clinical-style dataset, demonstrate improved performance outperforming prior works. Further, analyzing the attention distributions showed that higher attention is assigned to utterances containing cues related to multiple depressive symptoms, highlighting the interpretability of our approach. These findings outline the importance of symptom-guided and emotion-aware modeling for speech-based depression screening.
