AI总结:

本文评估了两种匿名化方法在隐私保护与帕金森病检测性能之间的权衡,发现kNN-VC在保留关键声学特征方面优于STT-TTS,为隐私保护下的PD检测提供了可行方案。

摘要:

自动从语音中检测帕金森病(PD)是一种有前景的非侵入式诊断工具,但其引发显著的隐私问题。说话者匿名化可以缓解这些风险,但可能会抑制用于PD检测的病理信息。我们评估了两种匿名化方法(STT-TTS和kNN-VC)在两个西班牙数据集上的隐私与PD检测之间的权衡。STT-TTS提供更好的隐私,但严重降级PD检测,通过消除语调信息。kNN-VC保留了宏语调特征,如持续时间和F0轮廓,其F1分数仅比原始基线低3-7%,证明了在使用适当匿名化时,隐私保护的PD检测是可行的。最后,对声音失真分析确定了kNN-VC的具体弱点,为设计更好地保留PD信息的匿名化方法提供了见解。

英文摘要:

Automatic detection of Parkinson's disease (PD) from speech is a promising non-invasive diagnostic tool, but it raises significant privacy concerns. Speaker anonymization mitigates these risks, but it may suppress the pathological information necessary for PD detection. We assess the trade-off between privacy and PD detection for two anonymizers (STT-TTS and kNN-VC) using two Spanish datasets. STT-TTS provides better privacy but severely degrades PD detection by eradicating prosodic information. kNN-VC preserves macro-prosodic features such as duration and F0 contours, achieving F1 scores only 3-7\% lower than original baselines, demonstrating that privacy-preserving PD detection is viable when using appropriate anonymization. Finally, an acoustic distortion analysis characterizes specific weaknesses in kNN-VC, offering insights for designing anonymizers that better preserve PD information.
