摘要:

准确预测心脏活动及其他生物信号对于诊断和监测至关重要。鉴于语音是多个生理系统共同作用的结果,已有大量工作研究了心脏活动的声学相关性。近年来,自监督模型在语音相关任务中相比传统声学方法表现出色。然而,数据驱动表示在预测心脏活动方面的鲁棒性仍未得到探索。在本研究中,我们证明自监督语音模型在预测心脏活动参数方面优于声学特征。我们还强调了个体差异对模型泛化能力的影响。这些发现凸显了数据驱动表示在此类任务中的价值,并表明需要更多基于语音的生理数据以缓解与说话人相关的挑战。

英文摘要:

Accurately predicting heart activity and other biological signals is crucial for diagnosis and monitoring. Given that speech is an outcome of multiple physiological systems, a significant body of work studied the acoustic correlates of heart activity. Recently, self-supervised models have excelled in speech-related tasks compared to traditional acoustic methods. However, the robustness of data-driven representations in predicting heart activity remained unexplored. In this study, we demonstrate that self-supervised speech models outperform acoustic features in predicting heart activity parameters. We also emphasize the impact of individual variability on model generalizability. These findings underscore the value of data-driven representations in such tasks and the need for more speech-based physiological data to mitigate speaker-related challenges.
