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.

As we all know, finding out you have any form of terminal illness is a scary prospect. It may sometimes seem difficult to be positive minded & find a way to get through it. Nowadays, technology is evolving rapidly, and the help and development of new technology in treatment is helping people not only live longer but determine the most effective way to treat their illness. There are some crazy but amazing technologies out there that help medical professionals monitor and prevent ill health. MC10 develops a Bio stamp that is'thinner than a plaster', which can monitor temperature, sense any movement and heart rate – all these things are especially important when it comes to our health, all this data can then be transmitted wirelessly.
