Speech and communication are integral parts of human relationships and development. As such, researchers strive to understand the ways to enhance communication and improve speech. Here are a couple of studies that aim to improve communication using BIOPAC research tools…

Heart-to-heart: infant heart rate at 3 months is linked to infant-directed speech, mother–infant interaction, and later language outcomes. Frontiers in Human Neuroscience, 18, 1380075. Endevelt-Shapira, Y., Bosseler, A. N., Zhao, T. C., Mizrahi, J. C., Meltzoff, A. N., & Kuhl, P. K. (2024).

This study aimed to build on research that supports infant-directed speech (IDS) during one-on-one interactions with a parent as helping develop language later on. Researchers hypothesized that infants’ attention during these interactions would further support language development. In order to determine attention, they recorded the heartbeat of infants during IDS one-on-one interactions with a parent.

Respiration-enhanced Human-Robot Communication. In Companion of the 2024 ACM/IEEE International Conference on Human-Robot Interaction (pp. 813-816). Obi, T., & Funakoshi, K. (2024, March).

Researchers studied the use of respiration information to help robots communicate more seamlessly with people. They developed a robot that performs pseudo-respiration and uses human respiratory patterns to navigate interactions and prevent overlapping speech. Researchers utilized a BIOPAC respiratory transducer to determine the human respiratory patterns.

Acoustic and prosodic speech features reflect physiological stress but not isolated negative affect: a multi-paradigm study on psychosocial stressors. Scientific Reports, 14(1), 5515. Kappen, M., Vanhollebeke, G., Van Der Donckt, J., Van Hoecke, S., & Vanderhasselt, M. A. (2024).

This study examined speech features in two different stress paradigms to better understand the role that speech plays in stress research. Researchers recorded speech as it is used in daily life as a way to record stress unobtrusively. EDA and ECG were recorded while participants completed both stress and control verbal tasks.
