Abstract :
In this paper, we have proposed vocalization of heart rate variability (HRV) as a perceptual analysis tool. We adapted a phonation-production model to encode external signals and generate audible representations of them. HRV changes, caused by induced perturbations to the autonomous nervous system, could be perceived on vocalized HRV.
