Abstract: Highlights•Novel stand-alone Phonocardiography (PCG)-based psychological stress detection.•Identification of most discriminative PCG frequency bands for stress detection.•Generalizable gender-inclusive framework using deep wavelet scattering network for computation of feature space.•Cost-effective, easy signal acuisition makes framework suitable for homecare, rural areas and developing economies.
