From Sound Representation to Model Robustness

27 Jul 2020Mohammad EsmaeilpourPatrick CardinalAlessandro Lameiras Koerich

In this paper, we demonstrate the extreme vulnerability of a residual deep neural network architecture (ResNet-18) against adversarial attacks in time-frequency representations of audio signals. We evaluate MFCC, short time Fourier transform (STFT), and discrete wavelet transform (DWT) to modulate environmental sound signals in 2D representation spaces... (read more)
