Constant Q Cepstral coefficients for classification of normal vs. Pathological infant cry

ICASSP 2022accepted

Classification of normal vs. pathological infant cry is an interesting and technologically challenging research problem due to quasi-periodic sampling of vocal tract spectrum by high pitch-source harmonics resulting in extremely poor spectral resolution for commonly used spectral features, such as M…

Cross-Teager Energy Cepstral Coefficients for Replay Spoof Detection on Voice Assistants

ICASSP 2021accepted

Voice assistants (VAs) are highly vulnerable to replay attacks, where the impostor plays pre-recorded voice samples to gain an unauthorized access to personalised devices. To that effect, we present an optimal microphone-channel selection scheme using Cross-Teager Energy Operator (CTEO) for spoofed…
