Date of joining:



Communication and Computer Engineering


Dr. Priyanka Gupta is an Assistant Professor in the Department of CCE at LNMIIT, Jaipur, since January 01, 2024. She earned her Ph.D. from DA-IICT, Gujarat in 2023. Her primary research is focused on anti-spoofing for voice biometric systems.


Dr. Priyanka Gupta has worked in the specialized areas of feature designing for spoofed speech and voice liveness detection, design of voice privacy systems, and the attacker's perspective. She has also contributed to the areas of pathological infant cry detection and dysarthric severity-level classification from speech. Till now, she has authored 24 research publications, comprising 3 SCI-journals (out of which 2 are indexed under Scopus Q1-top 10 journals), 15 international conferences, and 6 book chapters. She was the finalist for the best student paper award at SPCOM 2022 at IISc Bengaluru, for her paper titled 'Morse Wavelet Features for Pop Noise Detection', and was the session chair for one of the sessions in EUSIPCO 2022. She is also a reviewer for reputed conferences and journals such as ICASSP 2023, and EURASIP Journal on Audio, Speech, and Music Processing. Currently, she is working towards audio deepfake detection and has interest in related problems in speech and music applications.

Research Area

Anti-spoofing for voice biometric systems, voice liveness detection, time-frequency representations of speech signals, Automatic Speech Recognition (ASR) systems, feature engineering for machine learning and deep learning methods for various applications in speech and audio technologies
