Do you trust your data? A Journey through Adversarial and Poisoning Attacks and Defenses on Speech Systems.

June 25, 2024

Talk, ETS Seminar, 06-2024, Montreal, Canada

Abstract: As the prevalence of voice-controlled devices and speech systems continues to grow, so too does the importance of ensuring their security and reliability. However, these systems are increasingly vulnerable to adversarial and poisoning attacks, which can exploit vulnerabilities and compromise their performance. In this talk, we delve into the intricate landscape of adversarial attacks targeting speech systems, presenting our research on detecting and classifying these attacks to better understand their nuances and impact. Furthermore, we discuss the creation of dirty and clean label poisoning attacks, where maliciously crafted data is injected into training datasets, and explore their implications on system integrity. We also examine a range of defenses designed to mitigate the effects of poisoning attacks, aiming to increase the resilience of speech recognition systems against such threats.

Adversarial and Poisoning attacks against speech systems: where to find them?

Talk, CLSP Seminar, 01-2024, Baltimore, Maryland

Abstract: The majority of today’s machine learning algorithms share common foundations and core concepts, rendering them susceptible to various attacks. In this short talk, I would like to dive into the world of adversarial attacks and poisoning attacks on speech systems. What are they, how dangerous are they, and what can be done against them?

An Introduction to Voice Conversion

June 22, 2022

Talk, JSALT Summer School 2022, CLSP, Baltimore, Maryland

I gave an 1h15 talk about the bases of Voice Conversion, which was then followed by a 3h competitive lab on antispoofing techniques against various voice conversion and TTS systems, co-animated by Thibault Gaudier and Valentin Pelloin. This talk was targetting PhD student and grad students.
