When the Differences in Frequency Domain are Compensated: Understanding and Defeating Modulated Replay Attacks on Automatic Speech Recognition [article]

Shu Wang, Jiahao Cao, Xu He, Kun Sun, Qi Li
2020 pre-print
Automatic speech recognition (ASR) systems have been widely deployed in modern smart devices to provide convenient and diverse voice-controlled services.  ...  Therefore, by jointly checking suspicious features in both frequency and time domains, DualGuard can successfully detect various replay attacks including the modulated replay attacks.  ...  Jiahao Cao and Qi Li are the corresponding authors of this paper.  ...
