Audio adversarial attack; Replay attack; Speech processing system anti-spoofing
With the fast-growing number of users and usage scenarios, the security problem of speech processing systems (e.g., speaker verification systems, intelligent personal assistant systems) becomes a new concern. Recent work has found that speech processing systems are vulnerable to multiple types of attacks such as replay attack, audio adversarial attack, and ultrasound attack. For example, a small but carefully designed noise, when added to a normal speech signal, can make automatic speech recognition systems produce arbitrary wrong transcriptions. These attacks are demonstrated to be extremely threatening in experimental and realistic settings, even worse, the attacker can easily bypass conventional defense models by doing an adversarial drift. Therefore, we focus on study a robust and universal defense strategy that is able to protect the speech processing system from a set of attacking technologies and their variants.
