Session Description:

Automatic speaker verification (ASV) systems have witnessed major breakthrough in the past decade and have led to many real-world practical systems. These systems are vulnerable to spoofing attacks and detection of such attacks has gained attention in the recent years [1, 2]. We believe apart from studying robust countermeasures, it is worth studying the weak aspects of ASV systems in order to make them robust against various kinds of attacks. In order to know the loopholes of the ASV systems, one needs to understand the scope of various attacks from the perspective of the attacker to deceive the systems. Such investigations and findings can lead to develop robust ASV systems for high security applications. With this special session, we plan to explore the attacker perspective on ASV that will in turn provide insights towards improving the robustness of futuristic ASV systems.

The conventional technical sessions in speaker recognition that are part of Interspeech mainly focuses to improve the ASV system performance under various adverse conditions using latest available standard corpora. Again, there are sessions on anti-spoofing and special session ASVspoof challenge series that are held biannually that are based on studying novel countermeasures for detection of spoofing attacks. In contrast to these exiting sessions, this special session will devote to find out the weak spots of existing ASV systems from the attacker’s perspective. For an attacker, the best way is to attack using the knowledge from the ASV system itself. There are three different possibilities to perform attacks using such information that are well studied in the literature of machine learning [3-8]. In addition, attacks to various spoofing countermeasures are also possible [9]. We would like explore different possible attacks to ASV and spoofing countermeasures that will showcase the weak aspects of existing systems, which can be worked upon to safeguard from such attacks.

We expect contributions from researchers from ASV as well as different fields of machine learning for this special session submission that we plan to have as an oral session presentations followed by a discussion. The prospective submissions can use any standard corpus available for ASV or spoofing countermeasures for the studies related to this session. The objective of the studies may focus on degrading the performance of existing systems by various possible attacks to highlight the loopholes in the system.

The topics are as follows but not limited to:

1/ To study the loopholes of ASV systems from attacker's perspective

2/ Increasing the vulnerability of ASV to various spoofing attacks for unauthorized access

(i) Voice Conversion (ii) Text-to-speech (iii) Replay (iv) Impersonation

3/ Adversarial attacks: ASV systems to assist the spoofed speech. This may include black-box, grey-box, white-box or any such attacks

4/ Attacks on spoofing countermeasures (CM)

5/ Joint attacks on ASV and spoofing CM
