TOWARD PRIVATE, SECURE, AND ROBUST AI-ENABLED VOICE SERVICES

By: Hanqing Guo

Advisor: Dr. Li Xiao

Voice, as a primary way for people to communicate with each other and interact with computers/smart devices, is expected to be secure and private when people use it. However, recent studies demonstrated the vulnerabilities of using voice to talk with people; conduct speaker authentication and deliver messages to smart devices. For example, the eavesdropper can record the conversation; the adversary can playback the speaker’s sound to attack the speaker authentication model; the hacker can craft fake speech to damage the reputation of the victim or launch impersonation scam; furthermore, the attacker can perform an adversarial voice attack to control the victim’s smart devices. This talk aims to understand the root cause of the vulnerabilities, address the challenges of achieving private and secure voice communication, and explore future directions to completely resolve the security concerns of the AI-enabled voice models and systems.
