ADVERSARIAL MACHINE LEARNING AGAINST VOICE ASSISTANT SYSTEMS

OBJECTIVE

June 1st, 2020 - July 30th, 2020

This project aims to study the security of voice assistance systems under adversarial machine learning. The audio adversarial samples generated by adversarial learning algorithms can be played via a loudspeaker and recorded with the microphone of voice assistance systems so as to fool the machine learning models in the system. To make the adversarial samples robust under audio propagation, the room impulse response needs to be estimated and used in the adversarial sample generation process. Specifically, the room impulse response and adversarial attack scenarios can be conducted in digital domain or simulated for the over-the-air scenarios using Python or Matlab.
