Replay spoofing attack detection using deep neural networks

2018

In recent years, there has been increased interest in speaker verification(SV) systems and their usage has become widespread. This situation made the detecting of spoofing attacks, the discrimination of genuine speech from spoofed speech, an …

An Experimental Study on Audio Replay Attack Detection Using Deep Neural Networks

2018

Automatic speaker verification (ASV) systems can be easily spoofed by previously recorded speech, synthesized speech and speech signal that artificially generated by voice conversion techniques. In order to increase the reliability of the ASV systems, …

ASVspoof 2015: the first automatic speaker verification spoofing and countermeasures challenge

2015

An increasing number of independent studies have con-firmed the vulnerability of automatic speaker verification (ASV) technology to spoofing. However, in comparison to that involving other biometric modalities, spoofing and countermea-sure research for ASV is still …
