title: Novel Speech Features for Improved Detection of Spoofing Attacks
summary: Now-a-days, speech-based biometric systems such as automatic speaker
verification (ASV) are highly prone to spoofing attacks by an imposture. With
recent development in various voice conversion (VC) and speech synthesis (SS)
algorithms, these spoofing attacks can pose a serious potential threat to the
current state-of-the-art ASV systems. To impede such attacks and enhance the
security of the ASV systems, the development of efficient anti-spoofing
algorithms is essential that can differentiate synthetic or converted speech
from natural or human speech. In this paper, we propose a set of novel speech
features for detecting spoofing attacks. The proposed features are computed
using alternative frequency-warping technique and formant-specific block
transformation of filter bank log energies. We have evaluated existing and
proposed features against several kinds of synthetic speech data from ASVspoof
2015 corpora. The results show that the proposed techniques outperform existing
approaches for various spoofing attack detection task. The techniques
investigated in this paper can also accurately classify natural and synthetic
speech as equal error rates (EERs) of 0% have been achieved.
