Arbitrary Discrete Fourier Analysis and Its Application in Replayed Speech Detection
In this paper, a group of finite sequences and its variants were proposed to use in conducting signal analysis; we called the developed signal analysis methods arbitrary discrete Fourier analysis (ADFA), Mel-scale discrete Fourier analysis (MDFA) and constant Q analysis (CQA).
A Study of Using Cepstrogram for Countermeasure Against Replay Attacks
This study investigated the cepstrogram properties and demonstrated their effectiveness as powerful countermeasures against replay attacks.
Speech Enhancement Based on Reducing the Detail Portion of Speech Spectrograms in Modulation Domain via Discrete Wavelet Transform
The presented DWT-based SE method with various scaling factors for the detail part is evaluated with a subset of Aurora-2 database, and the PESQ metric is used to indicate the quality of processed speech signals.
