Linear Prediction Residual-Based Constant-Q Cepstral Coefficients for Replay Attack Detection

2020

This paper proposes a new linear prediction residual-based constant-Q cepstral coefficients (LPR-CQCC) feature for replay attack detection (RAD). The main contribution of the proposed feature is to modify conventional constant-Q cepstral coefficients (CQCC) using linear …
