Novel Spectral Root Cepstral Features for Replay Spoof Detection
Asia-Pacific Signal and Information Processing Association Annual Summit and Conference, pp. 1945.0-1950, 2018.
Replay poses a greater threat to the Automatic Speaker Verification (ASV) system than any other spoofing attacks, as it neither require any specific expertise nor a sophisticated equipment.
