The objective of the Spoofing and Anti-Spoofing (SAS) corpus is a standard spoofing database for both spoofing and anti-spoofing (also known as countermeasure) research. The SAS corpus will include three forms of spoofing: speech synthesis, voice conversion and replay. In each form of spoofing, multiple state-of-the-art techniques will be employed to generate the spoofing materials. For example in speech synthesis, statistical parametric and unit selection techniques will be used.
