The Biometric group at Idiap Research Institute is releasing AVspoof, a free spoofing database for automatic speaker verification (ASV).

AVspoof is intended to provide stable, non-biased spoofing attacks for researchers to test both their ASV systems and anti-spoofing algorithms.

Ten attacks are created based on newly acquired audio recordings.

The database includes 44 speakers, each participating in four sessions with different environmental conditions and setups.

After data acquisition, the attacks, namely replay, voice conversion and speech synthesis attacks were generated.
