Speech Watermarking for Security Applications

This poject explores security enhanced speaker verification and identification systems based on speech signal watermarking. The goal is to detect several situations where a playback speech, a synthetically generated speech, a manipulated speech signal or a hacker trying to imitate the speech is fooling the biometric system. One issue is to determine whether biometrics (i.e. speaker analysis) and watermarking can coexist simultaneously minimizing the mutual effects.
