High Fidelity Audio Playback Attack Forensics Algorithm and Aimulation
CAO Hui
Abstract：ABSTRACT:Aiming at the playback attack in the speech certification system,In the study of the playback attack forensics,Model is presented based on the channel noise and playback voice MFCC feature parameter extraction of forensics algorithm ,Through the labview software programming for simulation,Extract the suspected playback attack speech and original speech channel noise difference spectrum and suspected playback speech MFCC fea?ture values,Results show that by extracting playback speech mode noise in channel and MFCC feature parame?ters and design filter denoising to identify original speech differences and high-fidelity recording ,For voice judi?cial authentication and voice provides theory basis for the design of the authentication system.
