Voice spoofing é uma estratégia genérica utilizada para burlar sistemas de autenticação biométrica baseados em identificação por voz. Dentre as diversas possibilidades específicas, os ataques do tipo playback speech são ...

In this work, a voice anti-spoofing dataset was built from samples in Latin America Spanish implementing voice conversion and text-to-speech algorithms and later a test was performed on anti-spoofing models trained on ...

Although voice biometrics has been at the forefront of speech technologies, spoofing attacks have been one of the main issues responsible for avoiding its practical usage in commercial applications. Consequently, this ...

Os avanços tecnológicos têm possibilitado cada vez mais a busca e a disseminação de informações e, com isso, o volume de dados gerados cresce extraordinariamente. Outro fator que contribui para este crescimento é o uso de ...

In this work, are proposed two models that are able to detect replay spoofing attacks on Automa tic Speaker Verication (ASV). The models consists on a k-Nearest Neighbour (k-NN) classifier and Support Vector Machine (SVM) ...

In the scope of voice biometrics, the term replay attack, (RA) refers to the dishonest attempt made by an impostor to spoof someone else's identity by replaying the subject's previously recorded speech close to the Automatic ...
