Abstract
A method and device is described and includes: obtaining an input audio signal associated with the voice input, obtaining a transcript resulting from the processing of the input audio signal, converting the transcript into a synthesized audio signal; extracting an acoustic feature of a same type from the input audio signal and synthesized audio signal, delivering a first sequence of features vectors associated with the input audio signal and a second sequence of features vectors associated with the synthesized audio signal converting the acoustic features to corresponding acoustic features associated with a target reference voice, delivering a first sequence and a second sequence of converted features vectors computing a dynamic time warping distance between the first sequence and second sequence of converted features vectors, and delivering data representative of a detection of an audio adversarial attack, as a result of a comparison between the dynamic time warping distance and a predetermined threshold.
