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.

Abstract: A method and device for detecting an audio adversarial attack with respect to a voice command processed by an automatic speech recognition system is described.

Abstract: Apparatus (300, 400) and method (600) for passive remote control are provided. The apparatus (300) includes at least two radio-frequency identification (RFID) tag devices (330_1, 330_2, 330_N, 430_1, 430_2) each operable to transmit a signal when activated and a first switch coupled to the at least two RFID tag devices (310_1, 310_2, 310_K, 410_1) and operable to activate the at least two RFID tag devices when the first switch is in a first switch state, said first switch being a first key identified by RFID tag information of the at least two RFID tag devices. Apparatus (110) and method (700) for receiving RFID signals are also provided.
