Do generator artifacts survive a language change?
A language-disjoint study of forensic representations for speech deepfakes
Source tracing assumes a synthesis system leaves a trace that belongs to the system, not to the language it happens to be speaking. We test that by holding the generator fixed and replacing the language entirely: 62 generators learned across 12 languages, evaluated on 6 removed from the corpus before training.
