Classifies only three broad German-language varieties
Classifies only three broad German-language varieties: de-DE Germany German, de-AT Austrian German and de-CH Swiss German. The model works on acoustic speech embeddings and does not read a transcript. It returns probabilities for all three classes, the strongest candidate, audio quality warnings and unknown whenever confidence or recording quality is insufficient. The result is a statistical variety estimate, not a statement about a speaker's origin, identity, nationality or place of residence.
