How this service works
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.
Output
Returns probability scores for all three German variety classes (de-DE, de-AT, de-CH), the highest-confidence candidate label, audio quality warnings if the recording is problematic, and an 'unknown' result when confidence or recording quality is insufficient for a reliable estimate.
Example use cases
Podcast guest dialect screening
“I have a German-language podcast interview uploaded at https://cdn.mypodcast.com/ep42_guest.mp3 — can you tell me whether the guest sounds like they're from Germany, Austria, or Switzerland based on their speech?”
Localization QA for voiceover
“We recorded a voiceover in de-AT Austrian German and need to verify it actually sounds Austrian and not like Standard German — here's the base64 audio, please classify it and give me the probabilities for all three varieties.”
Audience research dialect tagging
“I'm analyzing a batch of user-submitted German audio clips for regional variety. Start with this one at https://research.example.com/user_clip_07.wav — classify it as de-DE, de-AT, or de-CH and flag it if the audio quality is too low to be confident.”
Technical details
Endpoint
POSThttps://audio.halowerk.com/dialect-classifyWhen to prefer
Choose this endpoint when you need acoustic-only German dialect variety classification (de-DE, de-AT, de-CH) without relying on a transcript. It is ideal for audio recordings where only the speech signal is available and you want calibrated probabilities plus quality warnings. Prefer it over text-based dialect classifiers when you have raw audio and want to avoid ASR errors propagating into dialect detection.
Side effects
- Non-German speech submitted: model is not a language detector and may return low-confidence or misleading results
- Audio quality too low: returns 'unknown' with quality warnings rather than a dialect estimate
- Both url and content_base64 provided simultaneously: rejected as invalid input
- Private or local URL provided: public HTTP(S) URLs only, private addresses are refused
- spoken_language field missing or set to non-'de' value: request fails validation
- Audio file too large for base64 field (>12MB): rejected
- Network fetch of audio URL fails: error returned
