Built for
Training and evaluating speech models that must handle real Danish speech:
- Automatic speech recognition (ASR / STT)
- Text-to-speech & voice synthesis prosody
- Voice agents and IVR for Denmark
- Speaker diarization & turn-taking models
- Speech LLM / audio-understanding fine-tuning
Why conversational data?
Models trained on read speech consistently underperform on spontaneous audio. Disfluencies, overlap, and natural speech rates aren’t in the training distribution. This dataset closes that gap for Danish. Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the Danish speech dataset include?
500 hours of spontaneous two-person conversations from 50 vetted native speakers recorded in Denmark, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Danish hard for speech recognition?
Danish is notoriously hard for speech recognition. Consonants soften or vanish, vowels blur together, and the stød, a creaky catch in the voice, changes meaning. What people say often sounds far from the spelling, so models need a lot of real conversational audio.
Is there free Danish speech data?
Yes, the NST Danish ASR Database, Mozilla Common Voice and FLEURS are free for commercial use, and CoRal is too, with restrictions. This dataset is spontaneous two-person conversation recorded in Denmark, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Danish dataset commercially?
Yes. The dataset is licensed for commercial use, including training ASR, TTS, and other voice-AI models. Every speaker has signed explicit commercial-use consent, and we provide the full consent chain for your legal review.
How much does the Danish speech dataset cost?
Pricing is $95 per hour of audio. Volume discounts are available for full-dataset and multi-language purchases. Contact us for a quote.
Can I evaluate samples before buying?
Yes. Request samples with your company email, and we'll email you representative audio files and matching transcripts so your team can audit quality before committing.
