Built for
Training and evaluating speech models that must handle real Hungarian speech:
- Automatic speech recognition (ASR / STT)

- Voice agents and IVR for Hungary
- 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 Hungarian. Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the Hungarian speech dataset include?
1,000 hours of spontaneous two-person conversations from 100 vetted native speakers recorded in Hungary, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Hungarian hard for speech recognition?
Hungarian isn't Indo-European. It builds words by stacking suffixes, so one root can produce hundreds of forms, and vowel harmony changes those suffixes. Vowel length changes meaning too ("kor" is age, "kór" is disease), and a model has to hear it correctly.
Is there free Hungarian speech data?
Yes, Mozilla Common Voice and FLEURS are free for commercial use. VoxPopuli has unclear terms. This dataset is spontaneous two-person conversation recorded in Hungary, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Hungarian 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 Hungarian speech dataset cost?
Pricing is $90 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.
