Training and evaluating speech models that must handle real Dutch (Surinamese) speech:
- Automatic speech recognition (ASR / STT)

- 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 Dutch (Surinamese). Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the Dutch (Surinamese) speech dataset include?
1,000 hours of spontaneous two-person conversations from 100 vetted native speakers recorded in Suriname, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Surinamese Dutch hard for speech recognition?
Surinamese Dutch has its own pronunciation and vocabulary and lives alongside Sranan Tongo, Sarnami Hindustani, Javanese and English. Speakers switch between them in the same conversation, so a model trained only on Dutch from the Netherlands misses a lot.
Is there free Surinamese Dutch speech data?
None specific to Suriname, but Mozilla Common Voice Dutch is free for commercial use, and Corpus Gesproken Nederlands is too, with restrictions. This dataset is spontaneous two-person conversation recorded in Suriname, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Dutch (Surinamese) 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 Dutch (Surinamese) speech dataset cost?
Pricing is $65 per hour of audio. Volume discounts are available for full-dataset and multi-language purchases. Contact us for a quote.
