Built for
Training and evaluating speech models that must handle real Swedish speech:
- Automatic speech recognition (ASR / STT)
- Text-to-speech & voice synthesis prosody
- Voice agents and IVR for Sweden
- 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 Swedish. Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the Swedish speech dataset include?
500 hours of spontaneous two-person conversations from 50 vetted native speakers recorded in Sweden, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Swedish hard for speech recognition?
Swedish has a pitch accent that separates words spelled the same, like "anden" (the duck) and "anden" (the spirit), a famously tricky "sj" sound and many vowel qualities. Accents from Skåne to Norrland differ a lot, and casual speech drops endings the written form keeps.
Is there free Swedish speech data?
Yes, the NST Swedish ASR Database, RixVox, Mozilla Common Voice and FLEURS are free for commercial use. This dataset is spontaneous two-person conversation recorded in Sweden, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Swedish 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 Swedish 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.
