Training and evaluating speech models that must handle real Catalan speech:

- 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 Catalan. Read more in our guide to conversational vs. scripted speech data.

Frequently asked questions
What does the Catalan speech dataset include?
500 hours of spontaneous two-person conversations from 50 vetted native speakers recorded in Spain, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Catalan hard for speech recognition?
Most Catalan speakers also speak Spanish and switch between the two, so a model has to tell them apart word by word. Catalan has sounds Spanish lacks, like the neutral vowel and open "e" and "o", and Barcelona, Valencian and Balearic speech differ.
Is there free Catalan speech data?
Yes, ParlamentParla, Mozilla Common Voice and FLEURS are free for commercial use. This dataset is spontaneous two-person conversation recorded in Spain, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Catalan 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 Catalan speech dataset cost?
Pricing is $75 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.
