Catalan conversational speech dataset

500 hours of unscripted Catalan conversation between pairs of native speakers, 50 vetted speakers in all, recorded in Spain. Every recording is dual-channel, one speaker per channel, and comes with a time-aligned, human-verified transcript, speaker metadata (age, gender, region and recording device) and signed consent records, under a commercial license for ASR, TTS and voice AI training.

Built for

For teams training or testing speech models that have to cope with real Catalan speech:

  • Automatic speech recognition (ASR / STT)
  • Text-to-speech and voice synthesis prosody
  • Voice agents and IVR for Spain
  • Speaker diarization and turn-taking models
  • Speech LLM and audio-understanding fine-tuning

Why conversational data?

Models trained on read speech lose accuracy on spontaneous audio, because hesitations, overlapping turns and natural speaking rates never made it into their training data. This dataset fills that gap for Catalan. Our guide to conversational speech data explains why it matters.

FAQ

Frequently asked questions

What is in the Catalan speech dataset?

500 hours of unscripted conversation between pairs of native speakers, 50 vetted speakers in all, recorded in Spain. Each conversation is delivered as dual-channel audio with a time-aligned transcript, speaker metadata (age, gender, region and recording device) and the consent records behind it.

What makes Catalan hard for speech recognition?

Nearly every Catalan speaker also speaks Spanish and switches between the two, so a model must separate them word by word. It has sounds missing from Spanish, including the neutral vowel and an open "e" and "o", and speech from Barcelona, Valencia and the Balearics differs.

Is the Catalan dataset licensed for commercial use?

Yes. The license covers commercial training and evaluation of ASR, TTS and other voice AI models. Every speaker signed explicit consent to commercial use, and Spirelight shares the full consent records for your legal review.

What does the Catalan speech dataset cost?

$75 per hour of audio. Buying the full dataset, or several languages together, qualifies for a volume discount: ask for a quote.

Can I check samples before I buy?

Yes. Request samples on this page and the Spirelight team emails representative audio, matching transcripts and the metadata schema within 48 hours, so your team can audit the data before committing.
