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

FAQ
Frequently asked questions
What does the Spanish (European) speech dataset include?
1,000 hours of spontaneous two-person conversations from 100 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 European Spanish hard for speech recognition?
Most of Spain separates the "z" and soft "c" sound from "s", uses "vosotros" and has its own everyday vocabulary, so it sounds and reads differently from Latin American Spanish. Regional accents add more: Andalusian speakers often drop or aspirate a final "s". A model needs to hear these to transcribe Spanish speakers accurately.
Is there free European Spanish speech data?
Yes, Multilingual LibriSpeech Spanish and Mozilla Common Voice Spanish are free for commercial use. VoxPopuli Spanish has unclear terms. 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 Spanish (European) 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.
