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 Arabic (Darija). Read more in our guide to conversational vs. scripted speech data.

FAQ
Frequently asked questions
What does the Arabic (Darija) speech dataset include?
1,500 hours of spontaneous two-person conversations from 150 vetted native speakers recorded in Morocco, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Moroccan Darija hard for speech recognition?
Moroccan Darija is hard even for speakers of other Arabic dialects to follow. It drops many short vowels, borrows from Amazigh, French and Spanish, and is often written online in Latin letters and numbers. Data in MSA or Middle Eastern Arabic does little for a Darija model.
Is there free Moroccan Darija speech data?
Yes, DVoice is free for commercial use. MGB-5 Moroccan Dialect needs a paid license. This dataset is spontaneous two-person conversation recorded in Morocco, with speaker metadata, one channel per speaker and signed commercial-use consent.
Can I use this Arabic (Darija) 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.
