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

FAQ
Frequently asked questions
What does the Arabic (Levantine) speech dataset include?
500 hours of spontaneous two-person conversations from 50 vetted native speakers recorded in Lebanon, delivered as dual-channel audio with time-aligned transcripts, speaker metadata (age, gender, region, device), and consent documentation.
What makes Levantine Arabic hard for speech recognition?
Levantine Arabic, spoken in Lebanon, Syria, Jordan and Palestine, turns "q" into a glottal stop in the cities and has its own vocabulary and verb forms. Lebanese speakers also switch into French and English mid-sentence, so a model can face three languages in one conversation.

Can I use this Arabic (Levantine) 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.
