                 This is a demo for JASR, pronounced <i>Jasir</i>, an automatic speech recognition system optimized for the regional dialects of <i>Jazirat al-Arab</i>, or the Arabian Peninsula. The model is a fine-tune of the speech foundation model <a href="https://huggingface.co/facebook/w2v-bert-2.0" style="color: #FF5349;">w2v-BERT 2.0</a>, a 580M pre-trained speech encoder.

                Simply <strong>upload an audio file</strong> 📤 or <strong>record yourself speaking</strong> 🎙️⏺️ to try out the model!
