+            
+            - **Model:** [sudoping01/maliba-asr-v1](https://huggingface.co/sudoping01/maliba-asr-v1)
+            - **Developer:** MALIBA-AI
+            - **Language:** Bambara (bm)
+            - **Task:** Automatic Speech Recognition (ASR)
+            - **Sample Rate:** 16kHz (automatically resampled)
+            
+            ## 🚀 How to Use
+            
+            1. **Record Audio:** Click the microphone button and speak in Bambara
+            2. **Upload File:** Click the upload button to select an audio file
+            3. **Transcribe:** Click the "Transcribe Audio" button
+            4. **View Results:** See your transcribed text in Bambara
+            
+            ## 📊 Performance Notes
+            
+            - Best results with clear speech and minimal background noise
+            - Supports various audio formats and durations
+            - Optimized for Bambara language patterns and phonetics
