+# 🎤 Wakanda Whisper - Kinyarwanda ASR
+
+A state-of-the-art automatic speech recognition system specifically fine-tuned for Kinyarwanda language, built on OpenAI's Whisper architecture.
+
+## 🌟 Features
+
+- **High Accuracy**: Fine-tuned specifically for Kinyarwanda speech patterns
+- **Multiple Input Methods**: Upload audio files or record directly through microphone
+- **Format Support**: Supports WAV, MP3, M4A, FLAC, and other common audio formats
+- **Real-time Processing**: Fast inference with optimized performance
+- **User-friendly Interface**: Beautiful and intuitive web interface
+
+## 🚀 Model Details
+
+- **Base Architecture**: OpenAI Whisper Small
+- **Language**: Kinyarwanda (rw)
+- **Parameters**: ~39M
+- **Training Data**: Curated Kinyarwanda speech dataset
+- **Model Repository**: [WakandaAI/wakanda-whisper-small-rw-v1](https://huggingface.co/WakandaAI/wakanda-whisper-small-rw-v1)
+
+## 🎯 How to Use
+
+### Option 1: Upload Audio File
+1. Click on the "Upload Audio File" tab
+2. Select your Kinyarwanda audio file
+3. Click "Transcribe Audio" to get the text
+
+### Option 2: Record Audio
+1. Click on the "Record Audio" tab
+2. Click the microphone button to start recording
+3. Speak in Kinyarwanda
+4. Stop recording and click "Transcribe Recording"
+
+## 📊 Performance
+
+This model has been optimized for:
+- Clear speech recognition in various acoustic conditions
+- Multiple Kinyarwanda dialects and accents
+- Noise robustness for real-world audio
+- Fast processing suitable for real-time applications
+
+## 🤝 About WakandaAI
+
+WakandaAI is dedicated to advancing AI technologies for African languages and communities. This project is part of our mission to make speech recognition accessible in Kinyarwanda.
+
