+# Blaze STT Extension for TEN Framework
+
+Blaze Speech-to-Text (STT) extension for [TEN Framework](https://github.com/TEN-framework/ten-framework).
+
+## Installation
+
+```bash
+pip install -r requirements.txt
+```
+
+Or install dependencies directly:
+
+```bash
+pip install httpx pydantic
+```
+
+## Configuration
+
+### Environment Variables
+
+Set the following environment variables:
+
+```bash
+export BLAZE_STT_API_URL="http://localhost:8000"
+export BLAZE_STT_API_KEY="your-api-key-here"  # Optional
+```
+
+### Property.json (TEN Framework)
+
+The extension includes a `property.json` file with default configuration that TEN framework can use:
+
+```json
+{
+    "params": {
+        "api_url": "${env:BLAZE_STT_API_URL}",
+        "api_key": "${env:BLAZE_STT_API_KEY}",
+        "language": "vi",
+        "enable_segments": false,
+        "enable_refinement": false,
+        "timeout": 3600
+    }
+}
+```
+
+TEN framework will automatically read this file and use environment variables for configuration.
+
+## Usage
+
+### As TEN Framework Extension
+
+```python
+from blaze_stt_python import BlazeSTTExtension
+
+# Initialize extension (can accept dict config from TEN framework)
+stt = BlazeSTTExtension(config={
+    "api_url": "http://localhost:8000",
+    "api_key": "your-api-key",
+    "language": "vi",
+})
+
+# Process audio using TEN framework interface
+result = stt.process({
+    "audio_data": audio_bytes,
+    "audio_content_type": "audio/wav",
+    "language": "vi",
+})
+
+print(result["transcription"])
+
+# Get extension metadata
+metadata = stt.get_metadata()
+print(metadata)
+```
+
+### As Direct Extension
+
+```python
+from blaze_stt_python import BlazeSTTExtension, BlazeSTTConfig
+
+# Initialize extension
+config = BlazeSTTConfig(
+    api_url="http://localhost:8000",
+    api_key="your-api-key",
+    default_language="vi",
+)
+stt = BlazeSTTExtension(config=config)
+
+# Transcribe audio
+result = stt.transcribe(
+    audio_data=audio_bytes,
+    audio_content_type="audio/wav",
+    language="vi",
+)
+
+print(result["transcription"])
+```
