+# Piper TTS Server (Local Text-to-Speech)
+
+This repository contains scripts to generate high-quality Neural TTS audio using **Piper** and stream it directly to **Snapcast** for multi-room audio announcements.
+
+## ⚡ Functionality
+
+The primary script `speak_direct.sh` performs the following pipeline:
+1.  **Input:** Text string, Voice Model, Speed.
+2.  **Generation:** Calls the `piper` binary to generate a `.wav` file locally.
+3.  **Processing:** Uses `sox` to resample audio to 48kHz Stereo (matching Snapserver).
+4.  **Playback:** Pipes raw audio data directly to the Snapserver TCP stream (`/tmp/snapfifo` or TCP Port).
+
+## 📂 File Manifest
+
+*   **`speak_direct.sh`**: Main entry point called by Home Assistant via SSH.
+    *   Usage: `./speak_direct.sh "Text to speak" "model_name.onnx" "1.0"`
+*   **`test_snapcast.sh`**: Debug tool to verify the Snapcast pipe connection (generates a sine wave).
+*   **`play_wav_to_snapcast.sh`**: Helper utility to stream existing WAV files to the speakers.
+
+## 🛠️ Integration with Home Assistant
+
+Home Assistant triggers these scripts using a `shell_command` over SSH.
+
+**Home Assistant YAML:**
+```yaml
+shell_command:
+  tts_direct_piper: >
+    ssh -i /config/ssh/id_rsa -o StrictHostKeyChecking=no user@192.168.20.13 
+    '/home/user/speech_piper/speak_direct.sh "{{ text }}" "{{ voice }}" "{{ speed }}"'
+```
+
+## 📦 Models
+
+Voices are stored in the `/data` directory (ignored by Git due to size).
+Required files for each voice:
+1.  `voice_name.onnx` (Binary model)
+2.  `voice_name.onnx.json` (Config file)
+
+**Common Voices:**
+*   `en_US-hal_6409-medium` (HAL 9000 style)
+*   `en_US-trump-medium` (Danny - Parody)
+*   `en_US-picard_7399-medium` (Picard)
