+# XTTS-v2 Model Mirror for Quantum Sync
+
+This is a mirror/backup of the **Coqui XTTS-v2** model for use with the [Quantum Sync](https://github.com/Useforclaude/quantum-sync-v5) project.
+
+## 🎯 Purpose
+
+This mirror serves as:
+- **Backup** in case the original model becomes unavailable
+- **Faster access** for Quantum Sync users
+- **Stable reference** for production deployments
+
+## 📋 Model Information
+
+**Original Model:** [coqui/XTTS-v2](https://huggingface.co/coqui/XTTS-v2)
+
+**Architecture:** XTTS-v2 (Zero-shot multi-lingual TTS)
+
+**Model Size:** ~1.87 GB
+
+**Supported Languages:** 13 languages
+- English (en)

+  --tts-language en
+```
+
+### Direct Usage with TTS Library
+
+```python
+from TTS.api import TTS
+
+# Use this mirror
+tts = TTS(model_name="useclaude/quantum-sync-xtts-v2")
+
+# Generate speech
+tts.tts_to_file(
+    text="Hello, this is a test.",
+    speaker_wav="reference_voice.wav",
+    language="en",
+    file_path="output.wav"
+)
+```
+
+### Voice Cloning Example
+
+```python
+from TTS.api import TTS
+
+# Initialize
+tts = TTS(model_name="useclaude/quantum-sync-xtts-v2")
+
+# Clone voice from reference audio (6-30 seconds)
+tts.tts_to_file(
+    text="The quick brown fox jumps over the lazy dog.",
+    speaker_wav="my_voice_sample.wav",  # Your voice reference
+    language="en",
+    file_path="output_cloned.wav"
+)
+```
+
+## 📊 Performance
+
+**From Quantum Sync Production Tests (2025-10-13):**
+
+| Metric | Value |
+|--------|-------|
+| **Synthesis Speed** | ~3.7 segments/minute |
+| **Processing Time** | 17 min for 277 segments (23 min audio) |
+| **Duration Accuracy** | ~87% audio, ~13% silence gaps |
+| **Timeline Drift** | -1.7% (excellent) |
+| **Voice Quality** | 8/10 |
+| **Cloning Accuracy** | Excellent |
+| **VRAM Usage** | 6-8 GB |
+
+**Comparison:**
+- **XTTS-v2**: 15-17 min, 8/10 quality, FREE, 87% audio
+- **F5-TTS**: 20-25 min, 7/10 quality, FREE, 55% audio
+- **AWS Polly**: 5 min, 9/10 quality, ~$0.06, no cloning
+
+## 🎛️ Advanced Parameters
+
+```python
+# Speed control (0.5 - 2.0)
+tts.tts_to_file(
+    text="Hello world",
+    speaker_wav="voice.wav",
+    language="en",
+    speed=0.8,  # Slower speech
+    file_path="output.wav"
+)
+
+# Temperature control (0.1 - 1.0)
+tts.tts_to_file(
+    text="Hello world",
+    speaker_wav="voice.wav",
+    language="en",
+    temperature=0.75,  # More expressive
+    file_path="output.wav"
+)
+```
