+# 🎙️ Chatterbox TTS - Google Colab Notebook
+
+[![Open In Colab](https://colab.research.google.com/assets/colab-badge.svg)](https://colab.research.google.com/github/viveksurmay/chatterbox-colab/blob/master/chatterbox_colab.ipynb)
+
+This repository contains a comprehensive Google Colab notebook for using **Chatterbox TTS** by [Resemble AI](https://resemble.ai) - a state-of-the-art open-source text-to-speech model.
+
+## 🌟 Features
+
+The notebook includes:
+
+- **🚀 Easy Setup**: One-click installation and model loading
+- **🎯 Basic TTS**: Simple text-to-speech with default voice
+- **🎭 Voice Cloning**: Upload audio samples to clone any voice
+- **🎛️ Interactive Controls**: Real-time parameter adjustment with widgets
+- **🔄 Voice Conversion**: Convert existing speech to different voices
+- **💾 File Downloads**: Save generated audio to your device
+- **🔍 Watermark Detection**: Verify responsible AI watermarking
+- **📝 Example Texts**: Pre-written samples for different scenarios
+
+## 🚀 Quick Start
+
+1. **Open in Colab**: Click the "Open in Colab" badge above
+2. **Enable GPU**: Go to Runtime → Change runtime type → Select GPU
+3. **Run All Cells**: Runtime → Run all (or run cells individually)
+4. **Upload Audio**: When prompted, upload audio files for voice cloning
+5. **Experiment**: Try different texts and parameter combinations
+
+## 🎛️ Parameters Explained
+
+### Exaggeration (0.25 - 2.0)
+- **0.5**: Neutral, natural speech
+- **0.7-1.0**: More expressive and emotional
+- **1.5+**: Highly dramatic (may be unstable)
+
+### CFG Weight (0.0 - 1.0)
+- **0.3**: Slower, more deliberate pacing
+- **0.5**: Balanced (default)
+- **0.8+**: Faster speech
+
+### Temperature (0.1 - 2.0)
+- **0.5**: Very consistent output
+- **0.8**: Balanced randomness (default)
+- **1.5+**: More creative but less predictable
+
+## 💡 Tips for Best Results
+
+### General Use:
+- Default settings work well for most cases
+- For fast speakers, lower CFG weight to ~0.3
+
+### Expressive Speech:
+- Use lower CFG weight (~0.3) + higher exaggeration (~0.7)
+- Higher exaggeration speeds up speech; lower CFG compensates
+
+### Voice Cloning:
+- Use clear, 3-10 second audio samples
+- Avoid background noise
+- Single speaker recordings work best
