### 🎯 Using Kokoro TTS for High-Quality Fast Synthesis
Kokoro TTS is now integrated as a high-performance, lightweight TTS engine that provides excellent quality with fast generation speeds. Kokoro-82M is an open-weight model with only 82 million parameters, making it significantly faster and more cost-efficient than larger models while delivering comparable quality.
#### Available Kokoro Voices
- **Female American English**: `af_heart`, `af_bella`, `af_sarah`, `af_jessica`, `af_nicole`
- **Male American English**: `am_adam`, `am_michael`
- **Female British English**: `bf_emma`, `bf_isabella`
- **Male British English**: `bm_george`, `bm_daniel`
#### Usage Examples with Kokoro TTS
**Linux/Mac:**
```bash
# Basic Kokoro usage with default voice
./ebook2audiobook.sh --headless --ebook "mybook.epub" --tts_engine KOKORO
# Use a specific Kokoro voice
./ebook2audiobook.sh --headless --ebook "mybook.epub" --tts_engine KOKORO --voice_model "af_heart"
# Male voice example
./ebook2audiobook.sh --headless --ebook "mybook.epub" --tts_engine KOKORO --voice_model "am_adam"
# British English voice
./ebook2audiobook.sh --headless --ebook "mybook.epub" --tts_engine KOKORO --voice_model "bf_emma"
```
**Windows:**
```cmd
# Basic Kokoro usage
ebook2audiobook.cmd --headless --ebook "mybook.epub" --tts_engine KOKORO
# Use a specific Kokoro voice
ebook2audiobook.cmd --headless --ebook "mybook.epub" --tts_engine KOKORO --voice_model "af_bella"
```
#### Kokoro TTS Benefits
- ⚡ **Fast**: Extremely fast synthesis with 82M parameter model
- 💾 **Low Memory**: Requires only ~2GB RAM
- 🔄 **Auto-Download**: Models downloaded automatically when first used
- 🎯 **Quality**: High-quality synthesis comparable to much larger models
- 🌐 **Multi-voice**: Multiple voice options for different characters and styles
- 📖 **Open Source**: Apache-licensed weights for commercial and personal use
- 🚀 **CPU Optimized**: Works efficiently on CPU without requiring GPU
> **Note**: The first time you use Kokoro, the system will automatically download the model files (~200MB). Subsequent uses will be instant.
NOTE: in gradio/gui mode, to cancel a running conversion, just click on the [X] from the ebook upload component.
TIP: if it needs some more pauses, just add '###' or '[pause]' between the words you wish more pause. one [pause] equals to 1.4 seconds
