# Myanmar Text-to-Speech Demo

This Hugging Face Space demonstrates the Myanmar Text-to-Speech (TTS) system developed by [hpbyte](https://github.com/hpbyte/myanmar-tts). It's an end-to-end speech synthesis system specifically designed for the Burmese language.

## ⚠️ IMPORTANT: Model Files Required ⚠️

To use this demo, you **must** upload the following model files to the `trained_model` directory:

1. **checkpoint_latest.pth.tar** - The trained model checkpoint
2. **hparams.yml** - The hyperparameters configuration file

These files can be obtained from the [original repository](https://github.com/hpbyte/myanmar-tts) or by training the model yourself.

## Configuration Instructions

### Setting up the model files:

1. **Create the directory structure**:
   ```bash
   mkdir -p trained_model
   ```

2. **Download and place model files**:
   - Download `checkpoint_latest.pth.tar` and `hparams.yml` from the [release page](https://github.com/hpbyte/myanmar-tts/releases)
   - Place both files in the `trained_model` directory

3. **Verify directory structure**:
   ```
   myanmar-tts-demo/
   ├── app.py
   ├── requirements.txt
   ├── trained_model/
   │   ├── checkpoint_latest.pth.tar
   │   └── hparams.yml
   └── README.md
   ```

4. **Environment setup**:
   - Make sure the PyTorch version matches the one used for training (check `requirements.txt`)
   - The system requires NVIDIA GPU support for optimal performance

### Testing your configuration:

After setting up the model files, run a quick test to verify everything is working correctly:

```python
from synthesis import synthesize_text

# Test with a simple phrase
test_text = "မင်္ဂလာပါ"
audio_output = synthesize_text(test_text)

# If no errors occur, your configuration is correct
```

## About the Project

This is an implementation of Tacotron 2 for Myanmar language text-to-speech synthesis. Unlike Meta's Massively Multilingual Speech (MMS) Burmese TTS, this project is specifically focused on high-quality Burmese speech synthesis using an end-to-end approach.

### Key Features:
- End-to-end Burmese text-to-speech synthesis
- Built on the Tacotron 2 architecture
- Custom text processing for the Myanmar language
- Clean and natural-sounding voice output

## How to Use This Demo

1. **First-time setup**: 
   - Upload the model files as mentioned above to the `trained_model` directory
   - Wait for the Space to rebuild

2. **Using the demo**:
   - Enter Burmese text in the input box
   - Click "Submit" to generate speech
   - Listen to the generated audio output

## Examples

Try these example phrases:
- မင်္ဂလာပါ (Hello)
- မြန်မာစကားပြောစနစ်ကို ကြိုဆိုပါတယ် (Welcome to the Myanmar speech system)
- ဒီစနစ်ဟာ မြန်မာစာကို အသံအဖြစ် ပြောင်းပေးနိုင်ပါတယ် (This system can convert Myanmar text to speech)

## Troubleshooting

If you encounter issues:

1. **Model files not found**: Make sure you've uploaded the required model files to the `trained_model` directory.
2. **App errors**: Try restarting the Space after uploading the model files.
3. **Installation issues**: Check the Space logs for specific error messages.
4. **GPU not detected**: This model requires GPU acceleration. Ensure your Hugging Face Space has GPU access enabled.
5. **Module import errors**: Check that all dependencies are properly installed via the `requirements.txt` file.

## Technical Details

This model uses the Tacotron 2 architecture to generate mel spectrograms from text, which are then converted to waveforms using a vocoder. The model implementation is based on the work by hpbyte.

### System Architecture:
- **Text Frontend**: Processes Myanmar Unicode text
- **Acoustic Model**: Tacotron 2 based sequence-to-sequence model with attention
- **Vocoder**: WaveRNN or Griffin-Lim algorithm for waveform generation
