## **Thonburian TTS**

**Thonburian TTS** is a **Thai Text-to-Speech (TTS)** engine built on top of the [F5-TTS](https://github.com/SWivid/F5-TTS).  
It generates **natural and expressive Thai speech** by leveraging **Flow-Matching diffusion techniques** and can **mimic reference voices** from short audio samples. The system supports:

- **Thai language generation** (`language="th"`)
- **Reference-based voice cloning** using short audio clips
- High-quality synthesis with controllable speed and silence trimming

## **Quick Usage**

### **Installation**

Install dependencies:

```bash
pip install torch cached-path librosa transformers f5-tts
sudo apt install ffmpeg
```

### **Clone GitHub**

```
git clone https://github.com/biodatlab/thonburian-tts.git
cd thonburian-tts
```

#### **Loading Thai Script based Models** 
```py
from flowtts.inference import FlowTTSPipeline, ModelConfig, AudioConfig
import torch

# Configure F5-TTS model
model_config = ModelConfig(
    language="th",
    model_type="F5",
    checkpoint="hf://biodatlab/ThonburianTTS/megaF5/mega_f5_last.safetensors",
    vocab_file="hf://biodatlab/ThonburianTTS/megaF5/mega_vocab.txt",
    vocoder="vocos",
    device="cuda" if torch.cuda.is_available() else "cpu"
)

# Basic audio settings
audio_config = AudioConfig(
    silence_threshold=-45,
    cfg_strength=2.5,
    speed=1.0
)

pipeline = FlowTTSPipeline(model_config, audio_config)
```


#### **Loading IPA based Models** 
```py
from flowtts.inference import FlowTTSPipeline, ModelConfig, AudioConfig
import torch

# Configure F5-TTS model
model_config = ModelConfig(
    model_type="F5",
    checkpoint="hf://biodatlab/ThonburianTTS/megaIPA/model_last_prune.safetensors",
    vocab_file="hf://biodatlab/ThonburianTTS/megaIPA/mega_vocab_ipa.txt",
    vocoder="vocos",
    device="cuda" if torch.cuda.is_available() else "cpu"
)

# Basic audio settings
audio_config = AudioConfig(
    silence_threshold=-45,
    cfg_strength=2.5,
    speed=1.0
)

pipeline = FlowTTSPipeline(model_config, audio_config)
```
