Ro-Matcha-TTS

Matcha-TTS Romanian Models

Pre-trained Romanian text-to-speech models based on Matcha-TTS trained on the SWARA 1.0 dataset.

Quick Start

Clone Repository

Since this repository contains custom inference code and model loading utilities, you need to clone it:

# Clone from HuggingFace Hub
git clone https://huggingface.co/adrianstanea/Ro-Matcha-TTS
cd Ro-Matcha-TTS

# Install Git LFS (if not already installed) to download large model files
git lfs install
git lfs pull

Installation

# Install system dependencies (required for phonemization)
sudo apt-get install espeak-ng

# Install the main Matcha-TTS repository
pip install git+https://github.com/adrianstanea/Matcha-TTS.git

# Install required dependencies
pip install -r requirements.txt

Usage

import sys
sys.path.append("src")
from model_loader import ModelLoader

# Load from local cloned repository
loader = ModelLoader.from_pretrained("./")

# List available models
print(loader.list_models())
# {'swara': {...}, 'bas_10': {...}, 'bas_950': {...}, ...}

# Load production-ready BAS speaker
model_info = loader.load_models(model="bas_950")
print(f"Model: {model_info['model_name']}")
print(f"Path: {model_info['model_path']}")

# Load few-shot SGS speaker
model_info = loader.load_models(model="sgs_10")
print(f"Training data: {model_info['model_info']['training_data']}")

# Use with original Matcha-TTS inference code
# See examples/inference_example.py for complete usage

Run Example

cd examples
python inference_example.py

Available Models

Baseline Model

Fine-tuned Speaker Models

Vocoder: Universal HiFi-GAN vocoder

Research Methodology

• Training Strategy: Baseline → Speaker Fine-tuning (100 epochs)
• Data Efficiency Study: 10 vs 950 samples comparison
• Low-Resource Learning: Demonstrates few-shot TTS adaptation

Model Details

• Architecture: Matcha-TTS (Conditional Flow Matching)
• Dataset: SWARA 1.0 Romanian Speech Corpus
• Sample Rate: 22,050 Hz
• Language: Romanian (ro)
• Text Processing: eSpeak Romanian phonemizer
• Model Size: ~100M parameters per model

Usage with Original Repository

This repository provides model weights and HuggingFace integration. For training, evaluation, and advanced features, use the main repository.

# After loading models with ModelLoader
from matcha.models.matcha_tts import MatchaTTS
import torch

# Load using paths from ModelLoader
model = MatchaTTS.load_from_checkpoint(model_info['model_path'])
# ... continue with original inference code

Requirements

• Python 3.10
• Main Matcha-TTS repository for inference
• HuggingFace Hub for model downloading

License

Same as the original Matcha-TTS repository.
