Fine-tuned Arabic XTTS Model

This is a fine-tuned XTTS model for Arabic Text-to-Speech. It has been trained to generate highly natural Arabic speech, taking advantage of a reference audio file for zero-shot voice cloning.

How to Use

You can easily use this model in Python. The following code downloads the model.pth, config.json, and vocab.json directly from this repository, initializes the model, and safely processes long Arabic text by splitting it into smaller sentence chunks.

Prerequisites

This model was trained and tested using Python 3.10 (specifically 3.10.18). To run the inference code, you will need to install system-level audio libraries and specific Python dependencies.

1. Install System Audio Dependencies (Linux/Ubuntu): You need FFmpeg to handle audio processing natively. Run this in your terminal:

bash

sudo apt update
sudo apt install ffmpeg libavcodec-dev libavutil-dev libavformat-dev

2. Install Python Dependencies: Install the core TTS library directly from the Coqui GitHub repository, along with the specific version of Transformers required for compatibility:

bash

pip install git+[https://github.com/coqui-ai/TTS](https://github.com/coqui-ai/TTS)
pip install transformers==4.33.0
pip install torchcodec torch torchaudio huggingface_hub

Inference Code

# Users can replace this with their own local file path if they want to clone a different voice

    )
    
    wav_chunks.append(torch.tensor(out["wav"]))
