## Spark-TTS 🔥

### 👉🏻 [Spark-TTS Demos](https://sparkaudio.github.io/spark-tts/) 👈🏻

### 👉🏻 [Github Repo](https://github.com/SparkAudio/Spark-TTS) 👈🏻

### 👉🏻 [Paper](https://arxiv.org/pdf/2503.01710) 👈🏻

### Overview

Spark-TTS is an advanced text-to-speech system that uses the power of large language models (LLM) for highly accurate and natural-sounding voice synthesis. It is designed to be efficient, flexible, and powerful for both research and production use.

## Install
**Clone and Install**

- Clone the repo
``` sh
git clone https://github.com/SparkAudio/Spark-TTS.git
cd Spark-TTS
```

- Install Conda: please see https://docs.conda.io/en/latest/miniconda.html
- Create Conda env:

``` sh
conda create -n sparktts -y python=3.12
conda activate sparktts
pip install -r requirements.txt
```

**Model Download**

Download via python:
```python
from huggingface_hub import snapshot_download

snapshot_download("MrEzzat/Spark_TTS_Arabic", local_dir="pretrained_models/Spark-TTS-0.5B")
```

Download via git clone:
```sh
mkdir -p pretrained_models

# Make sure you have git-lfs installed (https://git-lfs.com)
git lfs install

git clone https://huggingface.co/MrEzzat/Spark_TTS_Arabic
```

**Basic Usage**

You can simply run the demo with the following commands:
``` sh
cd example
bash infer.sh
```

Alternatively, you can directly execute the following command in the command line to perform inference：

``` sh
python -m cli.inference \
    --text "text to synthesis." \
    --device 0 \
    --save_dir "path/to/save/audio" \
    --model_dir pretrained_models/Spark-TTS-0.5B \
    --prompt_text "transcript of the prompt audio" \
    --prompt_speech_path "path/to/prompt_audio"
```

**UI Usage**

You can start the UI interface by running `python webui.py`, which allows you to perform Voice Cloning and Voice Creation. Voice Cloning supports uploading reference audio or directly recording the audio.
