Official inference code for
SoulX-Singer: Towards High-Quality Zero-Shot Singing Voice Synthesis
🎵 Overview
SoulX-Singer is a high-fidelity, zero-shot singing voice synthesis model that enables users to generate realistic singing voices for unseen singers.
It supports melody-conditioned (F0 contour) and score-conditioned (MIDI notes) control for precise pitch, rhythm, and expression.
✨ Key Features
- 🎤 Zero-Shot Singing – Generate high-fidelity voices for unseen singers, no fine-tuning needed.
- 🎵 Flexible Control Modes – Melody (F0) and Score (MIDI) conditioning.
- 📚 Large-Scale Dataset – 42,000+ hours of aligned vocals, lyrics, notes across Mandarin, English, Cantonese.
- 🧑🎤 Timbre Cloning – Preserve singer identity across languages, styles, and edited lyrics.
- ✏️ Singing Voice Editing – Modify lyrics while keeping natural prosody.
- 🌐 Cross-Lingual Synthesis – High-fidelity synthesis by disentangling timbre from content.

- [2026-02-06] SoulX-Singer inference code and models released.
🚀 Quick Start
1. Clone Repository
git clone https://github.com/Soul-AILab/SoulX-Singer.git
cd SoulX-Singer
2. Set Up Environment
1. Install Conda (if not already installed): https://docs.conda.io/en/latest/miniconda.html
2. Create and activate a Conda environment:
conda create -n soulxsinger -y python=3.10
conda activate soulxsinger
3. Install dependencies:
pip install -r requirements.txt
⚠️ If you are in mainland China, use a PyPI mirror:
pip install -r requirements.txt -i https://mirrors.aliyun.com/pypi/simple/ --trusted-host=mirrors.aliyun.com
3. Download Pretrained Models
Install Hugging Face Hub if needed:
pip install -U huggingface_hub
Download the SVS model and preprocessing models:
pip install -U huggingface_hub
# Download the SoulX-Singer SVS model
hf download Soul-AILab/SoulX-Singer --local-dir pretrained_models/SoulX-Singer
# Download models required for preprocessing
hf download Soul-AILab/SoulX-Singer-Preprocess --local-dir pretrained_models/SoulX-Singer-Preprocess
4. Run the Demo
Run the inference demo:
bash example/infer.sh
This script relies on metadata generated from the preprocessing pipeline, including vocal separation and transcription. Users should follow the steps in preprocess to prepare the necessary metadata before running the demo with their own data.
🚧 Roadmap
- 🖥️ Web-based UI for easy and interactive inference
- 🌐 Online demo deployment on Hugging Face Spaces
- 📊 Release the SoulX-Singer-Eval benchmark
- 📚 Comprehensive tutorials and usage documentation
