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.
For more details, please refer to the paper: SoulX-Singer: Towards High-Quality Zero-Shot Singing Voice Synthesis.
Features
- Zero-shot synthesis: Generate singing voices for unseen singers without fine-tuning
- Melody-conditioned control: Use F0 contour for pitch guidance
- Score-conditioned control: Use MIDI notes for precise musical notation
- High-fidelity output: Realistic vocal synthesis with natural expression
- Safetensors format: Optimized model weights in bf16 + fp32 precision
