UniSinger addresses the historical isolation between song generation and singing voice conversion by introducing a unified framework that enables zero-shot speaker cloning alongside vocal-accompaniment synergy. By leveraging a multimodal diffusion transformer with curriculum learning, the model resolves multi-task optimization conflicts to achieve state-of-the-art performance in both domains. This advancement offers a practical solution for intelligent music production, effectively bridging the gap between independent generative tasks through shared speaker embeddings.
Towards Unified Song Generation and Singing Voice Conversion with Accompaniment Co-Generation
arXiv:2606.07015v1 Announce Type: cross Abstract: While song generation and singing voice conversion (SVC) have evolved significantly, they have long been developed isolated: the former lacks zero-shot speaker cloning, while the latter overlooks vocal-accompaniment synergy. To bridge this gap, we propose UniSinger, the first end-to-end framework unifying speaker cloning song generation and accompaniment co-generation SVC. Building on the multimodal diffusion transformer, we construct a unified speaker embedding space transferring speaker representation from SVC to song generation, endowing fine-grained cross-task timbre control. To mitigate multi-task optimization conflicts, we design a curriculum learning strategy using task-specific modality masking to guide the model to gradually master the generative mechanisms among semantic content, vocal timbre, and accompaniment. Experiments show state-of-the-art performance on both tasks and realizes complementary benefits, offering new possibilities for intelligent music production.
