waveforms. Addressing the intricate challenge of one-shot many-to-many voice conversion, DiffVC
[432] introduces a novel solver based on stochastic differential equations. Expanding the scope of
sound generation to include singing voice synthesis, DiffSinger [334] introduces a shallow diffusion
mechanism. Additionally, Diffsound [611] proposes a sound generation framework that incorporates
text conditioning and employs a discrete diffusion model, effectively resolving concerns related to
unidirectional bias and accumulated errors.
