PeriodGrad: Towards Pitch-Controllable Neural Vocoder Based on a Diffusion Probabilistic Model

The article presents research on a neural vocoder based on a denoising diffusion probabilistic model (DDPM), which incorporates explicit periodic signals as auxiliary conditioning signals. The proposed model can generate high-quality waveforms and offers improved pitch control. This development is particularly significant for applications such as speech and singing voice synthesis. The study suggests that this model outperforms conventional DDPM-based neural vocoders in terms of sound quality and pitch control.
