Source-Filter HiFi-GAN: Fast and Pitch Controllable High-Fidelity Neural Vocoder. (arXiv:2210.15533v2 [cs.SD] UPDATED)

Our previous work, the unified source-filter GAN (uSFGAN) vocoder, introduced
a novel architecture based on the source-filter theory into the parallel
waveform generative adversarial network to achieve high voice quality and pitch
controllability. However, the high temporal resolution inputs result in high
computation costs. Although the HiFi-GAN vocoder achieves fast high-fidelity
voice generation thanks to the efficient upsampling-based generator
architecture, the pitch controllability is severely limited. To realize a fast
and pitch-controllable high-fidelity neural vocoder, we introduce the
source-filter theory …
