class espnet2.tts.utils.parallel_wavegan_pretrained_vocoder.ParallelWaveGANPretrainedVocoder(model_file: Path | str, config_file: Path | str | None = None)

Bases: Module

Wrapper class to load the vocoder trained with parallel_wavegan repo.

Initialize ParallelWaveGANPretrainedVocoder module.

forward(feats: Tensor, f0: Tensor = None) → Tensor

Generate waveform with pretrained vocoder.

• Parameters:
  • feats (Tensor) – Feature tensor (T_feats, #mels).
  • f0 (Tensor) – f0 information (T_feats)
• Returns: Generated waveform tensor (T_wav).
• Return type: Tensor
