Methods

__call__

abstract Vocoder.__call__(specgrams: Tensor, lengths: Optional[Tensor] = None) → Tuple[Tensor, Optional[Tensor]]

Generate waveform from the given input, such as spectrogram

Parameters:

• specgrams (Tensor) – The input spectrogram. Shape: (batch, frequency bins, time). The expected shape depends on the implementation.

• lengths (Tensor, or None, optional) – The valid length of each sample in the batch. Shape: (batch, ). (Default: None)

Returns:

Tensor:

The generated waveform. Shape: (batch, max length)

Tensor or None:

The valid length of each sample in the batch. Shape: (batch, ).

Return type:

(Tensor, Optional[Tensor])
