Bases: Module

Gaussian Upsample.

Non-attention Tacotron: : - https://arxiv.org/abs/2010.04301

this source code is implemenation of the ExpressiveTacotron from BridgetteSong : - https://github.com/BridgetteSong/ExpressiveTacotron/

Initializes internal Module state, shared by both nn.Module and ScriptModule.

forward(encoder_outputs, durations, vars, input_lengths=None)

Gaussian upsampling.

• Parameters:
  • encoder_outputs – encoder outputs [batch_size, hidden_length, dim]
  • durations – phoneme durations [batch_size, hidden_length]
  • vars – phoneme attended ranges [batch_size, hidden_length]
  • input_lengths – [batch_size]
• Returns: upsampled encoder_output : [batch_size, frame_length, dim]
• Return type: encoder_upsampling_outputs
