espnet2.gan_tts.jets.alignments.average_by_duration(ds, xs, text_lengths, feats_lengths)

Average frame-level features into token-level according to durations

• Parameters:
  • ds (Tensor) – Batched token duration (B, T_text).
  • xs (Tensor) – Batched feature sequences to be averaged (B, T_feats).
  • text_lengths (Tensor) – Text length tensor (B,).
  • feats_lengths (Tensor) – Feature length tensor (B,).
• Returns: Batched feature averaged according to the token duration (B, T_text).
• Return type: Tensor
