Tacotron 2
Introduced by Jonathan Shen et al. in Natural TTS Synthesis by Conditioning WaveNet on Mel Spectrogram Predictions
archive 2025-07-28 Description, source and code snippet are the archive's method entry.
Tacotron 2 is a neural network architecture for speech synthesis directly from text. It consists of two components:
- a recurrent sequence-to-sequence feature prediction network with attention which predicts a sequence of mel spectrogram frames from an input character sequence
- a modified version of WaveNet which generates time-domain waveform samples conditioned on the predicted mel spectrogram frames
In contrast to the original Tacotron, Tacotron 2 uses simpler building blocks, using vanilla LSTM and convolutional layers in the encoder and decoder instead of CBHG stacks and GRU recurrent layers. Tacotron 2 does not use a “reduction factor”, i.e., each decoder step corresponds to a single spectrogram frame. Location-sensitive attention is used instead of additive attention.

Usage over time archive 2025-07-28
Components: the archive holds no method-to-method composition, so PwC's Components table cannot be rebuilt; the Papers list carries no Results column for the same reason (the archive does not join its leaderboard rows to method tags).
