WebJan 14, 2024 · A Pytorch Implementation of Neural Speech Synthesis with Transformer Network This model can be trained about 3 to 4 times faster than the well known seq2seq model like tacotron, and the quality of synthesized speech is almost the same. It was confirmed through experiment that it took about 0.5 second per step. WebRelative Position Encodings are a type of position embeddings for Transformer-based models that attempts to exploit pairwise, relative positional information. Relative positional information is supplied to the model on two levels: values and keys. This becomes apparent in the two modified self-attention equations shown below.
