Summary:
To match the correct batch size of 64 mentioned in the source code and paper.
Source: https://arxiv.org/pdf/1712.05884.pdf
Code: https://github.com/NVIDIA/tacotron2/blob/bb6761349354ee914909a42208e4820929612069/hparams.py#L84
Also, due to the larger batch size, I needed to add more .wav files (186), since the old dataloader only had 2 .wav files.
