TIMIT update

[Jan Vanek]

Hi, recently, we have done some improvements on TIMIT:

Average PER 15.58% (15.08% min.) on the core test set. fMLLR, 4x1024 LSTM, http://arxiv.org/abs/1806.07974 It is going to be presented at TSD2018 next week.

Further, we had boosted the result by NN ensembled and by the regularization post-layer in SPECOM 2018 (18.-22. September). Average PER 14.84% (14.69% min.) https://arxiv.org/abs/1806.07186

In addition, we share ready-to-try python scripts here:

To be fair, we had found a nice result of average PER 14.9% by Ravanelli with fMLLR and a M-reluGRU based NN, https://arxiv.org/abs/1710.00641

Thanks, Jan
