Very interesting. Thanks for the references. Have you released the code or pre-trained models yet or do you plan to do so at some point?

The code is all released already. You find it here: https://github.com/rwth-i6/returnn-experiments/tree/master/2...

This is TensorFlow-based. But I also have another PyTorch-based implementation already, also public (inside our other repo, i6_experiments). It's not so easy currently to set this up, but I'm working on a simpler pipeline in PyTorch.

We don't have the models online yet, but we can upload them later. But I'm not sure how useful they are outside of research, as they are specifically for those research tasks (Librispeech, Tedlium), and probably don't perform too well on other data.
