Yes. And it's not just the data sets, its the fundamental technology. You really need state-of-the-art, ie LSTM/CTC to deal with noisy input data and to get to

Yes. And it's not just the data sets, its the fundamental technology. You really need state-of-the-art, ie LSTM/CTC to deal with noisy input data and to get to 99% accuracy (in addition to excellent data sets of course)
