Can't recognize consecutive same charactors

[RaisingSun]

Hi, I read your excellent paper and use your code to do some experiment. But I found it can not recognize the consecutive charactor when they are same. For example, "good" will be recognized as "god".
Could you please help me about this problem?
Thanks

The model should learn to emit the blank character between repeats so the CTC decoding doesn't collapse them.

Thanks for your response. You mean I have to add blank character between repeats in label?

@RaisingSun I have the same issue. Can you help?

@RaisingSun No, you do not add the blank in the label. If your training schedule is sufficient, it will learn to emit the blank so as to force the repeat character after collapsing. Training the model is very sensitive to local minima. See e.g. #42 (comment)
