substitution, insertion and deletion

[keaixiaovv]

Is there any way to know the times of 'substitution', 'insertion' and 'deletion' ?

Yes, you can!!!.

Instead of printing only HTML of each operation, you can count operations that are occurred while calculating (in word_error_rate.py#L59, #L62, and #L65).

I have achieved the function according to the way you said, thank you very much!
