WER for the loanword when validating code-switching ASR model
Hello, I have question for the Error rate for the code-switching ASR model.

There are many loanwords in korean which from english.
For example, "Coffee" is "커피" in korean. These two words have same pronunciation and meaning.

The sentence "커피 마실래?" is "would you want coffee?" in english.

Let's say there is some audio input, and there are two situation in output.

1. "커피 마실래?"
2. "coffee 마실래?"

Actually, both two sentence are correct and natural for korean people. 

Then, how to calculate error rate?
if the label is '커피' then 'coffee' is wrong?
or, '커피' and 'coffee' are both correct?
