give back the question when wrong language is used.
It's not a big deal but it would be nice when this happen we would be told we used the wrong language and being asked again the question for us to use the correct language. Sometimes when we're 'flying' through the exercises this may happened. So it's not wrong but we only use the wrong language. "have a heart DL" :)) this accepts only one languages but this comment is for any learned language. So I picked "English"
i know what you mean, it happens to me too when I listen and type at the same time — I simply do not see that I'm supposed to type what I hear / not translate. I agree it is not a big deal, all the same I liked it better back when Duo told me "wrong language" and let me type again.
Actually, I've gotten this type of message before. I think I typed English when it asked for Russian, and it let me know. But that was way back when, and I don't know if it's still like that.
Edit: Just tested it with Japanese. I didn't get the exact same message, but it's close enough to what you're asking I guess. Perhaps it's different with other languages...
