He has a cap and a jersey which are both dark.
Yes, that is one thing I have noted several times during my study on DL. A lot of words are not very specific without the context.
In the specific case I think I was asking if they could hear the 'n' in an audio. If there are many cases where that isn't sufficient, then it's a real problem because we can't hear a silent 'e' either.
