the most difficult to understand when they speak english are people from japan, Korea dan taiwan. When my friend from japan try to speak english i can't understand what he want to say. then i asked him to speak japanese. but when i met another one, she can speak fluently. so i think its depend on their skill.

Well, I don't listen to English, but when I listen to Japanese, I listen mostly to the pronunciation.
I think it is easier for me to listen to young female voices. This is probably because I am a young female.
I don't often hear Japanese being spoken by non-native speakers. I try to avoid listening to non-native speakers.
