from what I learned, the sound WI is spelled ウィ. I've never encountered Japanese who spell it as ウイ, since it will be pronounced as UI, not WI. There are two beats in UI and one beat in WI. So the spelling will effect the pronunciation. I'm a Japanese Language teacher, but definitely not a master in Japanese Language, so I might be wrong - please clarify this, we might learn something new :)
