either "bigh" or "biy." "i" as in "miss." "gh" a gutteral like Scottish "loch" but with a "g" instead. A "y"ish sound on the end.
...and also if I haven't missed a rule of pronunciation somewhere. I don't speak Irish Gaelic.
I believe the "bui" version has an accent over the i. Not sure about the buidhe version.
