Hi Dave! I'll give this one a shot; although, it's very hard to translate the spoken word to mere letters. Just a note, the 'ch' in 'bhuachail' is a very soft guttural sound, much like the 'ch' in the word 'Chanukah.' So, here goes:

bhuachail = woo-ah-chuhl

The emphasis should be on the first syllable. I hope this helps.

All the best, Áine
