It's often said that the purpose of Irish spelling is to disguise the pronunciation!
Your best bet would be to post the titles you're interested in, and I'm sure one of the many Irish speakers on Mudcat will give you a phonetic version. there are, of course, dialect differences to contend with too. (i originally learnt Munster Irish and am now concentrating on Donegal Irish)
