Sherry - transliterations, non-standardised phonetics, are read differently by different people so arent very useful. You can probably find an online Irish dictionary with sound files to get the sound of individual words and combine that with careful listening to recordings. Best of course is to find a live person to guide you orally.

I just read this and agree. Its in 12:8 time by the way - 12 beats to the bar making it a slip - jig variant I think - I'll need to check. But just having a go at one verse. / marks the end of 6 beats of the bar like in a jig - 6:8 time

line 1
Tiocfaidh m'athair a shí ógó
Chok-ee mahair a / hee go /

2
Anuas fán tráigh a h-óbó
anuas fan trah-ee/ a hobo/

3
Is gheobhaidh sé mise /
is yow - ee sheh mi-sheh

'mo bhradán bhog bháidhte /
mo vradan vog vad-cheh

4
'Gabháil i tsáile i mBaile Leóil
gow-al ee t-s-al-yeh ee / mal-yeh lee-yoh /

Honestly you cant really do it without knowing how to read and pronounce Irish then listening for the dialectical variation
