Oh my. My pronunciation, if even close, tends to wander around dialects. My explanations are even worse.

But I'll take a wild stab at it and we can wait for more input from others.

How do you pronounce these words?:
Cuimhní kwiv NEE
Bhfuil vwil ("wil" might be acceptable in singing and fast speech.)
Dhéanamh YAY a niv In Conamara, I've heard YEE a niv.
Orthu OR ha In Conamara, OR ub.
Achainíocha a khai NEE a kha "kh" is like "rough h" with clearing of the throat.
Mbainfear man far Not sure of the accent or the "f"; it could be pronounced like "h": man har. I suspect "man FAR" around the Decies but elsewhere? Wait for others to correct and comment.
Mbeidh may
Chaitheamh KHA hiv
I'll just jump in to say I don't think I'd ever expect a
b sound at the end of
orthu, but Tim's
OR ha seems fine, as would
OR huh.
I think it's in the conjugated conditional you tend to get the
f pronounced as
h, for the future passive I'd personally expect to hear
f. But, take that for what it is, an L2 speaker's anecdotal evidence.
By the way, Pearl, you may find
this resource more useful for getting pronunciations than the way we try to transcribe them here.
